Background technique

The 16-bit video network protocol and the 64-bit video network protocol are two completely different protocols in the video network. The download process for the application upgrade package is also completely different. The original upgrade program based on the 16-bit protocol only supports the upgrade from the 16-bit video network protocol to the 16-bit video network protocol. The upgrade package cannot be downloaded from a server based on the 64-bit video networking protocol (i.e., a 16-bit server). The upgrade package cannot be downloaded from a server based on the 64-bit video networking protocol (i.e., a 64-bit server).

At present, because 16-bit servers can no longer meet the business needs of video networking, 16-bit servers are gradually being replaced by 64-bit servers. Before replacing a 16-bit server with a 64-bit server, usually the terminal under the 16-bit server first downloads the upgrade program that supports the 64-bit video networking protocol from the 16-bit server, then replaces the 16-bit server with a 64-bit server, and installs the upgrade program that supports 64-bit video networking protocol. Terminals that use the upgrade program of the Internet protocol can access the 64-bit server.

However, if some terminals under the 16-bit server are not powered on, the unpowered terminals will not be able to download the upgrade program that supports the 64-bit video networking protocol from the 16-bit server.

Detailed ways

In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

It should be understood that the specific embodiments described here are only used to explain the present invention. They are only some embodiments of the present invention, not all embodiments, and are not used to limit the present invention.

Referring to Figure 1, Figure 1 is a step flow chart of a program upgrade method provided in an embodiment of the present invention. The method is applied to a video network proxy component that supports the first video network protocol. The video network agent component is installed on a video network terminal or View the network server. The method of this embodiment includes the following steps:

Step 101: Read the preconfigured configuration information. The configuration information includes the terminal information of the video network terminal that supports the first video network protocol to be upgraded, the upgrade channel information of each video network terminal, and the upgrade package corresponding to each upgrade channel information. information.

Among them, the configuration information can be configured in a configuration file, or the configuration information can be configured in a data table of a database. The terminal information includes the address information of the video network terminal. The address information is, for example, a Media Access Control (MAC) address. The configuration information may include the MAC address of the video network terminal that supports the first video network protocol to be upgraded, and each video network terminal. The upgrade channel information of the networked terminal and the upgrade package information corresponding to each upgrade channel information. Wherein, the upgrade channel information of the video network terminal is, for example, a channel identifier, and the upgrade package information corresponding to the channel information includes the storage path and version identifier of the upgrade package corresponding to the channel information. The video network agent component can read the configuration information to obtain the terminal information of the video network terminal, the upgrade channel information of each video network terminal, and the upgrade package information corresponding to each upgrade channel information. It should be noted that the upgrade channel information of the same type of video network terminals can be the same, that is, the corresponding upgrade package information of the same type of video network terminals is the same. Types of video network terminals include, for example, terminal types such as type A and type B.

Among them, the first video networking protocol may be a 16-bit video networking protocol. A video terminal that supports the first video protocol to be upgraded refers to a terminal that has not undergone the upgrade procedure to support the second video protocol upgrade procedure.

Step 102: Determine the target video network terminal to be upgraded, and send a network access instruction to the target video network terminal according to the terminal information of the target video network terminal.

It should be noted that the terminal status corresponding to each terminal information is stored in the visual network agent component. For example, if there are 100 pieces of address information in the configuration information, the Internet of Things proxy component can traverse each address information in turn. If the terminal status corresponding to the currently traversed address information is idle, the terminal corresponding to the address information can be used as the target. View network terminal. If the terminal status corresponding to the currently traversed address information is not in the idle state, then the next address information is traversed, and the terminal status corresponding to the address information is determined. If the terminal status is idle, the view corresponding to the address information is The networked terminal is regarded as the target networked terminal.

