This paper presents a performance study of ATM Network in the support of real-time MPEG-I video transmission. Multiple classes of MPEG-I will be used in the study and what makes this simulation study different from the others is the video data we used. These data are captured from real video programmes and we categorized these video clips according to their workload characteristics. The performance of the ATM switch is examined in terms of the cell miss ratio due to deadline missing and the cell loss ratio due to buffer overflow in both the ATM switch as well as the gateways. Moreover, a higher level of abstraction in terms of burst loss ratio will also be collected. The results indicated that the first-come-first-serve scheduling algorithm is insufficient to handle real-time traffic. This paper presents a better method to improve the performance significantly especially when the virtual path bandwidth negotiated is conservative.
