Route Caching: Beware! Stale caches can adversely affect performance With passage of time and host mobility, cached routes may become invalid A sender host may try several stale routes (obtained from local cache, or replied from cache by other nodes), before finding a good route An illustration of the adverse impact on TCP will be discussed later in the tutorial [Holland99] 57
