Abstract: The time-overhead introduced with the performance of ATM end-to-end signaling operations is an important performance factor that determines the service quality. A significant time-overhead associated with the high-rate establishment and release of many short-lived data channels, required in various multimedia applications, would result in network performance degradation. This paper presents traffic experiments conducted in a local area ATM network for the timing evaluation of end-to-end signaling operations. Timing results that quantify the introduced delays under diverse conditions of signaling loud and traversed nodes are provided. Unexpected results and factors that may intensely affect the signaling performance are presented.
