Voice Flow Control in Integrated Packet Networks
Abstract
Packet-switched networks are used primarily to handle data traffic, but considerable interest has recently been generated in extending packet- switching methods to also handle digitized voice traffic. New network control procedures are needed to deal with packetized voice traffic, as its characteristics are different from regular data traffic. We present two flow control algorithms which can be executed in a distributed manner to adjust source rates according to prevailing network conditions. Although the algorithms were developed for packet-voice networks, they are quite general and are applicable to many other systems. One algorithm is based on an optimization theoretic formulation of the flow control problem. The other has as its major premise a specific notion of fairness. Convergence is shown for both algorithms under static conditions. A program is developed which simulates the behavior of a general packet-switched network on an individual packet basis. It is used to examine the performance of the second flow control algorithm under realistic conditions.
