Background technique

With the rapid development of network technology, two-way communications such as video conferencing and video teaching are widely used in users' life, work, and study. Therefore, the Internet of View communication technology has gradually become the communication choice of many users.

In the video network, the user terminal needs to pass through the monitoring management platform to retrieve the monitoring video stream, that is, the user terminal sends a request for obtaining the monitoring video stream to the monitoring management platform, and the monitoring management platform returns the monitoring video stream to the user terminal after obtaining the monitoring video stream. In related technologies, the deployment of the monitoring and management platform needs to rely on the IP network, which makes the user terminal need to use the IP access method to obtain the monitoring video stream from the monitoring and management platform. However, when using the IP access method, all video services must be carried out in the video private network, that is: only when the monitoring management platform and the terminal device requesting to monitor the video stream are deployed in the private network, the terminal device can call the monitoring Manage surveillance video streams in the platform. In some remote areas, due to the limited deployment of IP networks, it is impossible to deploy a surveillance management platform, resulting in the inability of terminal devices in this area to retrieve surveillance video streams, which greatly affects the user experience.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

In related technologies, if a user needs to retrieve video streams, he first accesses the monitoring and management server through http://ip:port when accessing, and then controls the video network terminal on the monitoring and management server to retrieve the monitoring. The disadvantage of this method is that if it is in a network isolation area, the ip cannot penetrate, so the monitoring and management server cannot be accessed, and the video cannot be retrieved. In order to overcome this problem, in this embodiment, calling monitoring does not need to access the monitoring management server through ip mode, and it is transmitted through the second layer of the Internet of Vision on the Internet of Vision terminal to solve the problem of network isolation.

Fig. 1 is a schematic diagram of an implementation environment shown by an embodiment of the present application. In this implementation environment, the Internet of Vision terminal communicates with the monitoring management server and the Internet of Vision monitoring access server respectively, and the Internet of Vision terminal, the monitoring management server and the Internet of Vision monitoring access server are all deployed in the Internet of Vision. The monitoring and management server is deployed with a video network monitoring and management system, and the video network monitoring access server stores the monitoring resources of the video network monitoring equipment.

Fig. 2 is a flowchart of a resource scheduling method according to an embodiment of the present application. Referring to Figure 2, the resource scheduling method of the present application may include the following steps:

Step S11: Receive a resource request packet sent by an Internet-of-Vision terminal, where the Internet-of-Vision terminal is any one of all Internet-of-Vision terminals configured in the monitoring and management server.

In this embodiment, multiple monitoring and management servers can be deployed inside the Internet of Things. After each monitoring and management server is connected to the network, it will configure multiple video network terminals on itself. All terminals configured in the monitoring management server can send resource request packets to the monitoring management server. The resource request package is used to request monitoring resources.

Step S12: Based on the Internet of Vision protocol, analyze the resource request packet to obtain resource request parameters.

In this embodiment, the communication and interaction between the monitoring management server and the Internet-of-Vision terminal are all performed based on the Internet-of-Vision protocol. After receiving the resource request packet, the monitoring and management server parses the resource request packet based on the Internet of Vision protocol to obtain resource request parameters. Resource request parameters may include: terminal number, network access number of the monitoring and management server, user ID, number of currently requested pages, resource quantity, etc. The resource request parameters can be set according to actual needs, and this application does not make specific restrictions on this.

Among them, the terminal number is used to uniquely identify the video network terminal in the entire video network; the network access number of the monitoring management server is used to uniquely identify the monitoring management server in the entire video network; the user ID is used to bind multiple monitoring devices (multiple monitoring Devices can be added and removed arbitrarily), and the monitoring management server can obtain the monitoring resources of any monitoring device under it through a certain user ID; after obtaining the monitoring resources, the video network terminal will list the monitoring resources in the form of paging Displayed in the terminal interface, when the user views a certain page of monitoring resource list through the terminal interface, he can request the next page of monitoring resource list from the monitoring management server to obtain more monitoring resources; the number of resources is The number of monitoring resources displayed on a page.

Step S13: Obtain a list of monitored resources according to the resource request parameters.

In this embodiment, the parameters used when obtaining the monitoring resource list are mainly: user ID. According to the user ID, the monitoring management server obtains corresponding monitoring resources from multiple monitoring devices bound to the user ID

Step S14: Encapsulating the monitoring resource list based on the Internet of Vision protocol to obtain a resource response packet.

