Abstract

Many multicast applications require reliable delivery of data packets to multiple receivers. Scalability is one of the key challenges in the design of reliable multicast. The major obstacles of the scalability are feedback implosion and retransmissions. Furthermore, a real network changes with time. A reliable multicast protocol must adapt to such dynamic change of multicast sessions. Thus, it is necessary to design an efficient and adaptive loss recovery scheme for reliable multicast. In this thesis, we present an efficient and adaptive loss recovery scheme, which is based on the performance evaluation of reliable multicast. The multicast performance depends on the loss recovery mechanism, the underlying tree topology, the loss characteristics, and the locations of repair servers. We present an efficient performance evaluation of these basic performance parameters, which is useful for adequate determination of the locations of repair servers
