| 摘 要： | 针对现有宽带无线网络中日益详细的业务分级,提出了基于分级业务的权重公平自适应接纳控制算法W FAC,在始终接纳高权重业务的同时,使各个低权重业务的接纳率比例与其权重比例基本相同.仿真结果表明,自适应算法可以根据当前的带宽资源和负载自适应的改变接纳策略,对各种分级业务表现出明显且合理的区分.在保持高带宽利用率的同时,合理地控制低权重业务,避免已接纳的高权重业务降级.

| Abstract: | A weighted fair adaptive admission control(AC) algorithm based on classified services(WFAC) is presented for increasingly detailed QoS(quality of service) definition in practical BWA(broadband wireless access) network.This algorithm always admits heavy weight services while admitting light weight services in the manner of weighted fair.The simulation results demonstrate that the adaptive algorithms can adaptively shift admission strategy based on current bandwidth resource and system load,obviously and reasonably classify service flows by their weight.Furthermore,the algorithm rationally restricts the services with lighter weight to avoid degrading admitted services with heavier weight while holding high bandwidth utilization. |
