MPLS-Traffic Engineering (MPLS-TE) provides many recovery mechanisms such as rerouting and protection. Existing one-to-one backup and path-based backup schemes are not resource efficient. We propose Common Protection Path (CPP), a novel protection scheme which selects a common protection path for traffic demands having the same ingress and egress routers. CPP also factors in path failure probability and restoration priority levels of the traffic demands. Simulation results show that the protection bandwidth reservation required for one-to-one backup scheme is 1.85 to 4.43 times that of CPP scheme and for dedicated path-based scheme it is 1.10 to 1.78 times that of CPP scheme.

“…The optimal solution of the ILP problem leads to a network engineering with working and recovery paths for every accepted traffic demand, which maximizes the overall residual capacity, allowing the maximum possible number of traffic demands to be satisfied. An efficient resource allocation is addressed by applying the shared protection [9] [10]. On each link the maximum bandwidth needed for all possible working conditions (i.e.…”

Next-Generation Networks (NGNs) employ the Internet Protocol (IP) over a wide variety of packet-switching technologies, which often lack in fault resilience enabling features. An overlay MPLS infrastructure with its fast-reroute mechanisms can be deployed to overcome such an issue. Addressing NGNs robust to single link and node failures, an offline method to effectively calculate working and recovery paths for highly demanding services, is proposed and analyzed. The strength of our work is the ability to address two recovery techniques in a very simple manner, by formulating an Integer Linear Programming (ILP) problem, optimizing either the overall switching delay experienced by the user in case of failure or the bandwidth allocation thanks to a shared protection, while limiting the recovery time to some tens of ms as in SONET/SDH networks.
