PERFORMANCE OF TIME-DIVISION MULTIPLE-ACCESS ALGORITHM FOR PASSIVE STAR NETWORKS USING ASYNCHRONOUS TRANSFER MODE

A time division multiple access algorithm is studied that is particula rly optimized for the scheduling of packet transmission in an Asynchro nous Transfer Mode (ATM) operating passive star network. It is based o n a constant bit rate (CBR) reservation scheme. Periodically generated time slot reservations are queued in a global slot reservation queue and served according to the first-in-first-out discipline. The queuein g delay calculations using a Markov chain description of the algorithm show excellent agreement with experimental values obtained by a hardw are model. It is suggested that by using the CBR reservation scheme in stead of a variable bit rate reservation the performance of the passiv e star network may significantly be enhanced.
