Abstract
We present a novel architecture for providing a reliable
multicast transport service over existing protocol
stacks. These protocol stacks ordinarily support reliable
unicast transport layer connections over a network layer
which is capable of providing an unreliable multicasting
service. We propose the addition of a new Single Connection
Emulation (SCE) sublayer between the unicast transport
layer and the multicast network layer. This added
layer mimics the single destination network layer interface
to the transport layer and interfaces with the multicast
network layer to provide the necessary multicast function
ality. The new architecture also enables interactions
between applications and the SCE, thus allowing the
applications to control the semantics of the reliable
multicast connection. We discuss the design issues that need
to be considered when such a sublayer is to be introduced.
We also discuss an implementation of this new approach
using the TCP/IP protocol stack.and present some preliminary
experimental results.
