摘要：
The Label Switch Path routing algorithm in Multiprotocol Label Switching (MPLS) has become an important topic in Traffic Engineering. This paper presents a new routing scheme with precomputation, called the Least Maximum Flow Categories Routing Algorithm. In the MPLS network, different ingress-egress pairs have different maximum flow values on different links. Each link has a vector consisting of the maximum flow values flowing through it. This paper considers these vectors as weights of links and presents a method for calculating them. Simulation results show that the algorithm has the same precision as the other algorithms but has less computational complexity. Copyright (C) 2011 John Wiley & Sons, Ltd.
