Adaptive playout mechanisms for packetized audio applications in wide-area networks

摘要: Recent interest in supporting packet-audio applications over wide area networks has been fueled by the availability of low-cost, toll-quality workstation audio and demonstration that limited amounts interactive can be supported today's Internet. In such applications, received packets are buffered, their playout delayed at destination host order to compensate for variable network delays. The authors investigate performance four different algorithms adaptively adjusting delay an terminal application, face varying They evaluate using experimentally-obtained measurements traffic between several Internet sites. Their results indicate adaptive algorithm which explicitly adjusts sharp, spike-like increases packet were observed traces achieve a lower rate lost both given average maximum buffer size. >
