Description

Network collaboration method, device, equipment and storage medium

Technical Field

The present application relates to the field of communications, and in particular to a network collaboration method, apparatus, device and storage medium.

Background technique

The backbone network generally consists of two parts: the IP layer network and the optical layer network. The IP layer network is responsible for data grouping and forwarding; the optical layer network is responsible for large-capacity, ultra-long-distance data transmission and provides optical channels for the IP layer network.

Currently, the two networks are hierarchically planned and independently operated and maintained. The IP layer network cannot know the network topology and protection capabilities of the optical layer network, and the optical layer network cannot understand the dynamic business needs of the IP layer network. There is no real collaboration between the two, which makes it impossible to build a high-performance, low-cost backbone network. In the future, optical transport network (OTN) equipment based on optical service unit (OSU) should support automatic connection driven by traffic to achieve efficient collaboration between IP layer network and optical layer network.

As a physical bearer network, the traditional optical transport network OTN can support transparent transmission of customer signals, high-bandwidth multiplexing switching and configuration, and has strong overhead support capabilities. This technology is mainly positioned in backbone network and metropolitan area network applications, and is used to carry services with a rate greater than 1Gbits/s. After OTN is sunk to the metropolitan area/access network, the following problems exist: insufficient pipeline elasticity (minimum pipeline ODU0), small number of connections, and insufficient flexibility in bandwidth adjustment. The industry has proposed the concept of optical service network, defined the service-oriented OSU container standard, and adopted a more flexible pipeline bandwidth definition, which can more efficiently carry small-granular signal services, realize service-oriented optical bearer technology, and promote the development of all-optical service networks.

The service-aware optical network based on OSU provides technical support for the flexible connection of service transmission paths and the efficient use of resources, but it also brings new challenges to the management of networks and services: with the development of small-granularity OSU technology, the number of connections carried by optical layer networks in the future will increase dramatically, which will bring severe challenges to network operation and maintenance. Therefore, it is necessary to automatically establish optical transport network (such as OSU) connections based on IP layer network traffic information, realize traffic-aware automatic connection management, and then realize efficient collaboration between IP layer network and optical layer network.

Based on this, an embodiment of the present application provides a network collaboration method, which constructs a correspondence between the OSU device of the optical layer network and the router of the IP layer network, and synchronizes the correspondence between the OSU device of the optical layer network and the router of the IP layer network to all OSU devices in the optical layer network, so that when the source router of the IP layer network sends data to the destination router, it can obtain the communication address of the OSU device connected to the destination router according to the correspondence stored in the OSU device connected to the source router, and then automatically establish a connection with the OSU device connected to the destination router according to the communication address of the OSU device connected to the destination router, and plan the shortest data transmission path, so as to quickly transmit data, improve the data transmission rate, and realize efficient collaboration between the IP layer network and the optical layer network.

Fig. 1 is a schematic diagram of the structure of a communication system provided by the present application according to an exemplary embodiment. As shown in Fig. 1, the communication system 10 includes M OSU devices (e.g., OSU device 111, OSU device 112, OSU device 113, OSU device 114, and OSU device 115) and N routers (e.g., router 121, router 122, router 123, router 124, and router 125), where M and N are both integers.

In some embodiments, each OSU device is connected to a router, for example, OSU device 111 is connected to router 121 , OSU device 112 is connected to router 122 , OSU device 113 is connected to router 123 , OSU device 114 is connected to router 124 , and OSU device 115 is connected to router 125 .

For each of the M OSU devices, an OSU device can be connected to other OSU devices in the communication network. For example, OSU device 111 can be connected to OSU device 112, OSU device 113 and OSU device 115 respectively, OSU device 112 can be connected to OSU device 115, OSU device 113 can be connected to OSU device 114, and OSU device 114 can be connected to OSU device 115.

In some embodiments, the OSU device is a technical improvement made to address the technical shortcomings of traditional OTN technology. It changes the characteristics of the traditional OTN frame structure divided by time slots and adopts a more flexible payload block division method. It can achieve efficient carrying of services with different granularities of 2M-100Gbps and support k-level connections. The simplified bandwidth lossless adjustment mechanism can well meet the customer's demand for flexible and variable service bandwidth.

