About ATM Asynchronous Transfer Mode (ATM) is a connection-oriented
cell-based transport mechanism that allows very high-speed transfer
of data, voice, and video from one point to another. An ATM network
consists of a series of switches that connect one end of a virtual
circuit to another. These switches use virtual path identifiers and
virtual circuit identifiers to direct cells as they travel. Cells are
switched onto paths operating at up to gigabit-per-second
transmission speeds.
