N2 - This paper presents a performance study of ATM networks in support of multi-media traffic with different real-time requirements. The performance of the ATM switch is examined in terms of cell missing ratio due to missed deadlines, and cell loss ratio due to buffer overflows, in both switches and gateways. A higher level of abstraction in terms of burst loss ratio will also be included. The results indicate that a first-come-first-serve scheduling algorithm is insufficient to handle real-time traffic. This paper presents a better method, that significantly improves the performance, especially when the negotiated virtual path bandwidth is conservative.
