Abstract

Natural and manmade disasters often cause failures in network components. Such failures induce communication service interruptions as well as packet and economic losses. To provide adequate communication recovery in disasters, we propose here a local fast failure recovery scheme, called Unaffected Alternate Selection (UAS), for avoiding traffic congestion and to achieve high survivability in the event of single link and router failures. Our simulation results show that the proposed scheme can successfully disperse affected traffic flows and recover failed physical-layer network communication in disasters. Keywords: survivability, load balance, fast failure recovery.
