<p>A timed token protocol for use in a local area loop communications network is disclosed. Tre protocol provides three classes of service with a priority reationship between classes. The three classes allow guasnteed bandwidth, interactive and batch services. The classs are implemented by timing the rotation time of a write token to measure instantaneous load. Transmission of inurmation is limited by class of service and the measured vrite token rotation time.</p><p>Also disclosed is a hardware embodiment of a loop communications station which implemerts the timed token protocol.</p> |
