【摘要】：在如今的网络中过大的能量消耗问题已经引起了社会的广泛关注,过大的能耗不仅增加了网络的运营成本,更会对全球环境造成极大影响。因此,近些年来,各种网络节能技术成为了业界的研究热点。但是由于种种原因,在传统的网络中难以从根本上解决网络能耗过大的问题,所以必须要重新设计一种全新网络架构体系,这一类全新的网络我们统称为未来网络。在新的网络架构下网络休眠方案是解决网络能耗过大的重要方法之一,本文是以未来网络为研究背景,对未来网络中的休眠机制进行研究。本文首先阐述了未来网络以及未来网络休眠机制的研究背景和研究意义,突出强调了构建环保节能的未来网络的迫切性,分析了国内外对于未来网络以及未来网络下休眠机制的研究现状以及取得的一些重大研究成果。然后文章对未来网络和未来网络下休眠方案进行了综述,分析了几种现如今主流的未来网络架构,并且分析了各个网络的起源以及适用场景等。重点研究了在主流未来网络下的休眠机制,分析并比较了各个网络下的休眠方案的优劣性。随后本文选取未来网络中Openflow网络以及DTN网络为代表,着重研究在这两个网络下休眠方案。在Openflow网络中,本文研究了在该网络架构下的节点休眠方案和链路休眠方案,给出了具体的算法流程,并且根据仿真结果分析了两种休眠方案的节能效果。在DTN网络中,我们研究了该网络架构下的自适应异步时钟休眠方案,重点研究了基于循环差集的EACDS算法和MACDS算法,并且根据仿真结果分析算法的节能效果以及算法中不同休眠等级对网络运行的影响。最后本文对研究未来网络下的休眠机制进行了总结和展望。
[Abstract]:Nowadays, the problem of excessive energy consumption in the network has attracted wide attention of the society. Too much energy consumption not only increases the operating cost of the network, but also has a great impact on the global environment. Therefore, in recent years, a variety of network energy-saving technology has become a research hotspot in the industry. However, for various reasons, it is difficult to fundamentally solve the problem of excessive network energy consumption in the traditional network, so we must redesign a new network architecture system, this kind of new network we call the future network. Under the new network architecture, network dormancy scheme is one of the most important methods to solve the problem of excessive network energy consumption. In this paper, the sleep mechanism in future network is studied based on the future network. This paper first describes the research background and significance of the future network and the future network dormancy mechanism, and emphasizes the urgency of constructing the future network of environmental protection and energy saving. This paper analyzes the current situation of future network and its dormancy mechanism at home and abroad, as well as some important research achievements. Then, this paper summarizes the future network and future network dormancy schemes, analyzes several kinds of current mainstream future network architecture, and analyzes the origin and applicable scenarios of each network. This paper focuses on the dormancy mechanism in the mainstream future network, and analyzes and compares the advantages and disadvantages of the sleep schemes in each network. Then this paper chooses the Openflow network and the DTN network as the representative, and focuses on the dormancy scheme under these two networks. In the Openflow network, this paper studies the node sleep scheme and the link sleep scheme under the network architecture, gives the specific algorithm flow, and analyzes the energy-saving effect of the two sleep schemes according to the simulation results. In the DTN network, we study the adaptive asynchronous clock sleep scheme under the network architecture, and focus on the EACDS algorithm and MACDS algorithm based on cyclic difference set. According to the simulation results, the energy-saving effect of the algorithm and the effect of different hibernation levels on the network operation are analyzed. Finally, this paper summarizes and prospects the future network dormancy mechanism.
