Asynchronous Transfer Mode (ATM)
The technology of asynchronous transfer mode was developed in the telephone industry in the 1980s at the major telephone research laboratories. The goal was to develop a networking technology that could carry an integrated mix of traffic (voice, video and data). At one point, there were two competitors to be the technology of choice, synchronous transfer mode (STM) and ATM. Asynchronous transfer mode was the eventual winner.
