Enhancing Fault Tolerance and Rerouting Strategies in Mpls Networks

Multi Protocol Label Switching (MPLS) has been used to provide traffic engineering and high speed networking. MPLS is an evolving network technology. MPLS is a framework which is introduced by IETF. It is a differentiated and scalable framework. MPLS delivers end-to-end IP services with the use of simple configuration and management. Fault tolerance is an important Quality Of Service factor. Fault tolerance needs to be considered to maintain network survivability. Fault tolerance is very important in every network system because it provides the facility to operate the network if any one or more parts of the system are damaged. The network devices are enabled by MPLS to specify path based on quality of service and bandwidth. The main use of MPLS technology is to speed up the network flow with the use of labels.
