N2 - Failure recovery using IP fast reroute (IPFRR) has gained much attention recently. The basic idea is to find backup paths and configure the routing tables in advance. After a failure is detected, the pre-determined backup paths are used immediately to forward the affected packets. Since the calculation and configuration are performed in advance, the recovery can be completed very quickly. IPFFR is considered as a promising approach to enhance the survivability of IP networks. While single failure recovery has been extensively researched, using IPFRR for double-link failure recovery remains as a great challenge. We propose a solution for this issue called Efficient SCan for Alternate Paths for double-link failure recovery (ESCAP-DL). ESCAP-DL guarantees 100% coverage from both single and double-link failures and has the advantages of low complexity and resource requirement. The scheme resumes packet forwarding immediately after failures are detected and does not require failure advertising throughout the network.
