Much of the researches in network resource management have been devoted to providing bandwidth guarantees and preventing network congestion. However, most of them rely on load balancing to avoid network bottlenecks, tailoring on the other hand longer and costly paths. They ignore that longer paths can badly affect on both quality of routing, and usage(More)
This paper presents a new bandwidth management framework supporting Differentiated Services aware Traffic Engineering (DSTE) in the Multi-Protocol Label Switching (MPLS). Our bandwidth management framework contains route computation, bandwidth allocation and preemption for Label Switched Paths (LSPs). We put forward two algorithms. The first one, named(More)
This paper presents a new bandwidth preemption algorithm supporting differentiated services aware traffic engineering (DS-TE) in the multi-protocol label switching (MPLS). The paper presents the following contributions. Firstly, we look at the problem of organizing the mapping of label switching paths (LSPs) in an optimal way such that we can compromise(More)
