System for message traffic control utilizing prioritized message chaining for queueing control ensuring transmission/reception of high priority messages

摘要

An on-line data processing system for providing a traffic control over the message queuing buffers that temporarily store the messages in order to absorb the difference in the message processing speed between the on-line program processing unit and the transmission/reception unit connected to a plurality of terminals. The traffic control is provided such that the message is stored or obtained in or from the message queuing buffer in accordance with the priority set on the messages. The priority of the messages is determined by using a character string in a predetermined position in each message.
