Combining two media access protocols to support integrated traffic on high data rate networks

Abstract

The paper describes the operation and performance of an integrated traffic network using separate media access protocols to support different traffic types on a single unidirectional ring or bus. One protocol, based upon local carrier sensing (CSMA/RN) provides access for asynchronous traffic; the other, a 'train like' protocol called the circulating reservations packets (CRPs), provides access for synchronous voice and video traffic. Other media access protocols like slotted ring or QPSX are equally applicable for use as the asynchronous protocol.<>
