Jitter analysis and simulation of constant bit rate ATM multiplexers

ATM is a standard transport mechanism to integrate various services such as data, voice, image and video in a single network. Constant bit rate (CBR) and variable bit rate (VBR) are the major sources in ATM networks. Such sources may have stringent delay and loss requirements. Clearly, if the network is not properly designed, dimensioned, and controlled, extensive cell delay and cell delay variation or jitter may deteriorate the performance of the network to an unacceptable level. This paper analyzes and simulates the jitter in a CBR and cell based multiplexer. The effects of various parameters such as the background traffic streams, periodic traffic, and utilization are investigated.
