新一代电力ICT网络中基于DiR保护环的生存性路由算法
Survival routing algorithm based on DiR protection ring in novel power ICT network
摘要
Abstract
The protections of services in power communication network occupy so many network resources. Through studying the influence of reliability requirements of smart grid services on the network resource utilization efficiency, the survival routing algorithm based on differentiated reliability protection ring is proposed. On the condition of a single link failure in the network and under the constraint of link cost and link failure probability, through finding a minimum cost path protection ring, the connection request is established on the light path which can satisfy the failure probability requirement and minimize the path cost. Simulation results show that the algorithm can improve the network resources utilization efficiency with meeting the reliability requirements of smart grid and reducing the occupying ratio of network resources, and the performance is better than that of traditional methods.关键词
