Research on selection method of service security link in power communication network

Abstract

In order to solve the problems of bandwidth limitation, delay limitation and link risk in power communication network, this paper studies the method of service security link selection in power communication network, and proposes a service security link selection model for power communication network. Considering the short distance of transmission link, network bandwidth, delay and link risk, a service security link selection model of power communication network is established. Quantitative analysis of the importance of service security, combined with the improved dejerstra algorithm and PSO algorithm to solve the optimal link of power communication network business security, to achieve the global risk balance of power communication network business and ensure the safe and stable operation of the whole communication network.
