An introduction to loop networks is given,with a summary of previous accomplishments in this area. The problems involved in the transmission of variable-length messages are outlined,and the present technique is shown to be inadequate. An improved variable-length message transmission scheme is proposed for distributed loop computer networks,and a conceptual model is developed of its operation. The model illustrates a method by which the nodal interface can delay incoming messages by hardware buffering just long enough for an outgoing message to be placed on the loop;advantage is taken of gaps between messages to clear out the delay buffer and to make room for future outgoing messages. The effects of the proposed technique on message transmission are discussed,and future research is mentioned. An apendix provides some possible hardware realizations of the model.
