Abstract

The reactive recovery methods have a long recovery time to deal with the network failures, which cannot meet the requirements of real-time applications for network delay and packet loss rate. Therefore, router vendors generally use DC rules to handle failures in the network. However, the complexity of existing algorithms to implement DC rules is generally high, and increases with the increase of network node degree. Therefore, this paper studied how to reduce the complexity of implementing DC rules, and proposed an efficient DC implementation method. This paper first extended the DC rule, then implemented the extended DC rule in the process of constructing the shortest path tree, and finally analyzed the time complexity of the algorithm theoretically. The experimental results show that EDCS not only has less computational overhead, but also can compute all the backup next hops that conform to DC rule.
