Abstract

In this paper we use the well known network
simulator ns-2 in order to study the performance
characteristics of various alternatives for the admission
control module of a Bandwidth Broker. In particular, we
present the modifications that have to be made at the ns-2
architecture in order to simulate these architectures, the
metrics such as acceptance rate, fairness towards requests
and computation overhead and how they are affected
when comparing a simple admission control module and
more sophisticated ones. Furthermore, we examine the
benefits that can arise under various circumstances
through usage of enhancements such as the ability to
handle the resubmission of previously rejected requests.
