【摘要】：随着互联网的飞速发展和网络设备的不断更新,当前网络日益暴露出能耗高、效率低、浪费多等诸多问题,因此网络节能问题引起了越来越多的关注。本文基于这种背景,通过合理的设计,提出了基于速度缩放与休眠唤醒相结合的网络节能机制。本文设计并实现了该网络节能机制,该机制共包括四个模块,分别是信息收集模块、流量预测模块、决策模块和拓扑更新模块。信息收集模块分为三个部分,初始拓扑信息的收集、关节点标记和流量信息收集,主要负责对网络的初始拓扑信息进行建立,在此基础上对位置关键的节点进行标记,再将拓扑信息传递给决策模块,同时对网络中的流量进行收集、统计和分析,将流量信息传递给流量预测模块,当网络中的流量突变时,并对决策模块起到反馈的作用。流量预测模块根据收集到的流量信息,使用流量预测算法对网络中的流量进行预测,并将预测的流量信息传递给决策模块。决策模块首先根据信息收集模块中的关节点标记,对网络进行主链路确定,然后当网络中流量减少时,决策模块根据节能算法对网络中的设备进行节能,当网络中的流量增加时,决策模块根据唤醒策略对休眠的设备进行唤醒。拓扑更新模块主要负责当网络设备状态改变或者网络设备出现故障时,对网络中的拓扑情况进行及时的处理,避免路由控制器做出误操作。本文使用Java语言在Eclipse平台上对该网络节能机制设计了可视化界面,将每步关键技术在界面中展示,加深对本设计的了解,并对设计的节能机制进行了能耗和性能的仿真。实验结果表明,本文设计的网络节能机制在不影响网络的性能前提下,可以有效的降低网络的能耗。
[Abstract]:With the rapid development of the Internet and the continuous updating of network equipment, the current network increasingly exposed many problems, such as high energy consumption, low efficiency, much waste and so on. Therefore, more and more attention has been paid to the problem of network energy saving. Based on this background and reasonable design, this paper proposes a network energy saving mechanism based on speed scaling and sleep wake-up. This paper designs and implements the network energy-saving mechanism, which includes four modules, namely, information collection module, traffic prediction module, decision module and topology update module. The information collection module is divided into three parts: the collection of initial topology information, the collection of node marking and traffic information collection, which is mainly responsible for establishing the initial topology information of the network, and marking the key nodes on this basis. Then the topology information is transferred to the decision-making module, and the traffic in the network is collected, counted and analyzed, and the traffic information is transferred to the traffic prediction module. When the traffic in the network changes suddenly, it plays a feedback role to the decision-making module. According to the traffic information collected, the traffic prediction module uses the traffic prediction algorithm to predict the traffic in the network, and transmits the traffic information to the decision-making module. The decision module first determines the main link of the network according to the node mark in the information collection module, and then, when the flow in the network is reduced, the decision module saves energy on the equipment in the network according to the energy-saving algorithm. When the traffic in the network increases, the decision module wakes up the dormant devices according to the wake-up strategy. The topology update module is mainly responsible for the timely processing of the topology in the network when the state of the network equipment changes or the network equipment fails to avoid the wrong operation of the routing controller. In this paper, the visual interface of the energy saving mechanism of the network is designed by using Java language on the Eclipse platform. The key technologies of each step are displayed in the interface to deepen the understanding of the design, and the energy consumption and performance of the energy saving mechanism are simulated. The experimental results show that the energy saving mechanism designed in this paper can effectively reduce the energy consumption of the network without affecting the performance of the network.
