Abstract:

In this paper we present a new error control approach for continuous media communication protocols. Since continuous media data are inherently bursty, these protocols commonly use a control time for the first packet in a burst to ensure continuous playback in the presence of delay jitter. The retransmission scheme presented in this paper, which is called Slack Automatic Repeat Request (S-ARQ), is based on appropriately extending the control time for the first packet in a burst to allow for the timely retransmission of lost packets, i.e., before the lost packet is due for playback. We present simulation results that demonstrate the feasibility and effectiveness of this retransmission scheme under a realistic scenario for an FDDI network.
