Abstract
An important means to guarantee an acceptable quality of service in
networks with real-time communication requirements is the
reservation of resources at connection setup time. However, such
reserved resources, e.g. transmission bandwidth, may be unused as a
consequence of the variations in the actual resource demands.
Therefore, a more efficient resource utilization is possible if
communicating stations or end-users dynamically hand over some of
the free resources temporarily to the other communication partners,
e.g. of a ``broadcast network''.
This paper concentrates on two fundamental problems of such a
demand-based sharing of resources: on the one hand, estimation of
the current resource requirement on the basis of load measurements
is investigated and, on the other hand, we elaborate efficient
algorithms for resource sharing respecting real-time requirements.
The algorithms proposed for load estimation and for resource sharing
are evaluated analytically with respect to their efficiency for
worst-case, average-case and realistic load scenarios. Our approach
suggested for resource and traffic management allows one to achieve
significantly better utilization of network resources.
