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...
In today's service provider networks MPLS Traffic Engineering (MPLS TE) is one of the fastest growing implementation. MPLS adoption in service provider networks has increased manifold due to its inherent TE capabilities. A purpose of traffic engineering in a network is to setting up paths between the edge nodes of the network to meet traffic demands while optimizing network performance. It is known...

IMS is the evolution of the UMTS toward an all-IP network supporting IP-based multimedia services, like VoIP, conferencing, push-to-talk or mobile gaming. As new services require high restrictions in network parameters, the support for QoS in necessary. The aim of this paper is to present the policy based architecture in IP multimedia subsystem of UMTS, its components and their interactions.
