In this paper we introduce a cross-layer mechanism to enhance the effectiveness of link-state routing protocols by providing a localized estimate of the validity of a given route. Accurate predictions of route staleness result in less packet loss by selecting alternative paths before primary path failures. We present a proof of concept implementation that utilizes shared location and velocity i...

Internet transmission and switching facilities are partitioned into different administrative domains. To effect routing between domains, domain border routers establish pairwise peering sessions and exchange routing information at exchange points. An alternative arrangement, in which each border router at an exchange point peers only with a Route SerÕer, provides some operational benefits. From...