It should be noted that after determining the target video network terminal, the video network agent component can send a network access instruction to the target video network terminal according to the terminal information of the target video network terminal. The network access instruction can include two instructions. The first instruction is the port. Query the command. After receiving the first command, the target video network terminal can send a port response command to the video network agent component. The port response command includes the upgrade package information of the upgrade program installed on the target video network terminal. The upgrade package information includes The channel information corresponding to the upgrade program (the channel information is, for example, a channel identifier), the version identifier of the upgrade program (the version identifier is, for example, version update time information), and the version update time information refers to the date and time point of the version update of the upgrade program, For example, the version update time information is the time on a certain day of a certain month of a certain year. After receiving the port response command, the VideoNet proxy component sends a second command to the target VideoNet terminal. This command is used to instruct the target VideoNet terminal to access the VideoNet terminal or the VideoNet server deployed by the VideoNet proxy component. The target VideoNetwork After receiving the second instruction, the terminal can access the video network terminal or video network server deployed by the network video network agent component.

Step 103: After the target video network terminal is connected to the network, determine the target upgrade package information corresponding to the target upgrade channel information based on the target upgrade channel information of the target video network terminal, and send the upgrade package corresponding to the target upgrade package information to the target video network terminal. The upgrade package includes: upgrading the upgrade program of the target video network terminal that supports the first video network protocol to a program upgrade package that supports the second video network protocol.

Among them, after the target video network terminal is determined, the port response command sent to the video network agent component by the target video network terminal during the network access process includes the channel information and version identification corresponding to the upgrade program installed on the target video network terminal (the version identification can be the version update time information corresponding to the upgrade program installed on the target video network terminal). Therefore, the video network agent component can determine the channel corresponding to the upgrade channel information in the configuration information based on the channel information included in the port response command. Upgrade channel information with the same information, and use the upgrade channel information that is the same as the channel information as the target upgrade channel information. The video network agent component can therefore determine the target upgrade package information corresponding to the target upgrade channel information (for example, the upgrade channel information 1 corresponds to the upgrade package information) based on the target upgrade channel information of the target video network terminal and the upgrade package information corresponding to each upgrade channel information. 1. Upgrade channel information 2 corresponds to upgrade package information 2. When the target upgrade channel information is upgrade channel information 1, upgrade package information 1 is the target upgrade package information). After the target upgrade package information is determined, the upgrade package corresponding to the target upgrade package information can be obtained based on the target upgrade package information. For example, the upgrade package is obtained according to the storage path in the target upgrade package information, and the upgrade package is sent to the target video network terminal. For example, the channel information included in the port response command is channel 8, then channel 8 in each upgrade channel information in the configuration information is the target upgrade channel information, and the upgrade package information corresponding to channel 8 is the target upgrade package information, and based on Obtain the upgrade package from the storage path in the target upgrade package information, and then send the upgrade package to the target video network terminal.

It should be noted that the second video networking protocol includes a 64-bit video networking protocol. For example, the second video networking protocol is a 64-bit video networking protocol, or the second video networking protocol is a 64-bit video networking protocol and a 16-bit video networking protocol. That is, the program upgrade package supports the 64-bit video networking protocol, or the program upgrade package supports the 16-bit video networking protocol and the 64-bit video networking protocol. The upgrade package includes upgrading the upgrade program of the target video network terminal that supports the first video network protocol to a program upgrade package that supports the second video network protocol, that is, the upgrade package is an upgrade package that can support the 64-bit video network protocol. When the second video network protocol is a 64-bit video network protocol and a 16-bit video network protocol, after upgrading the upgrade program of the target video network terminal that supports the first video network protocol to a program upgrade package that supports the second video network protocol , the upgrade program on the target video network terminal is upgraded to an upgrade program that supports the second video network protocol. The target video network terminal can access the 64-bit video network server through the upgrade program that supports the second video network protocol, or it can also access the network through the upgrade program that supports the second video network protocol. The networking protocol upgrade program is integrated into the 16-bit video networking server.

The program upgrade method provided in this embodiment reads pre-configured configuration information. The configuration information includes terminal information of the video network terminal that supports the first video network protocol to be upgraded, upgrade channel information of each video network terminal, and each video network terminal. The upgrade package information corresponding to the upgrade channel information determines the target video network terminal to be upgraded, and sends a network access instruction to the target video network terminal according to the terminal information of the target video network terminal. After the target video network terminal joins the network, the target video network terminal is sent to the network according to the terminal information of the target video network terminal. The target upgrade channel information determines the target upgrade package information corresponding to the target upgrade channel information, and sends an upgrade package corresponding to the target upgrade package information to the target video network terminal. The upgrade package includes: converting the target video network terminal that supports the first video network protocol The upgrade program is upgraded to a program upgrade package that supports the Second Vision Networking Protocol. Realize the upgrade program of the target video network terminal that supports the first video network protocol to an upgrade program that supports the second video network protocol. Among them, the program upgrade package supports the 64-bit video network protocol, that is, the second video network protocol includes 64-bit video network protocols. The video network protocol enables the target video network terminal to access the 64-bit video network server through an upgrade program that supports the second video network protocol.

