RTT Last modified: Thursday, March 28, 2002
(1) Short for real-time technology. RTT refers to technology that allows a user to receive data during the actual time that a physical process occurs, known as real time. Real time is measured in milliseconds or microseconds. While RTT is used for sophisticated entertainment purposes, such as streaming live video or audio and has applications that ultimately will make Internet use more lively and practical, this immediate-response technology is being used for a wide array of critical applications that require instant response times. For example, an automatic pilot must respond to data on changing flight conditions or the position of other aircraft immediately; nuclear power plants must have real-time information on what is happening at all times in all critical areas of the plant for safety; space flight computers must respond instantly to changing conditions in the atmosphere. (2) Short for round-trip time, the time required for a network communication to travel from the source to the destination and back. RTT is used by some routing algorithms to aid in calculating optimal routes.
