Dasgupta, S: Improving Resource Management in MPLS-TE Networ

Multi-Protocol Label Switched (MPLS) based Traffic Engineering (TE) is a common and effective resource management option deployed by several service providers to tackle the explosive growth in traffic volume.This book discusses new MPLS based TE mechanisms capable of dealing with traffic changes while illustrating the analysis and performance metrics that are involved in ing one. Specifically, new techniques for dynamic bandwidth allocation and routing are proposed and developed through simulations under failure and non-failure scenarios. Issues related to inter-domain deployment are also studied. With the emergence of numerous successful open source efforts that provide routing and forwarding services coupled with decreasing hardware costs, it is easier than before to build testbeds with specific goals. principles of an Application Programming Interface (API) for a platform that will allow TE experimentation is discussed. Sample experiments on a prototype are illustrated for motivating the development of open architectures that will allow performance analysis of custom TE techniques on commercial equipment.
