Abstract

Admission control is a necessary component of a
real-time communication service.
The admission control method adopted so far in the
Tenet approach to real-time communication was based on a very simple, 
not very realistic node model.
The method described here can be applied to
a wide variety of node models with a wide spectrum of accuracies,
and is therefore much more general than the previous one.
The admission control tests and computations for the case
of the Earliest Due Date scheduling discipline
are shown as an example of application of the new method.
The main advantages and drawbacks of this method are discussed;
the predominance of the advantages is expected to be confirmed
by experience with testbed implementations.
