摘要：The short-lived failures are reasonably common in IP networks, there are many ways with which local rerouting can be provided for high availability but most of them are for single link failure. Here, we are suggesting a Localized Ondemand Link State (LOLS) routing to safeguard the forwarding continuity even with multiple failures limiting the propagation of failure information to just a few hops. LOLS cannot guarantee loop-free forwarding during route convergence and this is the reason why we are working on integrating Fast Convergence Fast Reroute (FCFR) technique with LOLS to ensure loop free rerouting and convergence even with multiple failures. Fast Convergence with Fast Reroute (FCFR), which uses a fast reroute scheme such as Not-Via and desires just one additional bit in the packet header with much less per-packet overhead. Integrating LOLS with FCFR is going to hold the quality of LOLS of loop free forwarding and overcome drawback of LOLS by ensuring loop free convergence
