Embodiment Construction

[0028] The following will take a typical network as an example to illustrate a method of introducing a new transient routing table based on the original routing table, so as to avoid the problem of invalid data flow transmission and network load increase that may be caused by the default route.

[0029] see figure 1 As shown in , it is a flow chart of data flow forwarding processing when the network condition is normal.

[0030] For example, router A, router B, router C, and router D simulate a most common hierarchical routing access network. The code of the interface connecting router A to the backbone network is 5; the code of the interface connecting router A and router B is 4; the code of the interface connecting router B and router A is 3; the code of the interface connecting router B and router C is 1; the code of the interface connecting router B and router D 2.

[0031] Such as figure 1 As shown, there is no temporary failure of the device, and the normal situation ...

Abstract

The utility model discloses a processing method that reduces ineffective transmission of network traffic, comprising: step 1, transient routing is generated; step 2, the transient routing is the table entry of a transient routing table, and the transient routing table is arranged in the default routing of the routing table; step 3, when receiving a data stream, the router searches the routing table according to the destination and transmits the data stream; when the destination of the data stream does not match with the specific routing in the routing table and the data stream is forwarded byusing the default routing table entry, the transient routing table listed under the default routing is searched; if the destination of the data stream matches with the table entry in the transient routing table, the data stream is directly discarded. The utility model enables correct discard of data streams with ineffective destinations, thus reduces ineffective transmission of network traffic caused by transmitting data streams according to the default routing, reduces unnecessary wasting of network devices, and enables the network more stable.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a processing method for reducing invalid transmission of network traffic. Background technique [0002] The existing Internet technology is becoming more mature and the scale is getting bigger and bigger. The use of routers and switches is becoming more and more common. Residential communities and companies can build their own networks and connect to the Internet. In this way, the routing needs to be more and more detailed. As a result, the amount of routing becomes larger and larger. In actual network applications, based on the purpose of reducing the routing table of local routers or switches, the use of aggregated routes and default routes is very common. However, while aggregated routes and default routes bring the advantages of simplifying and clarifying network management, they also cause many problems, such as loopback of data flow and increased network load. The result...
