| Popis: | 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. In this paper we present a simulation study that evaluates several fast rerouting scenarios depending on the number of leaves of a MP2MP bypass TE-tunnel and on the number of primary TE-tunnels that can be encapsulated into one MP2MP bypass TE-tunnel. In particular, the scalability/bandwidth efficiency tradeoff between these schemes is analyzed and valuable comparisons with the existing approaches are presented. |
