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.
