In this chapter, traffic performance in Flow-Aware Networks in the event of a link failure is analyzed. The main assumption is that streaming flows should be quickly accepted in a link and immediately redirected to a backup link when a failure occurs. Two solutions to overcome the problem of long-waiting times for flows to be accepted on new routes are presented in this chapter, namely the GPFL (Global Protected Flow List) and a multilayer recovery strategy whose operation is based on the EHOT (Enhanced Hold-Off Timer) algorithm. The flow-aware resilient ring (FARR) is also discussed here.
