Credibility based QoS (Quality of Service) route selection method

Abstract

The invention provides a credibility based QoS (Quality of Service) route selection method, comprising the following parts of node joinin and quit, message transmission, credibility calculation and route table design. In the node joinin and quit part, a distance vector protocol is adopted, and each node communicates with neighbor nodes to obtain information of other nodes; in the message forwarding process, a splitting and recombination mode is adopted to forward the messages of different parts through different routes; and in a credibility calculation model, each node is only responsible for forwarding the messages to the neighbor nodes and only carries out credibility collection and evaluation on the neighbor nodes of the node. In the invention, QoS indexes, such as business type identification, business bandwidth requirement and the like, are added in the credibility requirement so as to ensure that a router can make a route selection decision with higher safety and certain service guarantee according to the credibility of next hop, path length, business bandwidth and the like in a complex network environment.

Description

technical field [0001] The present invention relates to a research on safe and reliable requirements in network transmission and a routing system routing method for providing appropriate QoS services, in particular to a trust-based QoS routing routing method, which belongs to the technical field of routing methods in network communication . Background technique [0002] The rapid development of network technology and applications has made the Internet more and more popular, and the sharing of Internet content is also getting higher and higher. It also brings some unsafe factors, such as unauthorized users of the system obtain information that should be hidden from them; security mechanisms are bypassed; users pretend to be other authorized users, and the responsibility is attributed to the wrong person; Listen on the communication line to obtain confidential data; the data communicated between nodes is destroyed, etc., introducing the concept of trust between routing nodes ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to propose a QoS route selection method based on trust degree in view of the network insecurity factors existing in the above-mentioned background technology, to provide relatively safe and reliable packet forwarding and provision in complex network environments. Certain QoS services enable routers to select routes according to the business type to which the packets belong
