Abstract: In this work, it presents a review on Rerouting model in MPLS Network for reducing traffic. It is based on fault tolerant model concept in MPLS network. This describes the process of routing scheme and link resource distribution. QoS is the mechanism of the network to provide different service level to a different traffic type as business need.The main objective of this work is to improve QoS in network by reducing delay. It provides a distribution of traffic between source and destination so that delays between the paths are minimum between each other. It works on reliability by limited usage of bandwidth. The projected mechanism will be implemented with MATLAB.

Keywords: MPLS Network, Congestion Management, Re-Route Model, Quality of Service etc.
