We present a novel architecture for providing a reliablemulticast transport service over existing protocolstacks. These protocol stacks ordinarily support reliableunicast transport layer connections over a network layerwhich is capable of providing an unreliable multicastingservice. We propose the addition of a new Single ConnectionEmulation SCE sublayer between the unicast transportlayer and the multicast network layer. This addedlayer mimics the single destination network layer interfaceto the transport layer and interfaces with the multicastnetwork layer to provide the necessary multicast functionality. The new architecture also enables interactionsbetween applications and the SCE, thus allowing theapplications to control the semantics of the reliablemulticast connection. We discuss the design issues that needto be considered when such a sublayer is to be introduced.We also discuss an implementation of this new approachusing the TCP-IP protocol stack.and present some preliminaryexperimental results.
