摘 要: 实时业务是ATM网络中一类重要的业务,相对于非实时业务这类业务有更严格的服务质量要求.好的复接器调度策略是实时业务服务质量的一个重要保证.本文提出一种调度实时业务的新方法,给出并证明了该方法可调度的充分必要条件.该方法在大大降低复接器工作量的同时,保证了较高的频带资源利用率,将对实时业务的传输控制产生积极的影响. As a major element of services in ATM networks,realtime services have more stringent requirments for quality of service (QoS) than nonrealtime services.A good scheduling method is crucial for guaranteeing the QoS of realtime services.In the paper,a new scheduling technique for realtime services is proposed.Exact schedulability condition is also presented.The new method can reduce the workload of scheduler and provide high utilization of frequence resources.
