In certain contemporary ring networks data processing stations communicate as peers by transmitting information in structured variable-length frames containing header and terminal control portions of predetermined length. In such systems, each "informational" frame sent from an "origin station" to a specific "destination" station (such frames containing data or control information) must be specifically acknowledged by a response frame sent from the same destination station to the origin station. The origin station will not send another informational frame to the same destination until it receives an acknowledgment indicating correct reception of the previous frame.
