Transmission of high-priority, real-time traffic on low-speed communications links |
摘要 |
<p>A protocol is defined for mixed data/voice/multimedia communications systems to transmit and receive high-priority, real-time traffic over low-speed digital communication links by embedding such high-priority traffic in low-priority, non real-time traffic. High-priority, real-time packets are thus transmitted without delay by preempting low-priority packets. Low-priority, nonrealtime packets are held during preemption, and low priority transmission is automatically resumed after transmission of high-priority 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 this high-priority traffic will be transmitted on the communication link. <IMAGE></p> |
