摘要：
Due to the requirement of high reliability and availability of electric communication network (ECN), an optimized routing algorithm with load and risk joint balance (LRJB) was proposed to decrease the blocking probability and service risk value of the network. Firstly, the bandwidth occupation of nodes and links in ECN was analyzed based on the characteristics of traffic flow, and a load balancing model was established. Secondly, the risk balance strategy was designed by analyzing the link availability and service risk with service importance factor under different protection modes according to the characteristics of ECN. In order to reduce the blocking probability and risk of the network, the balance factor was introduced to balance the load traffic and risk value jointly. An ECN from a city in Jiangsu was selected as a test network to verify the effectiveness of LRJB. Simulation results demonstrate that compared with existing routing algorithm with load balance and algorithm with minimum fault risk loss, the proposed algorithm can balance the link load flow and the risk value simultaneously, and yields the decrease of congestion rate and service risk of the network. © 2019 Chin.
