摘要
动态带宽分配算法是以太网无源光网络系统的关键技术之一,现有采用周期轮询机制的动态带宽分配算法大多存在轮询周期间时隙浪费的问题。文章提出了一种新的消除空闲时间的信道传输方案,理论分析和数值计算证明:新的方案可以有效地消除空闲时间,提高上行链路的利用率。
Dynamic bandwidth allocation algorithm is one of the key technologies in EPON system. Existing dynamic bandwidth allocation algorithms with cycle-polling mechanism mostly have the disadvantage of time wasting between polling cycles .The paper presents a new idle-time eliminating channel transmission scheme. Theoretical analysis and numerical calculation prove that the new scheme can effectively eliminate the idle time and improve the efficiency of upstream link utilization.
