Delay versus TASI advantage in a packet voice multiplexer
Abstract
The delay characteristics of the packet-voice-multiplexer model described by Janakiraman et al. (1980, 1981) are investigated numerically and illustrated in a graph of mean queuing delay versus buffer size. It is demonstrated analytically that the time-assignment-speech-interpolation (TASI) advantage provided by a packet system (relative to conventional circuit-switched TASI) is increased if voice-unit delays can be tolerated, confirming the simulation findings of Weinstein and Hofstetter (1979).
