摘要: 对支持流量工程的各种显式路由算法进行了比较,提出了在线分布实施MPLS(Multi-Protocol Label Switch)流量工程的优化体系结构.通过引入扩展LSA(Link State Advertisement)发布机制,采用分布和集中相结合的方式,使最小干涉路由算法的性能得到优化,同时提高了系统的可扩展性.

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.
