Bearer network flow optimizing method, router, optimizing server and bearer network system

Abstract

The invention provides a bearer network flow optimizing method, a router, an optimizing server and a bearer network system. The bearer network flow optimizing method comprises the steps of judging whether business information to be transmitted is transit business or not, if so, sending a routing request to the optimizing server, wherein the routing request carries starting router address information and target router address information to enable the optimizing server to obtain a transmission path according to the starting router address information and the target router address information; receiving routing information sent by the optimizing server and carried with the transmission path and sending the business information according to the transmission path, wherein transmission nodes corresponding to all of address information in the transmission path are common core layer nodes. By means of the bearer network flow optimizing method, transmission load of a super core layer can be effectively decreased, transmission efficiency of the business information can be improved, and enlargement of transmission capability of an existing bearer network is facilitated.

Description

technical field [0001] The invention relates to computer network technology, in particular to a bearer network traffic optimization method, router, optimization server and bearer network system. Background technique [0002] The backbone network of the existing network operator's basic bearer network includes a super core layer and a general core layer. Among them, the super core layer not only tandems and forwards the internal IP network traffic of the autonomous system domain (AS) domain, but also has the egress function from the local network to other AS domains. Generally, the core layer is mainly used to tandem and forward service traffic within the AS domain. Such as figure 1 In the example of the bearer network in the same AS domain shown, eight fully interconnected router nodes in the middle constitute the super core layer. These eight router nodes are: SA1, SA2, SB1, SB2, SC1, SC2, SD1 and SD2. The other router nodes remaining in the figure constitute the general...

AI Technical Summary

Problems solved by technology

Since all business information such as transit business traffic and cross-AS domain business traffic needs to occupy the transmission resources of the super core layer, the burden of transmitting business information on the super core layer is increased, and the service information transmission efficiency of the bearer network is seriously affected.
