Analysis of a Buffered Floating-Threshold Hybrid Switching System

We describe a model of a floating-threshold hybrid switching data transmission system. Unlike previously studied models, our model assumes that priority (channel-switched) calls are not lost, and remain waiting until a channel is freed. An algorithm of exact numerical computation of stationary characteristics is given, the high-traffic behavior of the system is determined, and simple bounds on the average characteristics of the queueing process are obtained.
