| 摘 要： | 上行带宽的动态带宽分配是以太网无源光网络(EPON)系统的一个重要研究领域,文章提出了一种区分业务优先等级的动态周期轮询算法.该算法保证了高优先级业务的实时传输,同时为中、低优先级业务提供了基本的带宽,兼顾了动态带宽分配的效率和公平性.文中通过公式推导,给出了算法的具体实现过程,从理论上证明了新算法的可行性.

| Abstract: | Dynamic Bandwidth Allocation(DBA) of the upstream bandwidth is crucial in EPON systems.In this paper,a service priority-based dynamic polling with adaptive cycle scheme is introduced.It ensures the real-time transmission of high priority services and provides basic bandwidths to the low-and medium-priority services with the efficiency and fairness of the dynamic bandwidth allocation guaranteed.The specific implementation of the scheme is described by formula deduction and the feasibility of the new DBA scheme is theoretically proved. |
