摘要
研究了基于争用/预约机制的混合光纤/同轴宽带接入网媒体接入控制协议原理,提出了随机争用与周期查询排队系统相结合的终端申请接入方式,使不同优先级的终端申请能以不同的控制机制实现接入。计算机仿真实验结果表明,系统能保证具有较高优先级的申请能获得更好的服务质量保证。
Based on the study of HFC MAC protocol over contention/reservation scheme, an efficient method, which worked on random contention and polling model has been proposed in this article to meet the needs of a multi-priority service access control system. The computer simulating shows the service with higher priority would have the better performance of throughput and delay.
