Credible inter-domain route selection method

Abstract

The invention discloses a credible inter-domain route selection method. According to the credible inter-domain route selection method, false path detection is carried out by a partial detection node, the credibility of nodes in a network is calculated according to detection results, and the credibility is released to an inter-domain chord ring after the calculation is completed; and when other nodes which are not subjected to false path detection mechanism deployment are subjected to route selection, the credibility of nodes on candidate paths is obtained from the chord ring, the credibility of the paths is calculated, and finally, true and credible paths are selected for release. The method comprises the steps of: (1) selecting credible information sources when the false path detection is carried out by the partial detection node; and (2) selecting partial nodes from the Internet so as to construct the chord ring. According to the credible inter-domain route selection method, a credibility mechanism is introduced into inter-domain route decision, inter-domain route information is subjected to credibility evaluation, and the true and credible paths are selected for release.

Description

technical field [0001] The invention belongs to the field of computer networks, and relates to a route control method, in particular to a trusted inter-domain route selection method. Background technique [0002] The Internet is divided into multiple autonomous system , an autonomous system is an entity, generally referring to a road Depend on device collection. each autonomous system can make your own routing Strategy. autonomous system Internal router through the domain Routing Protocol Exchange routing information with each other, general intra-domain routing protocols are divided into Distance Vector Protocol and link state protocols; autonomous system border routers exchange routing information through inter-domain routing protocols. Currently, the de facto standard for inter-domain routing protocols on the Internet is the BGP-4 protocol. The lack of credibility of the current inter-domain routing mechanism is mainly reflected in the fact that it cannot i...
