Abstract

In this paper we present and compare four different
models of implementing a Bandwidth Broker in a DiffServ
network. We describe the relevant implementation aspects in the
well-known ns-2 simulator and present a number of experiments
that were conducted in order to verify our implementation,
analyze the performance characteristics of the various
alternatives and evaluate the usefulness of the ns-2 simulation
environment for similar purposes. We present our experiments
that aim at investigating a number of issues related to the
operation of Bandwidth Broker modules, and in particular how
the acceptance rate, the network overhead and the response time
for each Bandwidth Broker model are affected by the network
topology, the available buffers for incoming requests and the
advance time from the moment a request is submitted to the
moment the reservation should take place.
