Traffic Engineering Using Multiple Multipoint-to-Point LSPs
Traffic engineering aims to optimize the utilization of existing network resources for load balance and failure recovery, and these are to be accomplished in a scalable fashion. This paper proposes a traffic engineering scheme using multiple multipoint-to-point (m-t-p) Label Switched Paths (LSPs) which can reduce the number of LSPs and required labels in links. The scheme consists of m-t-p LSP creation and flow assignment. Routes are first selected, and m-t-p LSPs are designed to include them. The m-t-p LSP design problem is formulated as a 0-1 integer programming problem. The flow assignment problem is formulated as a mixed integer programming problem in which maximum link load, i.e., maximum congestion, is minimized. Numerical comparisons with the conventional pointto-point LSP approach show that the m-t-p LSP approach can reduce the number of required LSPs and labels. Moreover, numerical comparisons with conventional Shortest Path Fast based flow assignment show that our flow assign...
