Evaluation of Scalability and Bandwidth Efficiency of Multipoint to Multipoint Hierarchy for Fast Recovery in MPLS Networks

Multi-Point To Multi-Point -Traffic Engineering (MP2MP-TE) leads to an important scalability in Multi Protocol Label Switching-Traffic Engineering (MPLS-TE) networks. This paper emphasizes on the support of Fast-ReRoute (FRR) in MPLS-TE networks by using MP2MP bypass TE-tunnels. Hence, one MP2MP bypass TE-tunnel can be used to protect several primary TE-tunnels. During failure, the primary TE-tunnel is encapsulated into the MP2MP bypass TE-tunnel which calls for defining a new type of MPLS hierarchy, i.e. the multipoint to multipoint hierarchy.
