Analysis of Packet Delay for an Integrated Voice-Data System

Abstract

The performance of an integrated voice-data system using a movable boundary multi-plexing scheme is analyzed. In this scheme, channel time is divided into slots, grouped into equal length frames. A voice call arriving in a slot is served in the next frame, whereas a data packet is served in the next available slot. Voice calls are blocked calls cleared, while data packets may be buffered. Our approach is based on a discrete-time queueing model with periodic interruptions. An exact analysis of the average delay for data packets is given. The bounds of this delay time are also discussed.
