Other Methods of Dealing with Congestion

Other Methods of Dealing with Congestion. Outline New Reno SACK TCP Vegas RED. Motivation for improving RENO. Recall from Internet traffic lecture that packets area often transmitted in bursts Thus, losses also often happen in bursts Due to FIFO (drop tail) queues in routers
