Open Issues and Challenges in Providing Testing and Signaling in High Speed ATM Networks

Testing Asynchronous Transfer Mode (ATM) communications and network equipment is the function of performing the testing phases required for complete evaluation of ATM products. The test phases measure and analyze all aspects of ATM - from the characteristics of lower-layer cell transmission through to the complex ATM services used to transmit multimedia over ATM networks. ATM technology has become inextricably linked to promises of a global communications infrastructure. The expectation is that seamless integration of voice data and video across high-speed ATM links will provide universal access to multimedia services. ATM equipment developers, service providers, and end users are all faced with these same challenges when testing ATM products.
