In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

Embodiment one

FIG. 1 is a flow chart of a flow control method in Embodiment 1 of the present invention. The traffic control method provided in this embodiment is applicable to the situation where traffic is controlled by equipment in various scenarios. The method can be specifically executed by a traffic control device, which can be implemented by software and/or hardware. The device Can be integrated in the device, the device can be a network device, such as a switch, router, firewall, NFV (Network Function Virtualization, network function virtualization) device and other network devices, referring to Figure 1, the method of the embodiment of the present invention specifically includes:

S110. Acquire configuration information of routing mutual guidance, where at least one routing table process as a learning object and a target routing table process as a party to be learned are recorded in the configuration information.

Wherein, the routing mutual guidance configuration information is information pre-configured by technicians, which records at least one routing table process as a learning object, and a target routing table process as a party to be learned, which is used to indicate the routing table process in the routing table process. The learning object and the party to be learned, and the learning object of the direction to be learned to learn. The routing table process is a program running in a network device. At least one routing table process can be created and run in a network device. Each routing table process manages at least one internal routing protocol, and each routing table process corresponds to form a routing table process. routing table. The routing table is an electronic form (file) stored in the network device, which stores a path pointing to a specific network address, contains topology information of the network periphery, and is used to implement a routing protocol.

S120. Obtain routing information of each routing table process that is a learning object.

Wherein, the routing information is the information included in the routing table process that reflects the parameters of the routing process, such as gateway information, interface information, network mask information, network protocol information, and the like. For at least one routing table process as the learning object, other routing table processes as the party to be learned need to learn at least one routing table process as the learning object, therefore, obtain the routing information of each routing table process, so as to serve as the party to be learned The routing table process learns according to the routing information. The routing information is acquired through a pre-opened interface in the routing table process.

It should be noted that, in the embodiment of the present invention, in order to improve the comprehensiveness of obtaining routing information, the routing information of each routing table process as a learning object is obtained, so as to avoid obtaining the routing information of some routing table processes as a learning object. information, resulting in incomplete route information acquisition and reduced acquisition efficiency. However, not all the routing information of the routing table process as the learning object must be used for learning, and only part of the routing information can be learned, or all the routing information can be learned, which can be determined by demand , therefore, no limitation is set in this embodiment of the present invention.

S130. Distribute the routing information of each routing table process as a learning object to a target routing table process, so that the target routing table process forwards the traffic based on the learned routing information.

In a large enterprise, multiple routing protocols may be used in the same network. In order to realize the collaborative work of multiple routing protocols, network devices can use route redistribution, but redistribution can only solve different routes based on one routing table. The information transfer between protocols cannot realize the information transfer between different routing tables. However, if the information in the routing table is directly copied without associating with the corresponding protocol, the details will be lost and the optimal path cannot be selected.

Therefore, in the embodiment of the present invention, first obtain at least one routing table process as the learning object recorded in the routing configuration information, and the target routing table process as the party to be learned, and the network device uses the routing table process of each routing table process as the learning object The routing information is distributed to the target routing table process, so that the learning of the routing information is performed between the routing table processes. Moreover, since the routing information carries the protocol attributes of the original routing protocol, compared with the method of directly copying the routing table, this method of introducing routing information based on the control plane realizes information transmission and learning at the control plane, making The transmitted and learned information includes detailed attribute information of the protocol, and the target routing table forwards the traffic based on the learned routing information, so as to realize adaptive and elastic traffic control in the process of dynamic routing.

Wherein, the target routing table process is used as the party to be learned, and among the routing information obtained from each routing table process as the learning object, if it is the same protocol routing information as the protocol in the target routing table process, then learning refers to obtaining The routing information; if it is protocol routing information different from the protocol in the target routing table process, then learning means that after obtaining the routing information, it is translated into initial routing information that can be understood by the protocol in the target routing table process.

Optionally, route filtering information is also recorded in the configuration information; correspondingly, the routing information of each routing table process as the learning object is distributed to the target routing table process, so that the target routing table process is based on the learned route Before the information forwards the traffic, the method further includes: filtering the obtained routing information according to the routing filtering information; correspondingly, distributing the routing information of each routing table process as the learning object to the target The routing table process includes: distributing the filtered routing information among the routing information of the routing table processes serving as learning objects to the target routing table process.

Wherein, the route filtering information is information used to indicate to filter the routing information. When learning the routing information, it is often not necessary to learn all the routing information, but only part of the routing information needs to be learned to achieve flexible traffic control. Therefore, the routing filtering information is recorded in the configuration information in advance , after obtaining the routing information of each routing table process as the learning object, first filter each routing information according to the routing filtering information, filter out the routing information that needs to be learned, and then distribute the filtered routing information to the target routing Table process, the routing information is learned by the target routing table process, for example, only the 10.0.0.0 network segment route publishing output is required, then the information is filtered according to the route, and the value corresponding to the 10.0.0.0 network segment is filtered out from the obtained routing information output value Routing information, the target routing process only learns the routing information corresponding to the 10.0.0.0 network segment, so as to avoid learning redundant routing information to reduce processing efficiency, and avoid the routing table generated by the target routing table process learning a large amount of routing information from occupying too much space.

Optionally, routing attribute modification information is also recorded in the configuration information; correspondingly, the routing information of each routing table process as the learning object is distributed to the target routing table process, so that the target routing table process is based on the learned Before the routing information forwards the traffic, the method further includes: judging according to the routing attribute modification information whether there is information that needs attribute modification in the obtained routing information, and when it is judged necessary, modifying the corresponding routing information The information attribute is modified; correspondingly, the routing information of each routing table process as the learning object is distributed to the target routing table process, including: the modified routing information of each routing table process as the learning object Routing information is distributed to the target routing table process.

Wherein, the routing attribute modification information is used to indicate modification of the routing information attribute. In some scenarios, a route for a network segment may already exist in the target routing table corresponding to the target routing process. The attribute of the above-mentioned routing information, and the routing of the network segment in the routing information is set to have different priorities from the existing routing of the network segment. Therefore, in the embodiment of the present invention, the routing attribute modification information is pre-recorded in the configuration information. After the routing information of each routing table process as the learning object is obtained, the routing information is firstly modified according to the routing attribute modification information. modify, and then distribute the modified routing information to the target routing process, and the target routing process learns the modified routing information. Exemplarily, when the route of the 10.0.0.0 network segment already exists in the target routing table corresponding to the target routing process, if the routing information of the routing process obtained as the learning object also includes the route of the 10.0.0.0 network segment, At this time, according to the routing attribute modification information, the routing attribute of the 10.0.0.0 network segment included in the routing information is changed to a suboptimal route, and then it exists as a suboptimal route after being learned by the target routing process.

The technical solution of the embodiment of the present invention is to obtain routing mutual guidance configuration information, wherein at least one routing table process as a learning object is recorded in the configuration information, and a target routing table process as a party to be learned; Routing information of each routing table process; distributing the routing information of each routing table process as a learning object to a target routing table process, so that the target routing table process forwards traffic based on the learned routing information.
