【摘要】 本文对MPLS中的流量工程进行讨论。在MPLS网络中,我们通常采用流量工程资源预留协议(RSVP-TE)和约束路由标记分发协议(CR-LDP)来建立LSP,这两种信令协议通过基于约束的选路方式(简称为约束路由)或基于源的选路方式(简称为源路由)来提供QoS。本文对流量工程中的核心技术——约束路由进行了深入探讨,提出了一种在MPLS网络中建立LSP的最佳路由方案,该方案可以提供保证型的QoS。更多还原

【Abstract】 In this paper we will discuss traffic engineering in MPLS. RSVP- TE and CR- LDP which are used for LSP setup usually use constraint - based or source -based routing in the MPLS domain to provide QoS. Wealso further discuss the core technology in TE--constraint - based routing, and propose an optimal routingscheme for LSP setup to provide guaranteed QoS in MPLS networks.更多还原
