Implement MPLS Traffic Engineering over Network System

One of the required characteristic of any network is the capacity to keep services running after node or network failure. This ability is known as network flexibility and an important for service providers. The flexible of networks recover from failure by fixing them automatically by transferable traffic from failed node of the network to another portion of the network. The traffic transferable process should be fastest to guarantee that the obstruction of service due to a network or link failure is either unnoticeable or as small as possible and kept the service running. in the proposed system MPLS TE for use Fast Reroute mechanism to providing backup and redundancy tunnel that can be programmed in to the router. This way to recalculate the paths happens before the failure actually occurs. Fast Rerouting protects paths from link and node failures and networks by locally repairing the protected paths and re-routing them through backup tunnels at same the point of failure and allowing the data to flow continuously. In case of a network failure or node.
