Multicast distributed routing algorithm for providing network QoS

Multicast routing is widely used by various media applications (teleconference, distance learning...). The combination of multicast routing and quality of service (QoS) characteristics helps handling the technical requirements and brings better services to end-users. This paper proposes an extension of distributed routing algorithm (DRA) for supporting multicast routing. The proposed algorithm is called multicast distributed routing algorithm (MDRA). Our simulations results show that MDRA provides better network performance by reducing network overhead while keeping the call admission ratio in an acceptable range.
