Route selection method for solving problem of wired network congestion

Abstract

The invention discloses a route selection method for solving a problem of wired network congestion. According to the route selection method, traditional active routing networking is still used in a wide area network, on-demand routing of a preceding jump of router before a congestion point is driven through congestion monitoring, an idle link is sought in a certain range, and a congestion chain is kept off to perform business transmission. The route selection method has the advantages that the congestion chain is kept off to reasonably guide business transmission, overload of the congestion chain is relieved until the load returns to normal, and the problem of wired network congestion is solved to some extent; in specific realization, the router only needs to be simply upgraded, traditional routing protocols are not modified, intercommunication between a basic routing networking function and a traditional routing protocol is not affected, routing inquiry messages are produced within a limited scope only when congestion is generated, or network expenditure is low.

Description

technical field [0001] The invention relates to congestion management technology and routing technology in the field of communication, in particular to on-demand routing technology. Background technique [0002] With the development of network technology and applications, high-speed real-time data transmission has become an inevitable demand in the information age, and the primary problem to be solved is congestion. Congestion means that during a certain period of time, the demand for a certain resource in the network exceeds the available part that the resource can provide, which will lead to the deterioration of the characteristics of the network. Congestion management is a dynamic and complex problem, because congestion is often caused by various reasons. Traditional ideas generally use queue management technologies such as FIFO, PQ, CQ, WFQ, and CBWFQ. In the early stage, it can indeed solve some problems caused by insufficient forwarding capabilities of equipment. Howe...

Problems solved by technology

[0007] The beneficial technical effects of the present invention are: it can avoid congested links, reasonably guide service forwarding, alleviate the overload of congested links until it returns to normal, and solve the problem of wired network congestion to a certain extent; Simply upgrade the router without modifying the traditional routing protocol, without affecting the basic routing networking function of the network and the intercommunication of the traditional routing protocol, and only generate routing query messages within a limited range when congestion occurs, and the network overhead is small
