Abstract: Based on the analysis of algorithms have been proposed, this paper proposes the Paths Optimal Ordering Algorithm(POOA) for routing issue of Multi-Protocol Label Switch(MPLS) Traffic Engineering(TE). The algorithm uses a learning machine. It can automatically learn from information proposed by a random environment, calculate the best routing priorities, and determine the best path forward by this. The simulation results indicate that routing reject ratio of the routing algorithm is smaller than that of other algorithms, its calculation speed is faster than that of other algorithms, and it can guarantee Quality of Service(QoS), so it is an efficient and quick routing algorithm.
