Abstract
Current QoS-based multicast routing protocols assume adequate fault free service from underlying network. However, this assumption is not realistic as network equipments may malfunction during operation. We consider fault recovery one of the critical features for practical deployment of QoS-based multicast routing protocols. This paper proposes and reports an implementation of a fault recovery mechanism for QROUTE - a leaf-initiated QoS-guaranteed multicast routing protocol. We then compare the fault recovery mechanism with a well-known existing multicast fault recovery mechanism via simulation. Simulation results indicate the proposed fault recovery mechanism performs better in terms of the fault recovery time, the fault recovery overhead and the fault recovery rate.
