Performance Analysis of Hybrid Switching Concepts for Integrated Voice/Data Communications

Abstract

This paper describes and evaluates variations of a generic hybrid switching concept for integrated voice and data communications. Concepts examined include the Slotted Envelope NETwork approach, the enhanced hybrid (SENET) with time assignment hybrid, and the variable length frame/packet approach. Primary criteria used to evaluate the concepts are transmission throughput efficiency and delay versus information throughput. Other criteria, such as voice continuity and routing/flow control, were also applied.
