摘要

基于在线-离线双子周期混合调度方式和节点模块化的设计思想,提出一种支持区分服务的节能动态波长带宽分配算法。该算法综合考虑光线路终端(OLT)和光网络单元(ONU )两端节能机制的相互影响以及不同类别业务的时延和带宽约束条件,利用在线子周期和离线子周期分别为加速转发业务和确保转发/尽力而为业务授权。每个子周期内通过合理选择波长信道和传输窗口,尽可能减少激活波长数,延长节点处于低功耗状态时间,减少节点状态转换次数,避免信道出现高能耗空隙,以降低全网能耗。仿真结果表明:所提算法在保证业务不同约束要求的前提下,有利于降低ONU、OLT端能耗和全网总能耗。

Abstract

Based on the hybrid scheduling with online and offline double polling sub-cycles and node modularization design, an energy-saving dynamic wavelength and bandwidth allocation algorithm supporting differentiated services is proposed. Considering the interaction of energy-saving mechanisms at optical line terminal (OLT) and optical network unit (ONU) and the different delays and bandwidth constraints for different types of traffics, the algorithm uses online and offline sub-cycles to authorize the required bandwidth for expedited forwarding traffic and assured forwarding/best effort traffic, respectively. In each sub cycle, the energy consumption is reduced by reasonably allocating the wavelength channel and transmission window to minimize the number of active wavelengths, extending the low-power duration of nodes, reducing the number of state transitions at nodes and avoiding the high energy consumption voids of channels. The simulation results show that the proposed algorithm can reduce the energy consumption of ONU and OLT and the network’s total energy consumption while guaranteeing the specific constraints of different types of traffics.