In this embodiment, after obtaining the monitoring resource list, the monitoring management server encapsulates the monitoring resource list based on the Internet of View protocol to obtain a resource response packet.

Step S15: sending the resource response packet as a response packet of the resource request packet to the Internet-of-Video terminal.

In this embodiment, after obtaining the resource response packet, the monitoring management server sends the resource response packet to the Internet of Vision terminal, so that the Internet of Vision terminal parses the resource response packet, obtains a list of monitoring resources, and displays it on the interface of the Internet of Vision terminal.

Exemplarily, taking the monitoring and management server A in the Internet of Vision as an example, it is assumed that the monitoring and management server A has completed the configuration of the terminals 1-N of the Internet of Vision by itself. When the monitoring and management server A receives the resource request packet sent by the Internet of Vision terminal 1, it analyzes the resource request packet according to the Internet of Vision protocol, and obtains the terminal number of the Internet of Vision terminal 1, the network access number of the monitoring and management server, user ID, current The number of pages requested, the number of resources, etc., the monitoring management server A checks that the network access number of the monitoring management server is the same as the network access number assigned when it is connected to the network, and determines that the video network terminal 1 is requesting monitoring resources from itself, according to the video network terminal 1 terminal number, in the pre-stored multiple terminal number-user ID list, find the user ID corresponding to the Internet of Vision terminal 1, and obtain monitoring resources from multiple monitoring devices bound to the user ID, according to the current request The number of pages, determine the monitoring resources in the number of pages requested by the user, obtain the monitoring resources that meet the number of resources from the remaining monitoring resources, and then generate a list of monitoring resources, and then use the Internet of Things protocol to encapsulate the list of monitoring resources , to obtain a resource response packet, and finally transmit the resource response packet to the Internet of Vision terminal 1 through the Internet of Vision transparent transmission method, so as to respond to the resource request packet sent by the Internet of Vision terminal 1, thereby completing the scheduling of monitoring resources.

In the embodiment of this application, the monitoring and management server is deployed in the Internet of Vision, as long as it is a terminal device deployed in the Internet of Vision, that is, a terminal of the Internet of Vision, the monitoring and management server can configure it in itself, and receive its information later. The resource request packet sent. After receiving the resource request packet sent by the Internet of Vision terminal, the monitoring and management server analyzes the resource request packet based on the Internet of Vision protocol, obtains the resource request parameters, and obtains the list of monitoring resources according to the resource request parameters, and then according to the Internet of Vision protocol. The monitoring resource list is encapsulated to obtain a resource response packet, and finally the resource response packet is sent to the Internet of Vision terminal as a response packet of the resource request packet. In this embodiment, multiple monitoring and management servers can be deployed in the Internet of Views, and the Internet of Views terminal can be configured in any monitoring and management server, so it can request monitoring resources from any configured monitoring and management server without being subject to dedicated Network/LAN restrictions, compared to related technologies, when a video network terminal requests monitoring resources in the monitoring management server through IP, the video network terminal can only request monitoring resources from the monitoring management server deployed in the video private network where it is located , the monitoring resource scheduling process of this application is completely based on the Internet of View method, and the method of requesting monitoring resources is more flexible, which can not only give full play to the value of massive monitoring resources in actual business, but also provide great convenience for users to view monitoring resources, effectively improving User experience.

In combination with the above embodiments, in one implementation manner, before receiving the resource request packet sent by the Internet-of-Vision terminal, the monitoring and management server needs to configure multiple Internet-of-Vision terminals on itself. Specifically, the resource scheduling method of the present application may also include:

Obtaining a terminal number of at least one Internet-of-Video terminal, and storing the terminal number;

For each of the terminal numbers, a user ID is assigned, and the user ID is bound to at least one monitoring device in the Internet of Vision;

Sending the network access number of the monitoring and management server to each of the video networking terminals, and the user ID assigned to the video networking terminal, so that the video networking terminal stores the network access number and the user ID of the monitoring and management server, And when it is necessary to request monitoring resources from the monitoring management server, generate the resource request packet according to the network access number and the user ID, and the network access number of the monitoring management server is used to uniquely identify the monitoring management server;

Correspondingly, the resource request packet is parsed to obtain resource request parameters, including:

Analyzing the resource request packet to obtain the network access number of the monitoring and management server and the user ID;

Correspondingly, according to the resource request parameters, obtain a monitoring resource list, including:

When the network access number of the monitoring management server is the same as its own network access number, the monitoring resource list is obtained according to the user ID.

