The conventional optical transport network OTN is used as a physical bearer network, can support transparent transport of client signals, multiplexing exchange and configuration of high bandwidth, and has a strong overhead support capability. The technology is mainly positioned in the application of a backbone network and a metropolitan area network, is used for bearing the service with the speed of more than 1Gbits/s, and has the following problems after the OTN sinks to the metropolitan area/access network: insufficient pipe flexibility (minimum pipe ODU0), a small number of connections, insufficient flexibility in bandwidth scaling, etc. The industry provides the concept of an optical service network, defines the service-oriented OSU container standard, adopts more flexible pipeline bandwidth definition, can more efficiently bear small-particle signal service, realizes the service-oriented optical bearing technology, and further promotes the development of an all-optical service network.

Therefore, it is necessary to automatically establish an optical transport network (e.g., OSU) connection according to the traffic information of the IP layer network, so as to implement automatic connection management of traffic awareness, and further implement efficient cooperative work of the IP layer network and the optical layer network.

Fig. 1 is a schematic structural diagram of a communication system according to an exemplary embodiment of the present application. 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 integers.

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

In some embodiments, an address assignment device is also included in the communication network, and the address assignment device may be a separate physical device, such as a server or a computer. The server may be a single server, or may be a server cluster including a plurality of servers. In some embodiments, the server cluster may also be a distributed cluster, and the specific type of the address allocation device is not limited in this embodiment.

In some embodiments, the address assignment device is configured to assign communication addresses to M OSU devices in the communication network.

It should be understood that fig. 1 is an exemplary architecture diagram and that the communication system shown in fig. 1 includes an unlimited number of devices. The communication system shown in fig. 1 may include other devices besides the device shown in fig. 1, which is not limited to this.

As shown in fig. 2, a flowchart of a network coordination method is provided for an embodiment of the present application, where the method is executed by a first OSU device, and the first OSU device may be any one of 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, and the method includes the following steps:

s101, acquiring a communication address of a first OSU device, and acquiring a network address of a first router connected with the first OSU device from the first router.

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

Optionally, the correspondence between the communication address of the OSU device itself and the network address of the router connected to the OSU device itself may be established by the OSU device receiving information input by operation and maintenance personnel of the communication network, and establishing the correspondence between the communication address of the OSU device itself and the network address of the router connected to the OSU device itself according to the information input by the operation and maintenance personnel. Or the OSU device automatically establishes a correspondence between the communication address of the OSU device and the network address of the router connected to the OSU device after acquiring the communication address of the OSU device based on an artificial intelligence autonomous learning algorithm.

It should be noted that, if the correspondence between the communication address of the OSU device and the network address of the router connected to the OSU device is established by receiving the information input by the operation and maintenance staff, the operation and maintenance staff are required to manually allocate the communication address of each OSU device, which is likely to cause a large workload of the operation and maintenance staff, and in consideration of the complexity of the operation and maintenance, in the embodiment of the present application, an autonomous learning method based on artificial intelligence may be adopted, so that the OSU device automatically establishes 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 automatically establishes a correspondence between its own communication address and a network address of a router connected to the first OSU device by using an artificial intelligence-based autonomous learning method, the first OSU device may obtain its own communication address from the address assignment device, and as to how the first OSU device obtains its own communication address from the address assignment device, reference may be made to the following description about step S301 to step S304, which is not described herein again.

In some embodiments, the first OSU device may send a sixth request message to the first router connected to the first OSU device, where the sixth request message is used to request the network address of the first router, and the first OSU device receives a third response message sent by the first router, where the third response message includes 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.

S102, establishing a corresponding relation between the communication address of the first OSU device and the network address of the first router.

For example, 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 relationship between the communication address of the first OSU device and the network address of the first router can be established as shown in table 1 below.

TABLE 1

Serial number	Communication address of OSU device	Network address of router
			1	OSU-UUID-A	Net-1

S103, synchronizing the corresponding relation 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 may be implemented as: and sending fifth request information to other OSU equipment, wherein the fifth request information comprises the corresponding relation between the communication address of the first OSU equipment and the network address of the first router, and the fifth request information is used for requesting the other OSU equipment to store the corresponding relation between the communication address of the first OSU equipment and the network address of the first router.

In some embodiments, if the 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, 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 fifth response information sent by each of the other OSU devices, where the fifth response information is used to indicate that the correspondence between the communication address of the first OSU device and the network address of the first router is agreed to and stored.

And after the first OSU equipment receives the fifth response information sent by each of the other OSU equipment, responding to the fifth response information, and storing the corresponding relation between the communication address of the first OSU equipment and the network address of the first router. In this way, the M OSU devices in the communication network all store the correspondence between the communication address of the first OSU device and the network address of the first router synchronously.

