ANALYSIS OF ENHANCED HOP BY HOP FEEDBACK BASED HIERARCHICAL MPLS PROTOCOL

摘要

MPLS network is based on label based packet forwarding within the network but as the network grows the MPLS network causes delay than the normal network as routing table to label table lookup is required at the ingress and egress routers. To overcome this problem hierarchical MPLS network was proposed which is better in larger network. In this paper we proposes a feedback based hierarchical network which gives feedback on hop by hop basis within the network which also reduces the delay time of the network in case of packet loss and provide more security than the existing network.