In this embodiment, the monitoring and management server can configure any Internet-of-Vision terminal on itself, and provide Internet-of-Vision services for successfully configured Internet-of-Vision terminals. The specific configuration process is as follows: the monitoring and management server first completes the network access; after the network access is successful, it obtains multiple valid terminal numbers of the Internet of View terminals, and the acquisition method can be obtained from a third-party platform or manually entered. Not specifically limited; then obtain a plurality of user IDs, wherein the acquisition method can be obtained from the monitoring access server; then assign a plurality of user IDs to a plurality of video network terminals, so that each video network terminal corresponds to a user ID, Since the monitoring devices bound under different user IDs can be different, therefore, by assigning different user IDs to the Internet-of-Vision terminals, the monitoring resources obtained by the Internet-of-Vision terminals can be controlled; after the allocation of multiple user IDs is completed, the Each video network terminal sends its assigned user ID and the network access number of the monitoring management server itself; after receiving the user ID and the network access number of the monitoring management server, the video network terminal returns a response, and the monitoring management server receives the response After that, it is determined that the Internet-of-Sight terminal is configured successfully. After the Internet-of-Vision terminal is successfully configured, when it is necessary to request monitoring resources from the monitoring management server, a resource request packet can be generated based on the user ID and the network access number of the monitoring management server and sent to the monitoring management server. The specific process can be referred to above. , the present application does not specifically limit this.

In this embodiment, since multiple monitoring and management servers can be deployed in the Internet of Views, multiple Internet of Viewing terminals can be configured in each monitoring and management server, so that the same Internet of Viewing terminal may be configured in multiple monitoring and management servers. Hence the phenomenon of having multiple user IDs. When the resource scheduling method of the present application is actually implemented, the configuration coverage principle is adopted, that is, after receiving the user ID and the network access number of the monitoring management server sent by the monitoring and management server, the video network terminal uses the user ID and the monitoring and management server's The network access number overwrites the user ID sent by the previous monitoring and management server and the network access number of the monitoring and management server, so that only the user ID and the network access number of the monitoring and management server sent by one monitoring and management server are saved. Certainly, the Internet-of-view terminal may also save the user ID sent by each monitoring and management server and the network access number of the monitoring and management server without adopting the principle of configuration coverage. A monitoring management server is selected among the monitoring management servers, and a resource request packet is generated according to the user ID and network access number sent by it, and then monitoring resources are obtained. The specific method used by the Internet-connected terminal to store the user ID and the network access number of the monitoring and management server can be set according to actual needs, and this application does not make specific restrictions on this.

With reference to the above embodiments, in an implementation manner, it is also possible to set monitoring resource acquisition permissions for each Internet-of-Vision terminal. Specifically, the resource scheduling method of the present application may also include:

Set resource permissions for each user ID corresponding to the terminal number, and the resource permissions are permissions for the Internet-of-Video terminal to request monitoring resources under the user ID;

Correspondingly, obtaining the monitoring resource list according to the user ID includes:

Obtain resource permissions for the user ID;

The monitoring resource list is obtained according to the resource authority.

In this embodiment, since each user ID is bound with multiple monitoring devices, by controlling the monitoring devices under the user ID, it is possible to further control the monitoring resources acquired by the Internet-of-Vision terminal. For example, when the user ID: YTY58 is assigned to the Internet-of-Vision terminal A, the bound monitoring devices can be set under the user ID: YTY58 to be the monitoring devices in area A and area B, so that the Internet-of-vision terminal A can only obtain To the monitoring resources collected by the monitoring devices in area A and area B.

In this embodiment, the monitoring and management server may set the resource authority for each Internet-of-Vision terminal during the process of configuring the Internet-of-Vision terminal, or may set the resource authority for each Internet-of-Vision terminal after the configuration is completed. After the resource permission is set, the available monitoring resources of the Internet of Vision terminal can be pre-stored according to the resource permission, so that the monitoring resource can be returned to the Internet of Vision terminal in time when the Internet of Vision terminal requests the monitoring resource next time.

In this embodiment, the monitoring resources pre-stored in the monitoring management server mainly include: monitoring name, monitoring ID, organizational structure, online status, and inspection faults. When the Internet of Vision terminal requests monitoring resources next time, the monitoring management server can return such monitoring resources to the Internet of Vision terminal, so that the Internet of Vision terminal can select the target monitoring resource, obtain the target monitoring resource from the monitoring access server, and monitor the access server. It is mainly used to store surveillance video streams corresponding to surveillance resources.

