Fast self-healing for node failures in ATM networks
R.-F. Chang, Yih‐Fuh Wang · 2002
Network restoration becomes an essential function for a high speed network since service disruption due to network failures can cause a huge tangible and intangible loss for customers and service providers. We propose a VP-based distributed self-healing to rapidly restore the disrupted VPs from node failures. The developed scheme can provide a priority restoration based on the survivability requirement of services. By simulation, we verify the features of the proposed scheme and the simulation results show that high priority VPs can be resorted in a high restoration rate for node failures and single link failure.