Referring to Figure 2, Figure 2 is a flow chart of another program upgrade method provided by an embodiment of the present invention. The method includes the following steps:

Step 201: Read pre-configured configuration information.

The configuration information may include the number of terminals of all video network terminals to be upgraded that support the first video network protocol. Therefore, the number of terminals of all video network terminals to be upgraded that support the first video network protocol can be obtained by reading the configuration information.

Step 202: Determine whether the number of terminals is equal to zero.

If the number of terminals is not equal to zero, step 203 is executed; if the number of terminals is equal to zero, the process ends directly.

Step 203: Determine whether the number of currently traversed terminals is less than the number of terminals.

If the number of terminals currently traversed is less than the number of terminals, step 204 is executed; if the number of terminals currently traversed is not less than the number of terminals, step 202 is executed for the next round of traversal. That is, if the number of terminals is 100, after the first round of traversing 100 terminals is completed, the second round of traversal can be performed to continue traversing these 100 terminals. The initial value of the current number of traversed terminals before the first round of traversal is equal to 0.

Step 204: Determine the target video network terminal to be upgraded, and send a network access instruction to the target video network terminal according to the terminal information of the target video network terminal.

Among them, step 204 can be implemented through the following steps:

According to the stored terminal information of the video network terminal and the terminal status corresponding to the stored terminal information of the video network terminal, the video network terminal in the idle state is determined, and the video network terminal in the idle state is used as the target video network terminal, and Send a network access instruction to the target video network terminal according to the terminal information of the target video network terminal.

It should be noted that the terminal status corresponding to each terminal information can be traversed in sequence. If the terminal status of a currently traversed video network terminal is not an idle state, the number of currently traversed terminals is accumulated by 1. If the terminal status of a currently traversed video network terminal is idle, the currently traversed video network terminal is used as the target video network terminal. Among them, the terminal status of a certain video network terminal is not idle means that the video network terminal is currently in the upgrade state of the upgrade program, that is, the video network terminal is currently downloading the upgrade package of the upgrade program; the terminal status of the video network terminal is The idle state means that the video network terminal is not currently downloading the upgrade package of the upgrade program.

Before determining the target video network terminal to be upgraded, the following steps can also be included:

Determine whether the video network proxy component is in an idle state. If the video network proxy component is in an idle state, determine the target video network terminal to be upgraded. If the video network proxy component is not in an idle state, it is prohibited to traverse the currently traversed terminal. The next terminal adjacent to the last terminal in . Through this step, the video network agent component can only send an upgrade package to one video network terminal at a time, thereby saving the bandwidth occupied by the video network agent component in sending the upgrade package to the video network terminal. Among them, the configuration information can be configured with a bandwidth size. For example, if the bandwidth is configured to be 2M, then the video network proxy component occupies 2M of network bandwidth to send an upgrade package to the target video network terminal. It should be noted that before determining the target video network terminal to be upgraded, it is not necessary to determine whether the video network agent component is in an idle state. In this case, the video network agent component can download and upgrade to multiple video network terminals at the same time. Package, if the configured bandwidth is 2M and the video network agent component downloads the upgrade package to three video network terminals at the same time, the video network agent component needs to occupy 6M of network bandwidth to send the upgrade package to these three video network terminals.

For example, if there are 100 video network terminals in total, and the currently traversed terminals are video network terminal 1 to video network terminal 9, if it is determined that the video network agent component is not idle before determining the target video network terminal to be upgraded, such In this case, the video network proxy component does not need to traverse the video network terminal 10 (the terminal 10 is the next terminal, that is, there is no need to determine whether the video network terminal 10 is in an idle state); if it is determined that the video network agent component is in an idle state, it traverses the video network terminal 10. If the video network terminal 10 is in an idle state, the video network terminal 10 serves as the target video network terminal.