In some embodiments, the communication network also includes an address allocation device, which may be an independent physical device, such as a server or a computer. The server may be a single server, or a server cluster consisting of multiple servers. In some implementations, the server cluster may also be a distributed cluster, and the embodiments of the present application do not limit the specific type of the address allocation device.

In some embodiments, the address allocation device is used to allocate communication addresses to M OSU devices in the communication network.

It should be understood that Fig. 1 is an exemplary architecture diagram, and the number of devices included in the communication system shown in Fig. 1 is not limited. In addition, in addition to the devices shown in Fig. 1, the communication system shown in Fig. 1 may also include other devices, which is not limited.

As shown in FIG. 2 , a flowchart of a network collaboration method is provided for an embodiment of the present application. The method is executed by a first OSU device. The first OSU device may be any one of the M OSU devices included in the communication network 10 shown in FIG. 1 . For example, the first OSU device may be an OSU device 111. The method includes the following steps:

S101. Acquire a communication address of a first OSU device, and acquire a network address of a first router from a first router to which the first OSU device is connected.

It should be noted that when an OSU device joins a communication network, it needs to obtain its own communication address and the network address of the router connected to it, so as to establish a correspondence between its own communication address and the network address of the router connected to it.

Optionally, the OSU device establishes the correspondence between its own communication address and the network address of the router to which it is connected by receiving information input by the operation and maintenance personnel of the communication network, and establishing the correspondence between its own communication address and the network address of the router to which it is connected according to the information input by the operation and maintenance personnel. Alternatively, the OSU device may automatically establish the correspondence between its own communication address and the network address of the router to which it is connected after obtaining its own communication address based on an autonomous learning algorithm based on artificial intelligence.

It should be noted that if the information input by the operation and maintenance personnel is received to establish the correspondence between the communication address of the OSU device and the network address of the router connected to the OSU device, the operation and maintenance personnel are required to manually assign the communication address of each OSU device, which may easily cause a large workload for the operation and maintenance personnel. Taking into account the complexity of operation and maintenance, an autonomous learning method based on artificial intelligence can be adopted in the embodiment of the present application to enable the OSU device to automatically establish the correspondence between the communication address of the OSU device and the network address of the router connected to the OSU device.

In some embodiments, when the first OSU device adopts an artificial intelligence-based autonomous learning method to automatically establish a correspondence between its own communication address and the network address of the router to which it is connected, the first OSU device can obtain its own communication address from the address allocation device. Regarding how the first OSU device obtains its own communication address from the address allocation device, please refer to the following description of steps S301-S304, which will not be repeated here.

In some embodiments, the first OSU device may send a sixth request message to a first router connected to the first OSU device, the sixth request message being used to request a network address of the first router, and then the first OSU device receives a third response message sent by the first router, the third response message including the network address of the first router. The network address of the first router may be an IP address of the first router or virtual local area network (VLAN) information, etc.

S102: Establish a correspondence between the communication address of the first OSU device and the network address of the first router.

Exemplarily, assuming that the communication address of the first OSU device is OSU-UUID-A and the network address of the first router is Net-1, the correspondence between the communication address of the first OSU device and the network address of the first router can be as shown in Table 1 below.

Table 1

Serial number Communication address of OSU device The network address of the router 1 OSU-UUID-A Net-1

S103: Synchronize the correspondence between the communication address of the first OSU device and the network address of the first router to other OSU devices in the communication network.

Optionally, step S103 can be specifically implemented as: sending a fifth request message to other OSU devices, the fifth request message including the correspondence between the communication address of the first OSU device and the network address of the first router, and the fifth request message is used to request other OSU devices to store the correspondence between the communication address of the first OSU device and the network address of the first router.

In some embodiments, if other OSU devices agree to store the correspondence between the communication address of the first OSU device and the network address of the first router, then after the other OSU devices store the correspondence between the communication address of the first OSU device and the network address of the first router, the first OSU device receives a fifth response message sent by each of the other OSU devices, and the fifth response message is used to indicate that the correspondence between the communication address of the first OSU device and the network address of the first router has been agreed and stored.

After the first OSU device receives the fifth response information sent by each of the other OSU devices, it stores the correspondence between the communication address of the first OSU device and the network address of the first router in response to the fifth response information. In this way, the M OSU devices in the communication network all synchronously store the correspondence between the communication address of the first OSU device and the network address of the first router.

