ABSTRACT:
A random multiple-access communication system operates both a feedback-ignored (e.g. ETHERNET) and a feedback-utilized (e.g. STACK) protocol simultaneously. The system is useful for communicating two types of information such as voice and data wherein one of the information types (e.g. voice) is subject to delay constraints. The feedback-utilized protocol has the effect of taking priority over the feedback-ignored protocol in the communication system to provide a priority transmission system.
