In order to manage Quality of Service (QoS) and energy efficiency in the optical access network, an online Dynamic Bandwidth Allocation (DBA) algorithm with adaptive sleep cycle is presented. This DBA algorithm has the ability to allocate an additional bandwidth to the end user within a single sleep cycle whose duration changes depending on the current buffers occupancy. The purpose of this DBA algorithm is to tune the duration of the sleep cycle depending on the network load in order to provide service to the end user without violating strict QoS requests in all network operating conditions.

WDM EPON中具有自适应睡眠周期的在线DBA算法分析

为了管理光接入网络中的服务质量（QoS）和能源效率，提出了一种具有自适应睡眠周期的在线动态带宽分配（DBA）算法。这种DBA算法具有在单个睡眠周期内为最终用户分配额外带宽的能力，该睡眠周期的持续时间根据当前缓冲区占用率而变化。此DBA算法的目的是根据网络负载调整睡眠周期的持续时间，以便为最终用户提供服务，而不会在所有网络操作条件下违反严格的QoS请求。