Based on the embodiment shown in fig. 2, as can be seen from the above description about the first OSU device, the first OSU device may be any one of M OSU devices, that is, when each OSU device joins the communication network, the above steps S101 to S103 need to be executed, that is, when each OSU device establishes a correspondence between its own communication address and a network address of a router connected to itself, the correspondence needs to be synchronized to other OSU devices in the communication network. Therefore, the OSU devices in the communication network all store the corresponding relation between the communication address of each OSU device and the network address of the router connected with the OSU device, so that when the router connected with one OSU device needs to transmit data to the target router, the communication address of the OSU device connected with the target router can be quickly found according to the corresponding relation between the OSU device and the router of the communication network stored by the OSU device connected with the router, the OSU device can automatically establish connection with the OSU device and determine the shortest path of the transmitted data, the data can be quickly transmitted, the transmission rate of the data can be increased, and the efficient cooperative work of an IP layer network and an optical layer network is realized.

The above-described embodiments have focused 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 establishment of the correspondence between the communication address of the OSU device and the network address of the router, the above-described embodiments also include 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 fig. 3, the network coordination method further includes the following steps:

s201, receiving 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 first request information sent by the first router, where the first request information is used to request a communication address of a second OSU device connected to the second router. Wherein 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 message may further include an IP address of the first router, a port number of the second router, a third layer protocol type, a sampling ratio of the port, a receive timestamp of the first request message, a Transmission Control Protocol (TCP) sequence number, and the like.

S202, judging whether the corresponding relation related to the network address of the second router is stored or not according to the network address of the second router.

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 a communication address of the second OSU device, and as can be known from step S101, the second OSU device is an OSU device connected to the second router.

Illustratively, as shown in table 2 below, the correspondence between the communication address of the OSU device and the network address of the router is stored for the first OSU device.

TABLE 2

Serial number	Communication address of OSU device	Network address of 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 traverse its own database with the network address of the second router as an index, and determine whether it stores a corresponding relationship related to the network address of the second router.

If not, the following steps S203 to S205 are executed.

If yes, the following step S206 is performed.

And S203, if the corresponding relation related to the network address of the second router is not stored in the OSU, sending second request information comprising the network address of the second router to other OSU equipment.

If the corresponding relation related to the network address of the second router is not found in the database of the first OSU device according to the network address of the second router serving as the index, it is determined that the corresponding relation related to the network address of the second router is not stored in the database of the first OSU device, and the first OSU device may send second request information including the network address of the second router to other OSU devices, wherein the second request information is used for requesting to acquire the communication address of the second OSU device connected with the second router.

For example, assuming that the network address of the second router is Net-7, the network-7 is used as an index to traverse the table 2, and the correspondence relationship related to Net-7 is not found, that is, it is determined that the first OSU device does not store the correspondence relationship related to the network address of the second router.

It can be understood that, if the database of the first OSU device does not store the correspondence relationship related to the network address of the second router, and it may be that the time when the first OSU device joins the communication network is later, so that the correspondence relationship between the communication address of the second OSU device and the network address of the second router is not synchronized to the database of the first OSU device, the first OSU device may send the second request message to the other OSU devices, so as to obtain the communication address of the second OSU device connected to the second router.

And S204, receiving first response information sent by the third OSU equipment.

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 may determine whether the other OSU devices store 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. And if the corresponding relation related to the network address of the second router is stored in the router, sending first response information to the first OSU equipment.

S205, sending the corresponding relation related to the network address of the second router to the first router.

It should be understood that the correspondence relationship related to the network address of the second router is sent to the first router, that is, the communication address of the second OSU device connected to the second router is sent to the first router, so that the first router determines the shortest transmission path between the first router and the second OSU device according to the communication address of the second OSU device, automatically establishes a connection with the second OSU device, and transmits a data packet to the second OSU device.

Further, while sending the corresponding relationship related to the network address of the second router to the first router, the first OSU device may store the corresponding relationship related to the network address of the second router, that is, supplement and update the corresponding relationship between the communication address of the OSU device and the network address of the router in the communication network stored by the first OSU device in real time, so that when the first router transmits data to the second router again, the connection with the second OSU device may be quickly established according to the updated corresponding relationship, thereby increasing the rate of establishing connection between the first router and the second OSU device, and increasing the transmission efficiency of data packets.

S206, if the corresponding relation related to the network address of the second router is stored in the router, the corresponding relation related to the network address of the second router is sent to the first router.

If the first OSU device stores the corresponding relationship related to the network address of the second router, it represents that the first OSU device stores the communication address of the second OSU device connected to the second router, and the first OSU device may send the communication address of the second OSU device to the first router.

Illustratively, if the network address of the second router is Net-5, it is determined according to Net-5 through the above table 2 that the correspondence relationship related to the network address of the second router is stored in itself, and the communication address of the second OSU device having the correspondence relationship with the network address Net-5 of the second router is OSU-UUID-C, and the first OSU device sends the communication address of the second OSU device OSU-UUID-C to the second router.

In some embodiments, as shown in fig. 4, the above step S101 for acquiring the communication address of the first OSU device may be embodied as the following steps S301 to S304.

S301, receiving a first communication address which is sent by an address allocation device in a broadcast mode and allocated to a first OSU device.

In some embodiments, when an OSU device joins the communication network, a discovery discover broadcast message may be sent to the communication network to discover the address assignment device in the communication network. After receiving the discover broadcast message, the address allocation device may send, in a broadcast manner, the first communication address allocated for the first OSU device to the first OSU device according to the use condition of its own address resource pool. Further, the first OSU device receives the first communication address sent by the address allocation device.

