Development of distributed multimedia applications requires support
for coordination and temporal/causal synchronization of traffic over
related streams. Our current research involves investigation of
appropriate OS and communication abstractions to support such
applications. Towards this goal, we have designed and implemented
MCP, a suite of transport and session layer protocols, in the
framework of a standard BSD Unix networking platform. MCP contains
two new abstractions. First, MCP contains a token-based mechanism for
coordination of traffic over a multipoint connection. Second, MCP
includes an abstraction called a multi-flow conversation that enforces
both temporal and causal synchronization among related data streams.
This paper discusses Unix kernel implementation of MCP and describes
our experience in using MCP.
