Abstract

The need for real-time multimedia applications like streaming video, VOIP has increased over commercial organizations, reliability and availability has become important issues. Such Networks are prone to failures because of different reasons (e.g. unreliable equipment, software bugs or cable cut). Such faults and failures may affect the operation of LSPs and cause packet loss. VoIP packets are sensitive to packet losses and transmission delay to assure correct communication. This paper proposes Efficient Fault Recovery Two Phase Routing for VoIP Applications and its performance based on forward error correction technique. With this approach packet losses against link failures can be recovered by using Vandermonde Matrix Level FEC mechanism. VoIP packets can be routed in two phases in contrast to the traditional single path routing approach to perform load balancing. Simulation results are reported to show the efficiency of the proposed technique when compared with single path routing for effective VoIP flows.