In combination with the above embodiments, in an implementation manner, a paging transmission mechanism may also be adopted to return the monitoring resource to the Internet-of-Vision terminal. Specifically, the resource request parameters include: the number of currently requested pages and the number of resources.

Therefore, according to the resource request parameters, the monitoring resource list can be obtained as follows:

Determine the number of requested pages and the corresponding sent monitoring resources according to the number of currently requested pages;

determining the unsent monitoring resources according to the sent monitoring resources;

Obtain monitoring resources that match the number of resources from unsent monitoring resources as a list of monitoring resources corresponding to the number of currently requested pages.

In this embodiment, the monitoring and management server can return the monitoring resource to the Internet-of-Vision terminal in a paged transmission manner. The Internet-of-Sight terminal displays the monitoring resources in the form of a list and pages in the terminal interface for users to view. When the user views the list of monitoring resources on a certain page, if he needs to continue to view the monitoring resources on the next page, he can set the number of pages currently requested and the number of resources. In the request packet, it is sent to the monitoring and management server.

For example, take the user viewing the monitoring resources on the video network terminal A as an example. If the user has already viewed the monitoring resources on the third page and wants to request the monitoring resources on the fourth page, set the number of currently requested pages to 4, and set the The number of monitoring resources displayed on page 4 is, for example, 10. After obtaining the 4th and 10 items entered by the user, the Internet-of-Sight terminal A encapsulates the value into a resource request packet, and sends the resource request packet to the monitoring management server ; The monitoring management server analyzes and obtains that the user wants to request the monitoring resources on page 4, obtains the monitoring resources on pages 1-3, and removes the monitoring resources on pages 1-3 from the pre-stored monitoring resources that can be obtained by the Internet-of-Vision terminal A Resources, obtain 10 monitoring resources from the remaining monitoring resources, as the monitoring resources displayed on page 4.

In this embodiment, monitoring resources are displayed in a page-by-page manner, which can respond to users' requests for obtaining monitoring resources in a timely manner. At the same time, it provides users with a variety of monitoring resource request methods, meets user needs, and improves user experience.

In combination with the above embodiments, in one implementation manner, based on the Internet of Vision protocol, the monitoring resource list is encapsulated to obtain a resource response packet, which may include:

Based on the Internet of View protocol, the monitoring resource list is encapsulated in the form of a json character string to obtain the resource response packet;

Correspondingly, sending the resource response packet as a response packet of the resource request packet to the Internet-of-Video terminal includes:

Transmitting the resource response packet as a response packet of the resource request packet to the Internet-of-Video terminal;

When the transparent transmission fails, the resource response packet is transparently transmitted to the Internet-of-Video terminal again until the transparent transmission succeeds.

In this embodiment, after the monitoring management server obtains monitoring resources (in each embodiment of the application, if not specified, the monitoring resources in the monitoring management server are all stored in the form of a list), based on the Internet of View protocol, Encapsulate the monitoring resource according to the json string, get the resource response package, and transparently transmit the resource response package to the networked terminal through the Internet of View transparent transmission method, and when the transparent transmission fails, transparently transmit it again until the resource response The packet is successfully transparently transmitted to the Internet of Vision terminal.

The present application also provides a resource scheduling method, which is applied to the Internet-of-Vision terminal in FIG. 1 . Fig. 3 is a flowchart of another resource scheduling method according to an embodiment of the present application. Referring to FIG. 3, the resource scheduling method of the present application may include:

Step S21: Obtain resource request parameters input by the user;

Step S22: Determine the target monitoring and management server according to the resource request parameters;

Step S23: Encapsulating the resource request parameters based on the Internet of View protocol to obtain a resource request packet;

Step S24: Send the resource request packet to the target monitoring and management server, and the target monitoring and management server is any monitoring and management server among at least one monitoring and management server deployed in the Internet of Vision;

Step S25: Receive a resource response packet for the resource request packet returned by the target monitoring and management server.

In the embodiment of the present application, the Internet-of-Vision terminal is mainly used to display monitoring resources, and of course, can also be used to receive resource request parameters input by users. For example: the user can input the number of currently requested pages, the number of resources, and the network access number of the monitoring management server on the Internet-of-view terminal (when the network access number of multiple monitoring management servers is stored by itself, the input number of the monitoring management server can be selected )Wait.

