QoS. For this purpose it manages the bandwidth (the QoS services) within a network
domain and it is also responsible for the communication with Bandwidth Brokers of
adjacent domains. In this paper, we present a Bandwidth Broker implementation in the
widely used NS-2 simulation environment. We describe the Bandwidth Broker architecture
that was our model for the simulation implementation. Furthermore, we illustrate the
experiments that we conducted that examined the Bandwidth Broker functionality as well
as its performance. All the experiments demonstrated that with this implementation we can
achieve end-to-end QoS and that our implementation can be used in order to model the
behavior of a Bandwidth Broker in the widely popular NS-2 network simulator.1 aBouras, Christos1 aStamos, Kostas1 aPrimpas, Dimitris1 aStathis, N  uhttps://telematics.upatras.gr/telematics/publications/design-and-implementation-bandwidth-broker-simulation-environment
