Abstract

In this paper we introduce a novel scheme for multicast communications and describe the implementation choices of a new suite of TCP-friendly transport protocols optimised for reliable and unreliable multicast connections over satellite networks. The suite is composed of two protocol optimised for different applications: the RMT (Reliable Multicast Transport) guarantees a reliable file delivery; the UMT (Unreliable Multicast Transport) is suitable for multimedia streaming. Both RMT and UMT adopt a TCP-Peach like congestion control scheme to optimise the performance in satellite networks. The new protocols have been implemented on top of UDP in a Unix environment and their performance has been evaluated in an emulated satellite network environment.
