The traditional optical transport network OTN is used as a physical bearing network, can support transparent transmission of client signals, multiplexing exchange and configuration of high bandwidth, and has strong overhead supporting capability. The technology is mainly positioned in backbone network and metropolitan area network application and is used for bearing the service with the speed greater than 1Gbits/s, and after the OTN sinks to the metropolitan area/access network, the following problems exist: insufficient pipe elasticity (minimum pipe ODU 0), few connections, inflexible bandwidth adjustment, and the like. The industry provides the concept of an optical service network, defines the OSU container standard facing the service, adopts more flexible pipeline bandwidth definition, can more efficiently bear small-particle signal service, realizes the optical bearing technology facing the service, and further promotes the development of the all-optical service network.

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

In some embodiments, the communication network further includes an address allocation device, which may be a separate physical device, such as a server or computer. The server may be a single server, or may be a server cluster formed by 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 the embodiments of the present application.

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

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

As shown in fig. 2, a flowchart of a network collaboration method is provided for an embodiment of the present application, where the method is performed 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 from the first router connected with the first OSU device.

When an OSU device joins the communication network, it needs to learn the communication address of itself and the network address of the router connected to itself, so as to establish a correspondence between the communication address of itself and the network address of the router connected to itself.

Optionally, the correspondence between the communication address of the OSU device and the network address of the router connected to the OSU device may be that the OSU device receives information input by an operation and maintenance person of the communication network, and establishes the correspondence between the communication address of the OSU device and the network address of the router connected to the OSU device according to the information input by the operation and maintenance person. Or the OSU device can automatically establish the corresponding relation between the communication address of the OSU device and the network address of the router connected with 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 personnel, the operation and maintenance personnel is required to manually allocate the communication address of each OSU device, which is easy to cause large workload of the operation and maintenance personnel, and considering the complexity of operation and maintenance, the embodiment of the application may use an autonomous learning method based on artificial intelligence, 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 adopts the autonomous learning method based on artificial intelligence, the first OSU device may acquire the own communication address from the address allocation device when automatically establishing the correspondence between the own communication address and the network address of the router connected to the first OSU device, and for how the first OSU device acquires the own communication address from the address allocation device, reference may be made to the following description about steps S301 to S304, which will not be repeated herein.

In some embodiments, the first OSU device may send a sixth request message to a first router connected to the first OSU device, where the sixth request message is used to request a network address of the first router, and further, 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 (virtual local area network, VLAN) information, etc.

S102, establishing a corresponding relation between a communication address of the first OSU device and a 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 between the communication address of the first OSU device and the network address of the first router may be set as shown in table 1 below.

TABLE 1

Sequence 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.

Alternatively, step S103 may be specifically implemented as: and sending fifth request information to other OSU equipment, wherein the fifth request information comprises a 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 device agrees 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 device stores 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 and stored.

After the first OSU device receives the fifth response information sent by each of the other OSU devices, the first OSU device responds to the fifth response information to store a corresponding relation between the communication address of the first OSU device and the network address of the first router. 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, as can be seen from the foregoing description about the first OSU device, the first OSU device may be any one OSU device of the M OSU devices, that is, when each OSU device joins the communication network, the foregoing steps S101-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. In this way, the OSU device in the communication network stores the correspondence 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 destination router, the correspondence between the OSU device and the router of the communication network stored by the OSU device connected with the OSU device can be quickly found, the communication address of the OSU device connected with the destination router is automatically established, the connection with the OSU device is automatically established, the shortest path for transmitting data is determined, the data is quickly transmitted, the data transmission rate can be improved, and the efficient collaborative work of the IP layer network and the optical layer network is realized.

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 further includes the process of using the correspondence between the communication address of the OSU device and the network address of the router after the correspondence between the communication address of the OSU device and the network address of the router is established. In some embodiments, as shown in fig. 3, the network collaboration method further includes the steps of:

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), the 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 information comprises a network address of the second router, e.g. an IP address of the second router.

Optionally, the first request information 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 ports, a reception timestamp of the first request information, a transmission control protocol (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 according to the network address of the second router.

The correspondence relationship related to the network address of the second router may be a correspondence relationship between the network address of the second router and the communication address of the second OSU device, and as known from the step S101, the second OSU device is an OSU device connected to the second router.

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

TABLE 2

Sequence 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 its own corresponding relationship related to the network address of the second router is stored.

If not, the following steps S203-S205 are performed.

If yes, the following step S206 is executed.

And S203, if the corresponding relation of the network address of the second router is not stored, 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 router according to the network address of the second router as an 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 router, and the first OSU device may send second request information including the network address of the second router to other OSU devices, where the second request information is used to request to obtain the communication address of the second OSU device connected to the second router.

For example, assuming that the network address of the second router is Net-7, the table 2 is traversed with Net-7 as an index, and no corresponding relation related to Net-7 is queried, that is, it is determined that the first OSU device does not store the corresponding relation related to the network address of the second router.

It can be understood that if the own database does not store the correspondence related to the network address of the second router, that is, the time when the first OSU device joins the communication network is possibly later, so that the correspondence 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 information to other OSU devices, so as to obtain the communication address of the second OSU device connected to the second router.

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

The first response information includes a correspondence related to a network address of the second router, and the third OSU device is any one OSU device 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 the corresponding relationship related to the network address of the second router is stored 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 second router, the first response information is sent 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 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, according to the communication address of the second OSU device, the shortest transmission path between the first router and the second OSU device, and automatically establishes connection with the second OSU device, and further transmits the data packet to the second OSU device, so that the time consumed by the connection between the first router and the second OSU device can be reduced, that is, the transmission efficiency of the data packet can be improved, and efficient cooperation between the IP layer network and the optical layer network is realized.

