Paths Optimal Ordering Algorithm Based on MPLS Traffic Engineering

With the development of network technology, QoS routing algorithm based on MPLS traffic engineering becomes the focus of the information industry. An improved algorithm is proposed based on the known algorithms. For optional paths of each ingress-egress pair, the algorithm uses a learning mechanism, combines offline and online routing, and chooses the LSP in terms of the average expectation load and the residual bandwidth by calculating the maximum flow of network, simultaneously considers other QoS parameters. The simulation results indicate that it is an efficient and quick routing algorithm.
