Resubmissions and Partly Defined Requests in an Adaptive Admission Control Algorithm for Bandwidth Brokers

The purpose of this paper is to examine the issues
related to the efficiency and adaptability of the
admission control module of a Bandwidth Broker. The
proposed architecture is able to handle situations such
as the resubmission of previously rejected requests and
offer a fair treatment for requests in an environment
where a subset of these requests do not specify their
ending time. We describe the proposed mechanisms for
such cases which aim at solving the additional
problems of fairly prioritizing resubmitted requests
and efficiently handle requests which do not specify
ending times. We also provide experimental
evaluations of the proposed algorithms and the
conclusions they lead us to.
