Review paper of enhance the efficiency of the network by enhancing the error recovery by using the backup path in MPLS network

Note The MPLS QoS ingress and egress policies for MPLS traffic classify traffic on the EXP value in the received topmost label when you enter the match mpls experimental command..

As in the traditional IP network, IP routing protocols are used to forward the packets but, in MPLS network, label switched routers (LSRs) use label switching as the

The mechanism for MPLS routing is for the Provider Edge router to insert a “Label” in the data packet before the Network (in this case IP) header.. The Provider Routers in the

In contrast to the connectionless model used in IP networks, MPLS establishes a Label Switched Path (LSP) into which packets are encapsulated by an edge MPLS router after assigning

(3) When the label request message reaches the destination router or the egress router of the MPLS network, if the router has available labels, and judges the label
