New techniques for making transport protocols robust to corruption-based loss
Current congestion control algorithms treat packet loss as an indication of network congestion, under the assumption that most losses are caused by router queues overflowing. In response to losses (congestion), a sender reduces its sending rate in an effort to reduce contention for shared network resources. In network paths where a non-negligible portion of loss is caused by packet corruption, performance can suffer due to needless reductions of the sending rate (in response to "perceived congestion" that is not really happening). This paper explores a technique, called Cumulative Explicit Transport Error Notification (CETEN), that uses information provided by the network to bring the transport's long-term average sending rate closer to that dictated by only congestionbased losses. We discuss several ways that information about the cumulative rates of packet loss due to congestion and corruption might be obtained from the network or through fairly generic transport laye...
