高速网实时通信的调度能力

Real-time communication schedulability in high-speed networks

提出了一种通用实时连接调度模型 .在抢先最早预定日期调度策略下 ,给出了任意网络结点上实时连接调度能力的充分必要条件 .在实时通信服务中 ,这些条件形成了 Qo S确定性保证的数学基础 .

A generalized real time connection schedule model is presented.The necessary and sufficient conditions are given for the schedulability of real time connections at each network node under preemptive earliest due date scheduling policy.These necessary and sufficient conditions form the mathematical basis for the deterministic QoS guarantees in real time communication services.