Based on the embodiment shown in FIG. 2 , it can be known from the above introduction about the first OSU device that the first OSU device can be any one of the M OSU devices, that is, when each OSU device joins the communication network, it is necessary to execute the above steps S101 to S103, that is, when each OSU device establishes a corresponding relationship between its own communication address and the network address of the router connected to itself, it is necessary to synchronize the corresponding relationship to other OSU devices in the communication network. In this way, the OSU devices in the communication network all store the corresponding relationship between the communication address of each OSU device and the network address of the router connected thereto, so that when a router connected to an OSU device needs to transmit data to a destination router, it can quickly find the communication address of the OSU device connected to the destination router according to the corresponding relationship between the OSU device and the router of the communication network stored by the OSU device connected thereto, and then automatically establish a connection with the OSU device and determine the shortest path for transmitting data, and then quickly transmit the data, which can improve the data transmission rate and realize the efficient collaborative work of the IP layer network and the optical layer network.

The above embodiment focuses on the process of establishing the correspondence between the communication address of the OSU device and the network address of the router, and after the correspondence between the communication address of the OSU device and the network address of the router is established, it also includes the process of using the correspondence between the communication address of the OSU device and the network address of the router. In some embodiments, as shown in FIG3, the network collaboration method further includes the following steps:

S201: Receive first request information sent by a first router.

In some embodiments, when a first router (also referred to as a source router) needs to transmit a data packet to a second router (also referred to as a destination router), a first OSU device receives a first request message sent by the first router, and the first request message is used to request a communication address of a second OSU device connected to the second router. The first request message includes a network address of the second router, such as an IP address of the second router.

Optionally, the first request information may also include the IP address of the first router, the port number of the first router, the port number of the second router, the third layer protocol type, the sampling ratio of the port, the receiving timestamp of the first request information and the transmission control protocol (TCP) sequence number, etc.

S202: According to the network address of the second router, determine whether a corresponding relationship related to the network address of the second router is stored in the system.

The corresponding relationship related to the network address of the second router may be a corresponding relationship between the network address of the second router and the communication address of the second OSU device. It can be known from the above step S101 that the second OSU device is an OSU device connected to the second router.

Exemplarily, as shown in the following Table 2, the correspondence between the communication address of the OSU device stored in the first OSU device and the network address of the router.

Table 2

Serial number Communication address of OSU device The network address of the router 1 OSU-UUID-A Net-1 2 OSU-UUID-C Net-5 3 OSU-UUID-D Net-9 4 OSU-UUID-E Net-4 5 OSU-UUID-F Net-3 6 OSU-UUID-X Net-6

The first OSU device may use the network address of the second router as an index, traverse its own database, and determine whether it has stored a corresponding relationship related to the network address of the second router.

If not, execute the following steps S203 to S205.

If yes, execute the following step S206.

S203: If the corresponding relationship related to the network address of the second router is not stored in the OSU device, send a second request message including the network address of the second router to other OSU devices.

If the corresponding relationship related to the network address of the second router is not found in its own database based on the network address of the second router as an index, it is determined that the corresponding relationship related to the network address of the second router is not stored in its own database, and the first OSU device can send a second request information including the network address of the second router to other OSU devices, wherein the second request information is used to request the communication address of the second OSU device connected to the second router.

Exemplarily, assuming that the network address of the second router is Net-7, Net-7 is used as the index to traverse the above Table 2, and no corresponding relationship related to Net-7 is found, that is, it is determined that the first OSU device does not store the corresponding relationship related to the network address of the second router.

It is understandable that if its own database does not store the corresponding relationship related to the network address of the second router, it may be that the first OSU device joined the communication network late, resulting in the correspondence between the communication address of the second OSU device and the network address of the second router not being synchronized to the database of the first OSU device. In this case, the first OSU device can send a second request message to other OSU devices to obtain the communication address of the second OSU device connected to the second router.

S204: Receive first response information sent by the third OSU device.

The first response information includes a corresponding relationship related to the network address of the second router, and the third OSU device is any one of the other OSU devices.

It can be understood that after the other OSU devices receive the second request information sent by the first OSU device, the other OSU devices can determine whether they have stored the corresponding relationship related to the network address of the second router according to the network address of the second router included in the second request information. If they have stored the corresponding relationship related to the network address of the second router, they send the first response information to the first OSU device.