Determining the target monitoring and management server according to the resource request parameters mainly refers to: determining the target monitoring and management server according to the network access number of the monitoring and management server. In this embodiment, the user does not have to input all resource request parameters. When the Internet-of-Vision terminal only stores the network access number of a monitoring and management server and the assigned user ID, the user only needs to input the number of currently requested pages and the number of resources. , the video network terminal automatically encapsulates the resource request package according to the stored network access number of the monitoring management server, the assigned user ID, the number of pages currently requested, the number of resources, and the terminal number; when the video network terminal only stores multiple monitoring management For the network access number of the server and the assigned user ID, the user only needs to enter the network access number of the target monitoring and management server, the number of pages currently requested, and the number of resources, and the networked terminal will monitor and manage the server according to the stored network access number and assigned user ID. 1. Input the current request page number, resource quantity and terminal number, etc., encapsulate the resource request packet, send the resource request packet to the monitoring and management server, and receive the returned resource response packet.

In combination with the above embodiments, in one implementation manner, after receiving the resource response packet for the resource request packet returned by the monitoring and management server, the following steps may also be performed:

Analyzing the resource response packet based on the Internet of View protocol to obtain a list of monitoring resources;

displaying the list of monitoring resources;

receiving a request for on-demand target monitoring resources sent by the remote control terminal, where the target monitoring resources are any monitoring resources determined by the user in the monitoring resource list;

Send the request to the Internet of View monitoring access server;

receiving the target monitoring resource returned by the Internet of View monitoring access server;

Play the target monitoring resource.

In this embodiment, after receiving the resource response packet, the video network terminal parses the resource response packet to obtain a monitoring resource list, and displays the monitoring resource list on the terminal interface for users to view.

In this embodiment, the video network terminal also has a matching remote control terminal. The user inputs operation instructions through the remote control terminal, for example: select the target monitoring resource in the monitoring resource list displayed on the terminal interface through the remote control terminal, and the remote control terminal generates a request for on-demand target monitoring resource according to the user's operation, and sends it to the Internet of View terminal, and the Internet of View The terminal sends the request to the Internet of View monitoring access server, and the Internet of View monitoring access server obtains the target monitoring resources from the massive monitoring resources stored in the Internet of Viewing server, and sends the target monitoring resources to the Internet of Viewing terminal, and the Internet of Viewing terminal is displayed in the terminal interface Play target monitoring resources to meet the viewing needs of users.

Fig. 4 is a schematic diagram of a resource scheduling method according to an embodiment of the present application. When using the resource scheduling method of the present application, the Internet-of-Vision monitoring and management platform (ie: the Internet-of-Vision monitoring and management system) first completes the configuration of the Internet-of-Vision terminals by itself, and binds resource permissions for each Internet-of-Vision terminal (the step of setting resource permissions For details, please refer to the previous description); after the configuration is completed, when the Internet of Vision terminal requests monitoring information from the Internet of Vision monitoring and management platform, the Internet of Vision monitoring and management platform will transparently transmit the obtained monitoring information to the Internet of Vision terminal according to the Internet of Vision protocol, The video network terminal displays the monitoring information on the terminal interface, determines the monitoring to be played according to the user's choice, and then sends a video stream scheduling request to the video network monitoring access server, and the video network monitoring access server responds to the request and sends a video stream to the video network terminal Returns the surveillance video stream to be played.

In the above process, the Internet of Vision protocols used interactively between the Internet of Vision monitoring and management platform and the Internet of Vision terminals include: 6101 protocol and 6102 protocol. The resource scheduling method of the present application will be described as a whole below with reference to FIG. 1 .

To send monitoring information, the Internet-of-Vision monitoring access server communicates with the Internet-of-Vision monitoring management system and each Internet-of-Vision terminal for sending monitoring information (for example: monitoring name, monitoring ID, organization, online status) to the Internet-of-Vision monitoring and management system and information such as inspection faults), and send monitoring video streams to each Internet-of-Vision terminal.

Assuming that the Internet-of-Vision terminal A needs to request monitoring resources from the Internet-of-Vision monitoring and management system, it first sends an instruction to the Internet-of-Vision monitoring and management system whether it can currently request monitoring resources. The protocol generates a transparent transmission command sequence and returns it to the Internet of Vision terminal to inform the terminal that it can request monitoring resources at present.

The Internet of Vision service recovery method provided by this application is applied to the Internet of Vision. The following will briefly introduce the Internet of Vision technology:

The Internet of Vision is an important milestone in the development of the network. It is a real-time network that can realize real-time transmission of high-definition video, and push many Internet applications to high-definition video, high-definition face-to-face.

