Queueing Analysis for ATM Switching of Mixed Continuous-Bit-Oriented and Bursty Traffic

In this paper, mixed Continuous-Bit-Oriented (CBO) and bursty traffic contending for transmission on any output line of a broadband switch based on Asynchronous Transfer Mode (ATM) is modeled as a superposition of traffic from a number of independent random and binary sources. With the use of a recursive algorithm, a complete queueing analysis is presented. The queue length distribution, the delay distribution, and the cell loss probability for a finite buffer system, are all exactly calculated. The two cases when the delay priority is given to CBO traffic and the loss priority is given to either traffic respectively are also presented.
