Abstract: A protocol is defined for mixed data/voice/multimedia communications systems to transmit and receive high-priority, real-time traffic over low-speed digital com munication links by embedding such high priority traffic in low priority, non-real-time tra ffic. High priority, real-time packets are thus transmitted without delay by preempting low -priority packets. Low priority, non real-time packets are held during preemption, and low priority transmission is automatically resumed after transmission of high priori ty packets has been completed. A protocol is defined for communications systems to exchange information, at the time that a communication link is activated, defining their link capabilities for handling high priority, real-time packets and to agree on how t his high priority traffic will be transmitted on the communication link.
