DISTRIBUTED ADVANCE RESERVATION OF REAL-TIME CONNECTIONS

The ability to reserve real-time connections in advance is essential i n all distributed multiparty applications (i.e., applications involvin g multiple human beings) using a network that controls admissions to p rovide good quality of service. This paper discusses the requirements of the clients of an advance reservation service, and a distributed de sign for such a service. The design is described within the context of the Tenet Real-Time Protocol Suite 2, a suite being developed for mul tiparty communication, which will offer advance reservation capabiliti es to its clients, based on the principles and the mechanisms proposed in the paper. Simulation results providing useful data about the perf ormance and some of the properties of these mechanisms are also presen ted. We conclude that the one described here is a viable approach to c onstructing an advance reservation service within the context of the T enet Suites as well as that of other solutions to the multiparty real- time communication problem.
