Abstract

Internet multimedia applications have different requirements than do traditional text-based applications, placing new demands on TCP and UDP, the dc-facto Internet transport protocols. We propose a Selective Retransmission Protocol (SRP) to balance the potentially high loss found in UDP with the potentially high latency found in TCP. SRP uses an applicationspecific decision algorithm to determine whether or not to ask for a retransmission for a lost packet, adjusting the loss and latency to the optimum level for the application. We develop and experimentally evaluate an audioconference using SRP on a wide-area network testhed. We find SRP outperforms both TCP and UDP in terms of multimedia application quality.
