Introduction to the special issue: ATM systems and networks: basics, issues, And performance modeling and simulation

摘要

Asynchronous Transfer Model(ATM)is one of the major enabling technologies of high-speed net- working. It is the first technology that allows a corporation to use a common enterprise protocol and infrastructure for voice, data, and video communications. ATM excels when applications require specific quality of service(QoS)and reserved bandwidth. It offers economies of scale in network infrastructure by integrating different traffic types. ATM offers a tighter coupling between the user application and network protocol. It places intelligence into the Wide Area Networks(WAN), making the network smarter and allowing the network to become more like a computer and less like a dump transport medium.
