| Abstract(in English) | A cell-discard method has been developed for use on networks supporting TCP-over-ATM traffic with an unspecified bit rate. In this "concentrated celi discard" (CCD) method, when an ATM switch becomes congested, consecutive cells are discarded from the front of the bufter, and cell discarding is suspended for a specified period of time. Using this method prevents TCP timeouts, which is a main reason for decreasing TCP throughput in today's TCP over ATM networks, and shorten the time being congested by avoiding the long delay experienced with TCP fast-retransmission algorithm before the transmitters TCP receives duplicate acknowledgments. Even though CCD does not consider TCP packet boundaries, throughput with CCD was found by computer simulation to actually be higher than with early packet discard. |