S205: Send the corresponding relationship related to the network address of the second router to the first router.

It should be understood that sending the corresponding relationship related to the network address of the second router to the first router, that is, sending the communication address of the second OSU device connected to the second router to the first router, so that the first router can determine the shortest transmission path between the second OSU device according to the communication address of the second OSU device, automatically establish a connection with the second OSU device, and then transmit data packets to the second OSU device, can reduce the time consumed by the first router to establish a connection with the second OSU device, that is, can improve the transmission efficiency of data packets, and realize efficient collaboration between the IP layer network and the optical layer network.

Furthermore, while sending the corresponding relationship related to the network address of the second router to the first router, the first OSU device can store the corresponding relationship related to the network address of the second router, that is, supplement and update in real time the corresponding relationship between the communication address of the OSU device in the communication network and the network address of the router stored by the first OSU itself, so that when the first router transmits data to the second router again, it can quickly establish a connection with the second OSU device according to the updated corresponding relationship, thereby improving the rate at which the first router establishes a connection with the second OSU device and improving the transmission efficiency of data packets.

S206: If the corresponding relationship related to the network address of the second router is stored in the first router, the corresponding relationship related to the network address of the second router is sent to the first router.

If the first OSU device itself stores a corresponding relationship related to the network address of the second router, it means that the first OSU device stores the communication address of the second OSU device connected to the second router, and the first OSU device can send the communication address of the second OSU device to the first router.

Exemplarily, if the network address of the second router is Net-5, then traverse the above Table 2 according to Net-5 to determine that the corresponding relationship related to the network address of the second router is stored in itself, and the communication address of the second OSU device that has a corresponding relationship with the network address Net-5 of the second router is OSU-UUID-C, then the first OSU device sends the communication address OSU-UUID-C of the second OSU device to the second router.

In some embodiments, as shown in FIG. 4 , the acquisition of the communication address of the first OSU device in the above step S101 may be specifically implemented as the following steps S301 to S304 .

S301: Receive a first communication address allocated to a first OSU device and sent by an address allocation device in a broadcast manner.

In some embodiments, when an OSU device joins a communication network, it can send a discover broadcast message to the communication network to discover the address allocation device in the communication network. After the address allocation device receives the discover broadcast message, it can send the first communication address allocated to the first OSU device to the first OSU device by broadcasting according to the usage of its own address resource pool. Then, the first OSU device receives the first communication address sent by the address allocation device.

S302: Send third request information to the address allocation device.

After the first OSU device receives the first communication address sent by the address allocation device, the first OSU device may send third request information including the first communication address to the address allocation device, wherein the third request information is used to request the address allocation device to determine whether the first communication address has been allocated.

It can be understood that since the address allocation device sends the first communication address allocated to the first OSU device to the first OSU device in the form of broadcast, other OSU devices in the communication network can also receive the first communication address. If there is an OSU device that is also a newly added OSU device to the communication network, then this OSU device may also use the first communication address as the communication address allocated to it by the address allocation device. Therefore, after the first OSU device receives the first communication address sent by the address allocation device, the first OSU device can send a third request information including the first communication address to the address allocation device to request the address allocation device to determine whether the first communication address has been allocated to other OSU devices.

S303: If confirmation information of non-allocation sent by the address allocation device is received, an address resolution request including the first communication address is sent to other OSU devices.

In some embodiments, if the address allocation device receives the third request information sent by the first OSU device and determines that the first communication address has been allocated, the address allocation device still sends the reallocated communication address to the first OSU device in a broadcast form.

In some embodiments, if the address allocation device determines that the first communication address is not allocated, the first OSU device receives confirmation of non-allocation information sent by the address allocation device, and then the first OSU device determines that the first communication address is not allocated according to the confirmation of non-allocation information.

Optionally, after the first OSU device determines that the first communication address is not allocated, in order to improve the accuracy of confirming that the first communication address is not allocated, the first OSU device may send an address resolution request including the first communication address to other OSU devices, and the address resolution request is used to request other OSU devices to determine whether the first communication address is allowed to be used.

