Abstract :
Mixed continuous-bit-rate (CBR) and bursty traffic contending for transmission on any output line of a broadband switch based on the 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 queuing analysis is presented. The queue length distribution, the delay distribution, and the cell loss probability for a finite buffer system are exactly calculated. Cases considered and analyzed include: delay priority for CBR traffic, absolute cell loss priority for DS1/DS3 emulation or guaranteed bandwidth CBR traffic with a stringent cell loss requirement, and threshold cell dropping for voice CBR traffic with a high degree of cell loss tolerance
