摘要: 针对移动网络中新的增值数据业务的增加、性能指标多样化的现状,提出了一种具有共享缓存、支持可变比特率业务的接入网系统模型,给出了性能参数的计算方法、兼顾分组层性能参数(丢包率和平均时延)和连接层性能参数的CAC算法,数值计算结果表明了该方法的正确性。

Abstract: As more and more value-added data services are devoloped which require complex quality of service(QoS), this paper defines a wireless access network model with shared buffer and derives mathematical expressions for some QoS parameters. It proposes a joint CAC algorithm considering both packet-level QoS and connection-level QoS. The numerical results proves correctness of the method.
