Problems solved by technology

[0002] At present, with the rapid development of communication technology, the number of routing tables in the backbone network of the Internet (INTERNET) is increasing rapidly. The problem brought about by this is that it is necessary to upgrade or modify the router equipment that processes the routing table so that it has Corresponding processing power, which leads to the increase of the cost of the router and the decrease of the route convergence speed

Embodiment 1

[0075] see Figure 4 , in the method provided in Embodiment 1, the routing information carrying its own address information is released, and the border router receiving the information, if the edge network it is connected to contains the address prefix published in the routing information covered by more detailed address prefix, then according to the address information, register the mapping relationship between the detailed address prefix information and the border router address on the core router, so as to complete the mapping relationship to the corresponding border router on the core router registration; after performing the above configuration of the core router, the method specifically includes:

[0076] Step 401: the router addresses and forwards the data packet according to its own routing table;

[0077] Step 402: When the router forwards the data packet to the core router according to the address information of the core router itself, the core router searches for t...

Embodiment 2

[0093] see Figure 5 , in the method provided in this embodiment, the core router in the Internet backbone network publishes the aggregated prefix routing information carrying its own address information, and the border router receiving the information, if the edge network it is connected to contains the routing information The more detailed address prefixes covered by the address prefix published in , then according to the address information, register the mapping relationship between the detailed address prefix information and the border router address in the core router, so as to complete the To the registration of the corresponding border router mapping relationship; after performing the configuration of the core router as above, the method specifically includes:

[0094] Step 501: For the data packet that needs to be forwarded, the border router searches for the best matching route with the forwarding destination address of the data packet, if the best matching route is t...

Abstract

The embodiment of the invention discloses a routing information diffusion method, a method for realizing data packet routing, a system and a device thereof. The routing information diffusion method comprises the steps that: equipment for diffusing routing information obtains own address information; the equipment for diffusing routing information adds the own address information into the routing information to be diffused; the equipment for diffusing routing information diffuses aggregation route prefix information carrying the own address information. The proposal provided by the embodiment of the invention can greatly reduce the number of routing tables, avoid the increasing problem of router cost and effectively overcome the problem that routing convergence speed is low. In addition, by adopting the routing information diffusion method provided by the embodiment of the invention, a router in a backbone network can dynamically obtain the address information of a core router that diffuses an aggregation prefix, thereby being capable of conveniently realizing the registration, update and inquiry of more detailed information mapping from the routing prefix to a border router.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for publishing routing information, a method, a system and a device for realizing data packet routing. Background technique [0002] At present, with the rapid development of communication technology, the number of routing tables in the backbone network of the Internet (INTERNET) is increasing rapidly. The problem brought about by this is that it is necessary to upgrade or modify the router equipment that processes the routing table so that it has Corresponding processing capabilities lead to the increase of router costs and the reduction of route convergence speed. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present invention is to provide a method for distributing routing information, a method, a system and a device for implementing data packet routing, so as to reduce the number of routing tables that route...
