Abstract(in English) This paper investigates the traffic performance of ATM Adaptation Layer 2 (AAL2) cell assembly and disassembly (CLAD) by an analytical method where AAL2 is standardized to convey low-bit-rate traffic such as mobile traffic including IMT-2000. In particular, it evaluates the number of channels that can be multiplexed in the fixed capacity output link of AAL2 CLAD for various timeouts and buffer sizes. The arrival process is modeled as a discrete Markovian arrival process considering the talkspurt and silence period of a voice source, and discrete-time tandem queues modeling a cell assembly queue and a transmission queue are analyzed. Approximation models and their accuracy are also investigated and the Independence approximation is shown to be good for accuracy and computation time.