The Internet of View adopts real-time high-definition video exchange technology, which can provide required services on one network platform, such as high-definition video conferencing, video surveillance, intelligent monitoring and analysis, emergency command, digital broadcast TV, time-lapse TV, online teaching, live broadcast , VOD on demand, TV mail, personalized recording (PVR), intranet (self-managed) channel, intelligent video broadcast control, information release and other dozens of video, voice, picture, text, communication, data and other services are all integrated in one System platform, realize high-definition quality video playback through TV or computer.

In order to enable those skilled in the art to better understand the embodiments of the present invention, the Internet of Things is introduced as follows:

Some of the technologies applied in the Internet of Things are as follows:

Network Technology

The network technology innovation of the Internet of View has improved the traditional Ethernet (Ethernet) to face the potentially huge video traffic on the network. Different from pure network packet switching (Packet Switching) or network circuit switching (Circuit Switching), video networking technology uses Packet Switching to meet Streaming requirements. The Internet of Vision technology has the flexibility, simplicity and low price of packet switching, and at the same time has the quality and security guarantee of circuit switching, realizing the seamless connection of switched virtual circuits and data formats throughout the network.

Switching Technology

Video networking adopts the two advantages of Ethernet asynchronous and packet switching, eliminates the defects of Ethernet under the premise of full compatibility, has end-to-end seamless connection of the whole network, directly connects to user terminals, and directly carries IP data packets. User data does not require any format conversion within the entire network. Video networking is a more advanced form of Ethernet. It is a real-time switching platform, which can realize the real-time transmission of large-scale high-definition video in the whole network that cannot be realized by the Internet at present, and push many network video applications to high-definition and unification.

Server Technology

The server technology on the Internet of View and unified video platform is different from the server in the traditional sense. Its streaming media transmission is based on connection-oriented, and its data processing capability has nothing to do with traffic and communication time. A single network layer can contain information command and data transmission. For voice and video services, the complexity of video streaming and unified video platform streaming media processing is much simpler than data processing, and the efficiency is greatly improved by more than 100 times compared with traditional servers.

Storage Technology

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

Network Security Technology

The structural design of the Internet of View completely eradicates the network security problems that plague the Internet through the individual licensing system for each service, complete isolation of equipment and user data, and generally does not require anti-virus programs and firewalls, preventing hackers and virus attacks , to provide users with a structured worry-free security network.

Service Innovation Technology

The unified video platform integrates business and transmission together, whether it is a single user, a private network user or the sum of a network, it is just an automatic connection. User terminals, set-top boxes or PCs are directly connected to the unified video platform to obtain rich and colorful multimedia video services in various forms. The unified video platform adopts the "recipe-style" table matching mode to replace the traditional complex application programming. It can realize complex applications with very little code and realize "unlimited" new business innovations.

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

Similarly, the devices in the MAN part can also be divided into three categories: MAN servers, node switches, and node servers. The metro server is connected to the node switch, and the node switch can be connected to multiple node servers.

Wherein, 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, which can control node switches and node servers. The metro server can be directly connected to the node switch, or directly connected to the node server.

It can be seen that the entire Vision Network is a layered centralized control network structure, while the network controlled by the node server and the metro server can be in various structures such as tree, star, and ring.

Vividly speaking, 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 the metropolitan area and the wide area video network.

2. Definition of Internet of Vision data package

2.1 Definition of Access Network Packet

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 table below, 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 (byte), 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 byte to the sixth byte is the address of the metropolitan area network, and the seventh and eighth bytes are the address of the access network;

The source address (SA) is also composed of 8 bytes (byte), and the definition is the same as that of 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 variety of protocol packets, 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 Above 2 types;

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

2.2 MAN 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 2 connections between node switches and node servers, node switches and node switches, and node switches and node servers. kind of connection. However, the MAN address of the MAN device is unique. In order to accurately describe the connection relationship between MAN devices, a parameter: label is introduced in the embodiment of the present invention to uniquely describe a MAN 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 packets from device A to device B have 2 labels, the packet from device B to device A also has 2 labels. The label is divided into an incoming label and an outgoing label. Assuming that the label (incoming label) of the data packet entering device A is 0x0000, the label (outgoing label) of the 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 all dominated by the metropolitan area server, and the node switches and node servers are all passively executed. Different from MPLS label allocation, MPLS label allocation is the result of mutual negotiation between switches and servers.

As shown in the table below, the data packet of the MAN mainly includes the following parts:

DA SA Reserved Label Payload CRC

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