Fast Local Rerouting using Source-Based Tree Failure Recovery
Current Iink-state routing protocols such as OSPF or is-is react to Iink failures through Iink-state advertisement and re-computation of the routing table.This involves a convergence process.The convergence process increases router overload,transient loops and slows down reaction to failures.We propose a new routing technique called Source-Based Tree Failure Recovery (STFR),which allows a router to discover a new working path under failure without waiting for completely state consistency in alI routers.The aim Of STFR is to eliminate the convergence process and achieve fast recovery from Iink failures.Our simulation shows that compared to previous work of local recovery methods,STFR can provide better resilience guarantee under failures with low overheads.
