Traffic engineering for MPLS
Wai Sum Lai · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2002
An analytical model is developed in this paper for evaluating the performance of bandwidth allocation algorithms, with or without preemption, when used for Diffserv-aware MPLS traffic engineering. It is shown that, a major difference between various algorithms is their capabilities to provide greater bandwidth sharing versus robust service protection/isolation.
