Christoph Hanle Vrije Universiteit Amsterdam De Boelelaan 1081A, 1081 HV Amsterdam, The Reliable multicast protocols on top of the MBone are presently subject to intensive research. One major jield of interest is the transmission of files to large sets of receivers, In this paper, we introduce Multicast File Transfer Protocol (MFTP), which is gaining increased popularity in the commercial sector and present an enhanced version of the latter, called Multicast File Transfer Protocol with Erasure Correction (MFTP\EC), which uses a low-cost XOR-based erasure correction technique to increase the eficiency of retransmission. We build a simplified model of the MBone and use the network simulator ns2 to simulate network trafjic ha great detail. We validate the characteristics of the simulated network with previous work on MBone measurements and present the performance of MFTP and the gain that can be achieved using our erasure correction scheme.
