Survivable Online Routing for MPLS Traffic Engineering
Traffic engineering capabilities defined in MPLS enables QoS online routing of LSPs. In this paper we address issues of network survivability in online routing. We define a new link weight LFL (Lost Flow in Link) that can be applied for dynamic routing of LSPs in survivable MPLS network. We propose to use the LFL metric as a “scaling factor” for existing dynamic routing algorithms that make use of additive metrics. Results of simulations show that the new metric can substantially improve the network survivability defined as the lost flow function after KSP local rerouting. However, the application of LFL metric slightly increases the number of rejected calls.
