Path Computation Algorithm Using Delay & Bandwidth Constraint
Shalley Tyagi, Rakesh Kumar Singh · 2014
MPLS is a fast forwarding mechanism which provides support for traffic engineering. In the MPLS network constraint based routing computes routes, it not only considers the topology of the network but also another parameters such as bandwidth, delay etc. It may find a longer but lightly loaded path which is better than heavily loaded shortest path. This paper deals with modification of Wang-Crow croft algorithm based on best fit approach in the computation of label switch path resulting increases the quality of service. Both algorithms have been implemented in NS-2 and compared on the basis of throughput.
