摘要
针对互联网中业务流量的动态变化,提出了基于预置多拓扑的节能算法.首先根据历史的业务流量数据将每天划分为多个时间片,然后在划分好的各个时间片内利用邻域搜索作节能子拓扑设计.通过优化链路权重向量使流量集中在部分链路上,同时休眠没有流量经过的链路,以实现互联网节能的目标.
To solve the problem that the traffic flow dynamically changes in Internet protocol（ IP） network,a new energy saving algorithm based on pre-configured multiple topologies（ ESPMT） was proposed. In the ESPMT algorithm,firstly,according to the daily traffic flow,each day is divided into multiple time slices,secondly,the energy-saving sub-topology is designed by utilizing neighboring region search for each single time slice. To achieve the purpose of energy saving,the traffic flows are concentrated on some links. The links without traffic are powered off in IP networks.
