摘要：Various technologies about multi-path calculation for extensibility and failure restoration have been suggested as an increasing demand for QoS in MPLS networks. However, the MPLS networks have problems in extensibility for network traffic, failure restoration that waste usage of resources and much delay. Thus, we propose to H-MPLS networks recover failure in networks fast and support efficient methods for network management using a LSP multiple routing algorithm. We also organize expanded networks with a hierarchical MPLS network and apply various failure restoration methodologies to it. We demonstrate, analyze it by the NS simulator and propose improving ideas.