Further, when the corresponding relation related to the network address of the second router is sent to the first router, the first OSU device can store the corresponding relation related to the network address of the second router, namely, the corresponding relation between the communication address of the OSU device and the network address of the router in the communication network stored by the first OSU itself is supplemented and updated in real time, so that when the first router transmits data to the second router again, the connection with the second OSU device can be quickly established according to the updated corresponding relation, the connection establishment rate of the first router and the second OSU device is improved, and the transmission efficiency of the data packet is improved.

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 relation related to the network address of the second router, the communication address of the second OSU device connected with the second router is stored on behalf of the first OSU device, and the first OSU device can send the communication address of the second OSU device to the first router.

For example, if the network address of the second router is Net-5, the table 2 is traversed according to Net-5, a corresponding relationship related to the network address of the second router is determined, and a communication address of the second OSU device having a corresponding relationship with the network address Net-5 of the second router is OSU-UUID-C, and 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 step S101 described above with respect to acquiring the communication address of the first OSU device may be implemented as the following steps S301-S304.

S301, receiving a first communication address distributed to a first OSU device by an address distribution device in a broadcasting mode.

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 address assignment devices in the communication network. After receiving the discover broadcast message, the address allocation device may send, according to the use condition of its own address resource pool, a first communication address allocated to the first OSU device in a broadcast manner to the first OSU device. Further, the first OSU device receives the first communication address transmitted 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 has been allocated.

It will be appreciated that, since the address allocation 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 the communication address allocated by the address allocation device, so 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 to request the address allocation device to determine whether the first communication address has been allocated to the other OSU device.

And S303, if the confirmation unassigned information sent by the address assignment equipment is received, sending an address resolution request comprising the first communication address to other OSU equipment.

In some embodiments, if the address allocation device determines that the first communication address has been allocated after receiving the third request information sent by the first OSU device, the address allocation device still sends the reassigned communication address to the first OSU device in a broadcast format.

In some embodiments, if the address allocation device determines that the first communication address is not allocated, the first OSU device receives acknowledgement unallocated information sent by the address allocation device, and further, the first OSU device determines that the first communication address is not allocated according to the acknowledgement unallocated information.

Optionally, after the first OSU device determines that the first communication address is not allocated, in order to improve 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 device, where the address resolution request is used to request the other OSU device to determine whether the first communication address is allowed to be used.

It can be understood that if the address allocation device fails due to a certain reason, when the address allocation device allocates the first communication address to a certain OSU device and the certain OSU device uses the first communication address, the address allocation device allocates the first communication address to the first OSU device again, which can cause that the router establishes 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, further resulting in an increase of the data packet transmission delay and affecting the user experience. The first OSU device may send an address resolution request including the first communication address to the other OSU device to request the other OSU device to determine whether the first communication address has been used in order to improve accuracy of confirming that the first communication address has not been allocated.

And S304, if the second response information sent by any one of the other OSU devices is not received within the preset time, 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 information is used to indicate that the first communication address has been used, and the preset duration may be preset by a manager of the communication network, for example, the preset duration 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 will not respond to the address resolution request after receiving the address resolution request including the first communication address. And when the second response information sent by any one of the other OSU devices is not received within the preset time, determining that the first communication address is not used by the other OSU devices, namely determining that the first communication address is allowed to be used, and further taking the first communication address as the communication address of the first OSU device.

Optionally, if the second response information sent by any one of the other OSU devices is received within the preset 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 allocation device, where the fourth request information is used to request the address allocation device to reallocate a communication address.

In some embodiments, after the first OSU device uses the first communication address as its own communication address, in a case where the first OSU device is restarted, the first OSU device automatically sends seventh request information to the address allocation device after the first OSU device is restarted, where the seventh request information is used to request that the first communication address be continuously used as the communication address of the first OSU device.

Optionally, after receiving the seventh request information sent by the first OSU device, the address allocation device sends permission information to the first OSU device if it is determined that the first communication address is not allocated. After the first OSU device receives the usage permission information sent by the address allocation device, the first communication address is continued to be used as the communication address of the first OSU device.

Optionally, if the address allocation device determines that the first communication address is allocated, the address allocation device sends the disallowed use information to the first OSU device. After receiving the disallowed use information sent by the address allocation device, the first OSU device may resend the discover broadcast message to the address allocation device, that is, execute the step S301 to the step S304 again, which is not described in detail herein.

A network collaboration method provided in the present application is illustrated below in conjunction with the communication system shown in fig. 1.

Assume that router 121 acts as a source router and needs to transmit a packet to router 123 (router 123, i.e., the destination router), i.e., OSU device 111 acts as a first OSU device.

First the router 121 sends the first request information to the OSU device 111. After receiving the first request information sent by the router 121, the OSU device 111 queries, according to the network address of the router 123 included in the first request information, the correspondence between the communication address of the OSU device stored in itself and the network address of the router. 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 may be as shown in the above table 2, and by virtue of the lookup comparison, the correspondence related to Net-7 is not found in the above table 2, and it is determined that the OSU device 111 does not store the correspondence related to the network address of the router 123, that is, the OSU device 111 does not store the correspondence between the network address of the router 123 and the communication address of the OSU device. The OSU device 111 may send the 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, a corresponding relationship related to the network address Net-7 of the router 123 is found in a corresponding relationship between a communication address of the OSU device stored in the OSU device and the network address of the router, and a communication address of the OSU device indicated by the corresponding relationship is OSU-UUID-G, that is, a communication address of the OSU device 113 is OSU-UUID-G, the OSU device 112 sends, as a third OSU device, first response information including a 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 correspondence between the communication address of the OSU device 113 and the network address of the router 123.

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