Abstract
Unlike conventional circuit-switched communication systems, a packet-switched network provides communication paths among its customers which exhibit time-varying throughput and delay characteristics. To successfully communicate with speech through such a network the speech must be compressed to an average data rate which the network can almost always handle and a smoothing algorithm must be used at the receiver to eliminate most of the jitter in packet arrival times. The smoothing process introduces further delay in a communication system that inherently has greater delay than conventional circuit-switched systems. The tradeoff between delay and “glitches” caused by late arrival of packets suggests a compromise which allows some glitches (perhaps 1% to 2%). Recent experiments with the ARPANET, a network designed for data communication among computers, have demonstrated that successful speech communication can take place in a packet-switched network.
