THE ROLE OF ATM TECHNOLOGY IN FUTURE DATA COMMUNICATION SYSTEMS
S. S. Riaz Ahamed · 2008
Demand for quick access to Web-based applications and real-time delivery of multimedia transmissions via an integrated network infrastructure drives implementation of ATM (Asynchronous Transfer Mode) broadband solutions. ATM is a high-performance technology that provides bandwidth on-demand for seamless transport of full-motion video, audio, data, animations, and still images in local and wider area environments. Asynchronous transfer mode (ATM) is a cell-oriented switching and multiplexing technology that utilizes fixed-length packets to carry different types of traffic and also ATM will enable carriers to capitalize on a number of revenue opportunities through multiple ATM classes of services; highspeed local-area network (LAN) interconnection; voice, video, and future multimedia applications in business markets in the short term; and in community and residential markets in the longer term. ATM reduces infrastructure costs through efficient bandwidth management, operational simplicity, and the consolidation of overlay networks. Carriers can no longer afford to go through the financial burden and time required to deploy a separate network for each new service requirement (e.g., dedicating a network for a single service such as transparent LAN or frame relay). ATM technology will allow core network stability while allowing service interfaces and other equipment to evolve rapidly.
