Abstract:

Various aspects should be considered when evaluating a recovery technique (protection/restoration): recovery time, bandwidth protection, required backup capacity, scope of recovery, additive latency, state overhead, ... This session will describe how MPLS Traffic Engineering FRR can be used not only for fast recovery but also for bandwidth protection, as other technologies like Sonet/SDH, ... but with a more effective bandwidth usage. An efficient model called ?Facility based computation model? will be presented for computing bypass tunnels paths in the context of the MPLS TE Fast Reroute, while allowing bandwidth sharing between backup tunnel protecting independent resources. Both a centralized and a distributed path computation scenarios will be described with a particular focus on the distributed case. The required routing and signalling extensions will also be covered.

Jean-Philippe Vasseur has a French engineer degree and a Master of Science from the SIT (New Jersey USA). He worked for several Service Providers in large multi-protocol environment prior to joining CISCO. After two years within the EMEA Technical consulting group, focusing on IP/MPLS routing, VPN, Traffic Engineering designs for the Service Providers, he joined the CISCO Engineering team and works on IP/MPLS architecture specifications with a particular focus on MPLS Traffic Engineering and protection/restoration. He co-authors several IETF drafts.
