摘要
为缓解数据中心网络传输压力,提出一种光电数据共传方案。采用MEMS(micro-electro-mechanical system)和WSS(wavelength selective switch)光器件,在电域网络基础上构建光电混合网络,根据流量需求信息在大流量路径建立光链路,基于目的地址进行路径流量预测,为光链路的建立和撤除提供决策服务。构建光电传输代价矩阵,给出光链路对附近链路数据搭载的方法,缓解周围链路传输压力。仿真结果表明,该网络能有效应对网络流量的变化,保持光链路的高效利用,验证了网络的性能。
To alleviate the pressure of data center network,a scheme for data transmission was presented.By using MEMS（micro-electro-mechanical system）and WSS（wavelength selective switch）,a hybrid network was built based on the electric network.Optical links were established between nodes with large traffic demands.Flow size was predicted according to destination address,which provided information for the establishment and removal of optical links.The scheme of optical link carrying data was proposed based on the cost matrix,which reduced the transmission of other links.The results show that the hybrid network has good performance,which verifies that the network structure is reasonable.
