Simulation of advanced bandwidth broker implementation in PLC networks

The bandwidth broker is a management instance inside a PLC system, which has the complete overview about the network topology, the actual reserved bandwidth on each link inside its domain and should ideally have also a real-time view of the available bandwidth on each link. In this paper, we present a Bandwidth Broker implementation in the simulation environment. 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.