It should be noted that, for example, if the number of terminals currently traversed is represented by i, i=9; then the video network terminal 10 is traversed, and the video network terminal 10 is idle, and the first instruction in the network access command is sent to the video network terminal 10 , but the port response command of the video network terminal 10 was not received within the preset time period, that is, the channel information and version identification of the upgrade program installed on the video network terminal 11 was not received within the preset time period. In order to avoid the video network terminal 11 For the waiting time of the agent component, the video network agent component can accumulate the number of terminals that have been traversed currently by 1, that is, i = 10 after accumulating 1, and then traverse the video network terminal 11. If the status of the video network terminal 11 is idle, then at this time The network terminal 11 is regarded as the target network terminal.

Step 205: After the target video network terminal is connected to the network, determine the target upgrade package information based on the upgrade package information corresponding to each upgrade channel information. The target upgrade package information includes the storage path and first version identification corresponding to the upgrade package.

The first version identifier may be version update time information corresponding to the upgrade package. Based on the introduction of the above embodiments, the video network agent component can obtain the target upgrade package information through the channel information corresponding to the upgrade program installed on the target video network terminal included in the port response command sent by the target video network terminal. Since the target upgrade package information includes the storage path of the upgrade package and the version identifier corresponding to the upgrade package. The version identifier corresponding to the upgrade package included in the target upgrade package information is the first version identifier, that is, the first version identifier is the version update time information corresponding to the upgrade package. . It should be noted that the first version identifier can also be the version number corresponding to the upgrade package.

Step 206: Determine whether the upgrade program needs to be upgraded based on the first version identifier and the second version identifier of the upgrade program.

The second version identification of the upgrade program may be the version update time information of the upgrade program currently installed on the target video network terminal. Based on the introduction of the above embodiments, the video network agent component can respond to the version identifier included in the instruction through the port sent by the target video network terminal (the version identifier can be the version update time information corresponding to the upgrade program installed on the target video network terminal), Determine the second version identification of the upgrade program, that is, the second version identification may be version update time information corresponding to the upgrade program installed on the target video network terminal. The second version identifier may also be a version number corresponding to the upgrade program installed on the target video network terminal.

Determine whether the upgrade program needs to be upgraded based on the first version identifier and the second version identifier of the upgrade program. For example, after obtaining the version update time information of the upgrade program installed on the target video network terminal and the version update time information corresponding to the upgrade package, the version update time information of the upgrade program installed on the target video network terminal and the version corresponding to the upgrade package can be obtained. Update time information to determine whether the upgrade program needs to be upgraded. For example, if the update time information of the version of the upgrade program installed on the target video network terminal is earlier than the version update time information corresponding to the upgrade package, it is determined that the upgrade program needs to be upgraded.

Alternatively, after obtaining the version number of the upgrade program installed on the target video network terminal and the version number corresponding to the upgrade package, you can determine whether an upgrade is required based on the version number of the upgrade program installed on the target video network terminal and the version number corresponding to the upgrade package. Upgrade procedure. For example, if the version number of the upgrade program installed on the target video network terminal is lower than the version number corresponding to the upgrade package, it is determined that the upgrade program needs to be upgraded.

It should be noted that after the video network agent component receives the port response command sent by the target video network terminal, the video network agent component can send a second instruction to the target video network terminal. If the target video network terminal successfully accesses the network, the target video network terminal will Send the response command of the network access command to the video network proxy component. Among them, the second instruction sent by the Internet of Things agent component to the target Internet of Things terminal may include the channel information stored on the Internet of Things agent component and the port response instruction (the channel information in the port response instruction is the same as the target upgrade channel information) The corresponding upgrade package information (the upgrade package information may include the storage path and version update time information of the upgrade package corresponding to the target upgrade channel information), so that after the target video network terminal receives the version update time information sent by the video network agent component, it can Compare the version update time information sent by the video network agent component with the version update time information of the upgrade program installed on the target video network terminal to determine whether it is necessary to start the locally installed upgrade program. For example, if the target video network terminal receives the version update time information of the upgrade package sent by the video network agent component and the version update time information of the upgrade program installed on the target video network terminal, the target terminal can start the locally installed upgrade program. .

