摘要

为有效解决绿色无源光网络中的节能效果与时延性能的矛盾，提出一种支持 ONU 模块独立不连续收发数据的节能方法。通过光网络单元的模块化，各能耗模块独立地切换睡眠或唤醒模式，从而在规定时隙内实现不连续地收发数据；通过子周期划分，将实时业务集中到第一个子周期内收发，提升了网络的总体服务质量；提出完全独立的上下行带宽分配算法，使所提方法在流量上下行不对称的应用场景更具优势。仿真表明，所提方法在保证业务时延性能的前提下，网络的能耗得到进一步降低。

Abstract

To effectively solve the contradiction between energy-saving and packet delay performance in green passive optical network

an energy-saving scheme supporting ONU modularization with independent-discontinuous transceiving is proposed.Utilizing the technology of optical network unit modularization

each module could switch to sleep or awake mode independently and transmit data in specified time slots discontinuously.Simultaneously

to enhance the quality of service of the overall network

the real-time packets are transmitted in the first sub-cycle based on the sub-cycle division strategy.Furthermore

an independent bandwidth allocation algorithm is proposed

which makes the scheme have more advantages in the asymmetric network traffic scenarios.Simulation results verify that the proposed scheme further reduce the network energy consumption on the premise of guarantee the packet delay.
