Abstract : |
We present a simple scheme which enables a TCP receiver to distinguish congestion losses from corruption losses. The scheme works in the case where the last hop to the receiver is a wireless link and has the smallest bandwidth among all links on the connection path. We added our mechanism to TCP-Reno to evaluate the performance improvement. We compared our scheme against Ideal TCPReno which is TCP-Reno that can perfectly (but artificially) distinguish between congestion losses and wireless transmission losses. Under favorable conditions, our scheme performs similar to Ideal TCP-Reno and can lead to significative throughput improvement. 1, |