Step 207: If the upgrade program needs to be upgraded, obtain the upgrade package according to the storage path, and send the upgrade package to the target video network terminal.

During the process of sending the upgrade package to the target video network terminal, the status of the video network proxy component can be set to a non-idle state, and the status of the target video network terminal can be set to a non-idle state.

After the data packet of the upgrade package is sent, the status of the target video network terminal can be set to the idle state, the status of the video network proxy component can be set to the idle state, and the number of currently traversed terminals can be accumulated by 1.

Through the method provided in this embodiment, it is possible to upgrade the video Internet terminals supporting the first video Internet protocol that need to be upgraded in the configuration information, that is, the upgrade procedure of the video Internet terminals that support the first video Internet protocol that need to be upgraded in the configuration information. Upgrade program to support Second Vision Networking Protocol. Moreover, by judging whether the upgrade program needs to be upgraded based on the first version identification and the second version identification of the upgrade program, if the upgrade program needs to be upgraded, the upgrade program is upgraded to avoid the confusion between the first version identification and the second version identification of the upgrade program. When the second version ID is the same, upgrading the upgrade program causes a waste of bandwidth resources.

In order for those skilled in the art to better understand the embodiments of the present invention, the video network is introduced below:

Some of the technologies used in the Internet of Vision are as follows:

Network Technology

The network technology innovation of VideoNet improves traditional Ethernet to face the potentially huge video traffic on the network. Different from simple network packet switching (Packet Switching) or network circuit switching (CircuitSwitching), video networking technology uses Packet Switching to meet streaming needs. Video networking technology has the flexibility, simplicity and low price of packet switching, while also possessing the quality and security guarantee of circuit switching, realizing network-wide switched virtual circuits and seamless connection of data formats.

Switching Technology

The Internet of Vision adopts the two advantages of Ethernet's asynchronous and packet switching, and eliminates the defects of Ethernet on the premise of full compatibility. It has end-to-end seamless connection across the entire network, passes directly to user terminals, and directly carries IP data packets. User data does not require any format conversion across the entire network. Video Internet is a more advanced form of Ethernet. It is a real-time switching platform that can realize large-scale real-time transmission of high-definition video across the entire network that is currently unachievable on the Internet, pushing many online video applications to high-definition and unification.

Server Technology (ServerTechnology)

The server technology on the Internet of Things and Unified Video Platform is different from servers in the traditional sense. Its streaming media transmission is based on connection-oriented. Its data processing capabilities have nothing to do with traffic and communication time. A single network layer can contain information. order and data transmission. For voice and video services, the complexity of streaming media processing on the video network and unified video platform is much simpler than data processing, and the efficiency is greatly improved by more than a hundred times compared with traditional servers.

Storage Technology

In order to adapt to ultra-large capacity and ultra-large flow of media content, the ultra-high-speed storage technology of the unified video platform adopts the most advanced real-time operating system to map the program information in the server instructions to specific hard disk space. The media content no longer passes through the server. It is delivered directly to the user terminal instantly, and the user's waiting time is generally less than 0.2 seconds. The optimized sector distribution greatly reduces the mechanical movement of the hard disk head seeking. The resource consumption only accounts for 20% of the same level of IP Internet, but it generates 3 times more concurrent traffic than traditional hard disk arrays, and the overall efficiency is increased by more than 10 times.

Network Security Technology

The structural design of the Internet of Things has completely eradicated the network security issues that plague the Internet through separate licensing for each service and complete isolation of equipment and user data. Generally, anti-virus programs and firewalls are not required, and attacks by hackers and viruses are eliminated. , providing users with a structured, worry-free secure network.

Service Innovation Technology

The unified video platform integrates services and transmission. Whether it is a single user, a private network user or a network in total, it is just an automatic connection. User terminals, set-top boxes or PCs are directly connected to the unified video platform to obtain a variety of multimedia video services in various forms. The unified video platform uses a "recipe-style" table configuration model to replace traditional complex application programming. It can implement complex applications with very little code and achieve "unlimited" new business innovation.

The networking of the video network is as follows:

The visual network is a centralized control network structure. The network can be a tree network, a star network, a ring network, etc., but on this basis, a centralized control node is needed in the network to control the entire network.

