%0 Conference Paper %B 7th International Symposium on Communications Interworking - INTERWORKING 2004, Ottawa, Canada %D 2004 %T Design and implementation of a Bandwidth Broker in a simulation environment %A Christos Bouras %A Kostas Stamos %A Dimitris Primpas %A N Stathis %X A Bandwidth Broker is an entity that has been proposed in order to provide end-to-end 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. %B 7th International Symposium on Communications Interworking - INTERWORKING 2004, Ottawa, Canada %8 29 November - 1 December %G eng