S302, third request information is sent 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, where the third request information is used to request the address allocation device to determine whether the first communication address is allocated.

It can be understood that, since the address allocating device sends the first communication address allocated to the first OSU device in a broadcast manner, other OSU devices in the communication network may also receive the first communication address, and if one OSU device is also an OSU device newly joining the communication network, the OSU device may also use the first communication address as a communication address allocated to it by the address allocating device, so that after the first OSU device receives the first communication address sent by the address allocating device, the first OSU device may send third request information including the first communication address to the address allocating device to request the address allocating device to determine whether the first communication address has been allocated to the other OSU devices.

And S303, if receiving the confirmation non-allocation information sent by the address allocation equipment, sending an address resolution request comprising the first communication address to other OSU equipment.

In some embodiments, if the address allocating device determines that the first communication address is allocated after receiving the third request message sent by the first OSU device, the address allocating device still sends the reallocated communication address to the first OSU device in a broadcast manner.

In some embodiments, if the address allocating device determines that the first communication address is not allocated, the first OSU device receives an acknowledgement non-allocation message sent by the address allocating device, and further, the first OSU device determines that the first communication address is not allocated according to the acknowledgement non-allocation message.

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

It can be understood that, if the address allocating device fails due to some reason, when the address allocating device allocates the first communication address to one of the OSU devices and one of the OSU devices is using the first communication address, the address allocating device allocates the first communication address to the first OSU device, which may cause the router to establish a connection with the wrong OSU device according to the wrong correspondence when the router transmits the data packet, resulting in a data packet transmission error, which may further cause an increase in data packet transmission delay, and affect user experience. Therefore, 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 the other OSU devices to request the other OSU devices to determine whether the first communication address is used.

S304, if the second response information sent by any one of the other OSU devices is not received within the preset time length, determining that the first communication address is allowed to be used, and taking the first communication address as the communication address of the first OSU device.

The second response message is used to indicate that the first communication address is used, and the preset time period may be preset by an administrator of the communication network, for example, the preset time period may be 10 seconds.

It should be appreciated that if the first communication address is not used by other OSU devices, the other OSU devices do 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 one of the other OSU devices is not received within the preset time length, it is determined that the first communication address is not used by the other OSU devices, that is, 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.

Optionally, if second response information sent by any one of the other OSU devices is received within the preset time duration, it is determined that the first communication address is already used by the OSU device, that is, it is determined that the first communication address is not allowed to be used, and the first OSU device may send fourth request information to the address assignment device, where the fourth request information is used to request the address assignment device to reassign a communication address.

In some embodiments, after the first OSU device uses the first communication address as its own communication address, in case that the first OSU device is restarted, after the first OSU device is restarted, the first OSU device may automatically send seventh request information to the address allocation device, where the seventh request information is used to request to continue using the first communication address as the communication address of the first OSU device.

Optionally, after the address allocating device receives the seventh request information sent by the first OSU device, if it is determined that the first communication address is not allocated, the address allocating device sends the usage permission information to the first OSU device. And after receiving the use permission information sent by the address allocation device, the first OSU device continues to use the first communication address as the communication address of the first OSU device.

Optionally, if the address allocating device determines that the first communication address is allocated, the address allocating device sends the non-use permission information to the first OSU device. After receiving the information that is not allowed to be used and sent by the address allocating device, the first OSU device may send the discover broadcast packet to the address allocating device again, that is, execute step S301 to step S304 again, which is not described in detail herein.

A network coordination method provided in the present application is described below with reference to the communication system shown in fig. 1.

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

First, the router 121 transmits first request information 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 and the network address of the router, which is stored in the OSU device, 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 itself and the network address of the router may be as shown in table 2, and through the search and comparison, the correspondence related to Net-7 is not found in table 2, and it is determined that the correspondence related to the network address of the router 123 is not stored in the OSU device 111 itself, that is, the correspondence between the network address of the router 123 and the communication address of the OSU device is not stored in the OSU device 111. The OSU device 111 can send second request information including the network address Net-7 of the router 123 to the OSU device 112, the OSU device 113, the OSU device 114, and the OSU device 115.

Assuming that after the OSU device 112 receives the second request information sent by the OSU device 111, according to the network address Net-7 of the router 123 included in the second request information, the correspondence related to the network address Net-7 of the router 123 is found in the correspondence between the communication address of the OSU device stored in the OSU device and the network address of the router, and the communication address of the OSU device indicated by the correspondence is OSU-UUID-G, that is, the communication address of the OSU device 113 is OSU-UUID-G, the OSU device 112 serves as a third OSU device to send 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 and stores the correspondence between the communication address of the OSU device 113 and the network address of the router 123.

For example, the correspondence between the communication address of the OSU device and the network address of the router after the OSU device 111 updates the storage may be as shown in table 3 below.

Serial number	Communication address of OSU device	Network address of router
			1	OSU-UUID-A	Net-1
2	OSU-UUID-C	Net-5
			3	OSU-UUID-D	Net-9