As shown in Figure 4, the video network is divided into two parts: the access network and the metropolitan area network.

The equipment in the access network can be mainly divided into three categories: node servers, access switches, and terminals (including various set-top boxes, coding boards, memories, etc.). The node server is connected to the access switch, and the access switch can be connected to multiple terminals and can be connected to Ethernet.

Among them, the node server is a node with a centralized control function in the access network and can control access switches and terminals. The node server can be directly connected to the access switch or directly connected to the terminal.

Similarly, the equipment in the metropolitan area network can also be divided into three categories: metropolitan area servers, node switches, and node servers. Metro servers are connected to node switches, and node switches can be connected to multiple node servers.

Among them, the node server is the node server of the access network part, that is, the node server belongs to both the access network part and the metropolitan area network part.

The metropolitan area server is a node with a centralized control function in the metropolitan area network and can control node switches and node servers. Metro servers can be directly connected to node switches or node servers.

It can be seen that the entire Vision Network is a hierarchical centralized control network structure, and the network controlled by the node server and the metropolitan area server can be a tree, star, ring and other structures.

To put it graphically, the access network part can form a unified video platform (the part in the dotted circle), and multiple unified video platforms can form a video network; each unified video platform can be interconnected through metropolitan and wide-area video networks.

Visual network device classification

1.1 The equipment in the visual network according to the embodiment of the present invention can be mainly divided into three categories: servers, switches (including Ethernet gateways), and terminals (including various set-top boxes, coding boards, memories, etc.). The video network as a whole can be divided into metropolitan area network (or national network, global network, etc.) and access network.

1.2 The equipment in the access network can be mainly divided into three categories: node servers, access switches (including Ethernet gateways), and terminals (including various set-top boxes, encoding boards, memories, etc.).

The specific hardware structure of each access network equipment is:

Node server:

As shown in Figure 5, it mainly includes a network interface module 501, a switching engine module 502, a CPU module 503, and a disk array module 504;

Among them, the incoming packets from the network interface module 501, the CPU module 503, and the disk array module 504 all enter the switching engine module 502; the switching engine module 502 performs an address table 505 operation on the incoming packets, thereby obtaining the packet guidance information; and based on The packet guidance information stores the packet in the queue of the corresponding packet buffer 506; if the queue of the packet buffer 506 is close to full, it is discarded; the switching engine module 502 polls all packet buffer queues and forwards it if the following conditions are met: 1) The send buffer of the port is not full; 2) The packet counter of the queue is greater than zero. The disk array module 504 mainly implements the control of the hard disk, including initialization, reading and writing of the hard disk and other operations; the CPU module 503 is mainly responsible for protocol processing with the access switch and terminal (not shown in the figure), and the address table 505 (including the configuration of the downstream protocol packet address table, the upstream protocol packet address table, and the data packet address table), and the configuration of the disk array module 504.

Access switch:

As shown in Figure 6, it mainly includes network interface modules (downlink network interface module 601, uplink network interface module 602), switching engine module 603 and CPU module 604;

Among them, the incoming packets (uplink data) from the downlink network interface module 601 enter the packet detection module 605; the packet detection module 605 detects whether the destination address (DA), source address (SA), data packet type and packet length of the packet meet the requirements. If If it matches, the corresponding stream identifier (stream-id) is allocated and enters the switching engine module 603, otherwise it is discarded; the packets (downlink data) coming from the uplink network interface module 602 enter the switching engine module 603; the data packets coming from the CPU module 604 Enter the switching engine module 603; the switching engine module 603 performs the operation of looking up the address table 606 for the incoming packet to obtain the packet guidance information; if the packet entering the switching engine module 603 is from the downlink network interface to the uplink network interface, then the combination The flow identifier (stream-id) stores the packet in the queue of the corresponding packet buffer 607; if the queue of the packet buffer 607 is close to full, it is discarded; if the packet entering the switching engine module 603 is not a downstream network interface, it is sent to the upstream interface. If the packet goes to the network interface, the data packet is stored in the queue of the corresponding packet buffer 607 according to the packet steering information; if the queue of the packet buffer 607 is close to full, it is discarded.

