随着高清IPTV、在线游戏等业务的发展,用户对于带宽的需求日益增加,10G-EPON技术应运而生。与传统的EPON系统一样,10G-EPON系统的动态带宽分配问题仍然十分关键。带宽分配方式的选择对于如何避免传输冲突,提高系统的带宽利用率且保障服务质量都非常重要。在已有算法的基础之上,提出一种改进型动态带宽分配算法。该算法重点确保高优先级业务的服务要求,在一定程度上体现了不同等级ONU之间的公平性,提高了上行带宽利用率。
With the development of high-definition IPTV, online games and other services, the demand for bandwidth is increasing day by day. 10G-EPON technology has emerged. As with traditional EPON systems, the dynamic bandwidth allocation of 10G-EPON systems is still critical. The choice of bandwidth allocation mode is very important for how to avoid transmission conflicts, improve system bandwidth utilization and ensure service quality. Based on the existing algorithms, an improved dynamic bandwidth allocation algorithm is proposed. The algorithm focuses on ensuring the service requirements of high-priority services, to a certain extent, reflects the fairness between different levels of ONUs and improves the utilization of upstream bandwidth.
