【Abstract】 Several explicit routing algorithms for Internet traffic engineering were analyzed and compared, in order to put forward the architecture for distributed and on line implements of MPLS Traffic Engineering. To improve the scalability of MPLS Traffic Engineering through optimizations of the performance of minimal interference routing algorithm, new link state advertisement mechanism was introduced, together with the combination of centralized and distributed computing methods. It was shown that not only the computation efficiency of the minimal interference routing algorithm, but also the scalability of the MPLS traffic engineering system were obviously enhanced through the treatments.更多还原