The switching engine module 603 polls all packet buffer queues. In this embodiment of the present invention, there are two situations:

If the queue goes from the downlink network interface to the uplink network interface, the following conditions are met for forwarding: 1) The send buffer of the port is not full; 2) The packet counter of the queue is greater than zero; 3) The token generated by the code rate control module is obtained ;

If the queue does not go from the downstream network interface to the upstream network interface, the following conditions are met for forwarding: 1) The send buffer of the port is not full; 2) The packet counter of the queue is greater than zero.

The rate control module 608 is configured by the CPU module 604 and generates tokens for the packet buffer queues of all downlink network interfaces going to the uplink network interface within a programmable interval to control the uplink forwarding rate.

The CPU module 604 is mainly responsible for protocol processing with the node server, configuration of the address table 606, and configuration of the code rate control module 608.

Among them, the data packets coming from the downlink network interface module 701 enter the packet detection module 705; the packet detection module 705 detects the Ethernet MAC DA, Ethernet MAC SA, Ethernet length or frame type, video network destination address DA, video network, etc. of the data packet. Whether the source address SA, network data packet type and packet length meet the requirements, if so, a corresponding stream identifier (stream-id) is allocated; then, the MAC deletion module 710 subtracts the MAC DA, MAC SA, length or frame type. (2byte), and enter the corresponding receive buffer, otherwise discard;

The downlink network interface module 701 detects the sending buffer of the port. If there is a packet, it obtains the Ethernet MAC DA of the corresponding terminal according to the visual network destination address DA of the packet, and adds the Ethernet MAC DA of the terminal, the MACSA of the Ethernet protocol conversion gateway, Ethernet length or frame type, and send.

2. Definition of video network data packets

2.1 Access network data packet definition

The data packet of the access network mainly includes the following parts: destination address (DA), source address (SA), reserved bytes, payload (PDU), and CRC.

As shown in the following table, the data packets of the access network mainly include the following parts:

DA SA Reserved Payload CRC

in:

The destination address (DA) consists of 8 bytes. The first byte indicates the type of data packet (such as various protocol packets, multicast data packets, unicast data packets, etc.). There are up to 256 possibilities. The second to sixth bytes are the metropolitan area network address, and the seventh and eighth bytes are the access network address;

The source address (SA) is also composed of 8 bytes and has the same definition as the destination address (DA);

Reserved bytes consist of 2 bytes;

The payload part has different lengths according to different datagram types. If it is a various protocol packet, it is 64 bytes. If it is a single multicast data packet, it is 32+1024=1056 bytes. Of course, it is not limited to The above 2 types;

CRC consists of 4 bytes, and its calculation method follows the standard Ethernet CRC algorithm.

2.2 MAN data packet definition

The topology of the metropolitan area network is a graph. There may be two or even more than two types of connections between two devices, that is, there may be more than two connections between node switches and node servers, node switches and node switches, and node switches and node servers. kind of connection. However, the metropolitan area network address of a metropolitan area network device is unique. In order to accurately describe the connection relationship between metropolitan area network devices, a parameter: label is introduced in the embodiment of the present invention to uniquely describe a metropolitan area network device.

The definition of labels in this manual is similar to the definition of labels in MPLS (Multi-Protocol Label Switch, Multi-Protocol Label Switching). Assuming that there are two connections between device A and device B, then the data packet from device A to device B has 2 labels, the data packet from device B to device A also has 2 labels. Labels are divided into incoming labels and outgoing labels. Assume that the label (incoming label) of a data packet entering device A is 0x0000. The label (outgoing label) of this data packet when it leaves device A may become 0x0001. The network access process of the metropolitan area network is a network access process under centralized control, which means that the address allocation and label allocation of the metropolitan area network are dominated by the metropolitan area server, and the node switches and node servers are only passively executed. It is different from the label allocation of MPLS. The label allocation of MPLS is the result of mutual negotiation between switches and servers.

As shown in the following table, the data packets of the metropolitan area network mainly include the following parts:

DA SA Reserved Label Payload CRC

That is, destination address (DA), source address (SA), reserved bytes (Reserved), label, payload (PDU), and CRC. Among them, the format of the label can refer to the following definition: the label is 32 bits, of which the high 16 bits are reserved and only the low 16 bits are used. Its position is between the reserved bytes of the data packet and the payload.
