Bit-Oriented Data Link Control Procedures

The rapid growth of data communications in recent years, coupled with a movement from batch-oriented to transaction-oriented (interactive) type of operation, generated the need for a new, more efficient, more reliable, more flexible form of data link control procedure. A bit-oriented approach to data link control that has become the generally accepted standard around the world is discussed in this paper. The basic elements and structure of the procedure are described, some typical examples of operation reviewed, and a "crystal-balling" of the future is offered.
