ATM (asynchronous transfer mode)
A wide-area network (WAN) technology. ATM is a transfer mode for switching andtransmission that efficiently and flexibly organizes information into cells; it isasynchronous in the sense that the recurrence of cells depends on the required orinstantaneous bit rate. Thus; empty cells do not go by when data is waiting. ATM'sflexibility lies in its ability to provide a high-capacity; low-latency WAN switchingfabric that is protocol-; speed- and distance-independent; and that can supportmultiple types of information (including data; video; image and voice). The greatestbenefit of ATM is its ability to provide support for a wide range of communicationsservices while providing transport independence from those services.
