Abstract/Summary:
In this work, we have implemented a routing framework, called Virtual Route, which uses Link State routing protocol to provide network survivability for critical services in a dynamic routing environment. If a network link or a node becomes untrusted, the link state protocol provides different information to different services. A new routing algorithm is developed taking into account different link state information for Survival Critical and Normal services. The Virtual Route concept is implemented as an extension to the simulator, MuSDyR. Based on extensive simulation, we show that Survival Critical service can receive prioritized Quality of Service over Normal traffic, and a network maintaining at least the number of Trusted Links equal to the edges in a minimum spanning tree would at least be beneficial to Survival Critical traffics.
