In IP networks routing failure is a common problem which leads to low packet delivery ratio. The routing protocols are not always fast enough to react and recover from failures. Fast reroute solutions have been proposed and developed in recent years which ensure route availability and reduce the packet loss. The existing solutions address either the intra-domain failures or the inter-domain failures due to their computation mechanisms and methodologies. In this paper, the authors propose a combined unified solution for inter as well as intra domain routing failures using the concept of e-cycle and double protection e-cycle along with backup path.