It is understandable that if the address allocation device fails for some reason, when the address allocation device allocates the first communication address to a certain OSU device and a certain OSU device is using the first communication address, the address allocation device allocates the first communication address to the first OSU device again. This will cause the router to establish a connection with the wrong OSU device according to the wrong correspondence when the router transmits the data packet later, resulting in data packet transmission errors, which will in turn increase the data packet transmission delay and affect the user experience. Therefore, in order to improve the accuracy of confirming that the first communication address has not been allocated, the first OSU device can send an address resolution request including the first communication address to other OSU devices to request other OSU devices to determine whether the first communication address has been used.

S304: If no second response information is received from any of the other OSU devices within the preset time period, it is determined that the first communication address is allowed to be used, and the first communication address is used as the communication address of the first OSU device.

The second response information is used to indicate that the first communication address has been used, and the preset time length may be preset by the administrator of the communication network, for example, the preset time length may be 10 seconds.

It should be understood that if the first communication address is not used by other OSU devices, then other OSU devices will not respond to the address resolution request after receiving the address resolution request including the first communication address. Therefore, when the second response information sent by any of the other OSU devices is not received within the preset time, it is determined that the first communication address is not used by other OSU devices, that is, it is determined that the first communication address is allowed to be used, and then the first communication address is used as the communication address of the first OSU device.

Optionally, if a second response message is received from any other OSU device within a preset time period, it is determined that the first communication address has been used by the OSU device, that is, it is determined that the first communication address is not allowed to be used. The first OSU device can send a fourth request message to the address allocation device, wherein the fourth request message is used to request the address allocation device to reallocate a communication address.

In some embodiments, when the first OSU device uses the first communication address as its own communication address, when the first OSU device is restarted, after the first OSU device is restarted, the first OSU device will automatically send a seventh request message to the address allocation device, and the seventh request message is used to request to continue using the first communication address as the communication address of the first OSU device.

Optionally, after receiving the seventh request information sent by the first OSU device, if the address allocation device determines that the first communication address has not been allocated, it sends permission information to the first OSU device. After receiving the permission information sent by the address allocation device, the first OSU device continues to use the first communication address as its own communication address.

Optionally, if the address allocation device determines that the first communication address has been allocated, the address allocation device sends a non-use information to the first OSU device. After the first OSU device receives the non-use information sent by the address allocation device, it can resend the above-mentioned discover broadcast message to the address allocation device, that is, perform the above-mentioned steps S301-S304 again, which will not be repeated here.

The following is an example of a network collaboration method provided by the present application, in conjunction with the communication system shown in FIG1 .

Assume that the router 121 as a source router needs to transmit a data packet to the router 123 (the router 123 is also the destination router), that is, the OSU device 111 is the first OSU device.

First, the router 121 sends a first request message to the OSU device 111. After receiving the first request message sent by the router 121, the OSU device 111 queries the correspondence between the communication address of the OSU device stored in itself and the network address of the router according to the network address of the router 123 included in the first request message. Assuming that the network address of the router 123 is Net-7, the correspondence between the communication address of the OSU device stored in the OSU device 111 and the network address of the router can be as shown in the above Table 2. After searching and comparing, no corresponding relationship related to Net-7 is found in the above Table 2, and it is determined that the OSU device 111 itself does not store the corresponding relationship related to the network address of the router 123, that is, the OSU device 111 does not store the corresponding relationship between the network address of the router 123 and the communication address of the OSU device. The OSU device 111 can send a second request message including the network address Net-7 of the router 123 to the OSU devices 112, 113, 114 and 115.

Assume that after receiving the second request information sent by the OSU device 111, the OSU device 112 searches for the corresponding relationship between the communication address of the OSU device stored in itself and the network address of the router in accordance with the network address Net-7 of the router 123 included in the second request information, and the communication address of the OSU device indicated by the corresponding relationship is OSU-UUID-G, that is, the communication address of the OSU device 113 is OSU-UUID-G. Then, the OSU device 112, as the third OSU device, sends a first response information including the communication address of the OSU device 113 to the OSU device 111.

After receiving the first response information including the communication address of the OSU device 113 sent by the OSU device 112, the OSU device 111 sends the communication address of the OSU device 113 to the router 121, and updates the corresponding relationship between the communication address of the OSU device 113 and the network address of the router 123.

Exemplarily, the correspondence between the communication address of the OSU device and the network address of the router after the OSU device 111 updates and stores the address may be as shown in Table 3 below.
