Traffic engineering and multiprotocol label switching as mean to improve network efficiency

Multiprotocol label switching (MPLS) is an emerging technology that provides scalability, flexibility and use the available bandwidth in the network in an efficient way. Signaling protocols like constraint based routing; the label distribution protocol and the resource reservation protocol can be used to enable good traffic engineering. Interior gateway protocols work in conjunction with signaling protocols and their strong binding result in better performance of the network. In this thesis, we have analyzed the performance of the signaling protocols used in the MPLS paradigm for traffic engineering. These signaling protocols are meant to provide support for traffic engineering using MPLS and in this way help to increase the performance of the network. Some issues related to increase the efficiency of the signaling protocols are scrutinized. How the resource reservation protocol has been extended to support traffic engineering in multi protocol label switching paradigm is also discussed. Moreover, application of multiprotocol label switching to traffic engineering is implemented in a proposed network
