Abstract

It is a critical issue for interdomain service routing across MPLS domains to map egress service path. In spite of being a de facto interdomain routing standard, BGP can not effectively fulfil the interdomain traffic engineering. To solve the problem, we set up an overlay model, and formulate the problem as a Markov Decision Problem. According to the model, we get related network resource state through service nodes measurement on a common measurement platform. Using service state, we design related cost function. To simplify the problem, we decompose the Markov Decision Problem, and design a heuristic proportional mapping algorithm.
