摘要:
 信息通信技术的发展为人们的生活提供了便利,但同时带来了巨大的能源浪费。网络虚拟化允许在共享的物理网络上运行多个虚拟资源,大大提高了物理网络的能源效率。先前研究工作的主要目标是通过在同一物理资源上供应更多的虚拟网络请求,最小化物理资源花费的成本,从而最大化ISP的收益。目前,已有研究人员将节能技术应用于虚拟网络,提出改善基于成本的虚拟网络映射( VNE)算法,旨在降低能耗。文中主要对虚拟网络架构中的能效优化技术和方法进行研究,包括休眠机制、动态适应、比例计算、选择性连接和网元等级化,分析了虚拟网络映射中的能效优化。重点研究了能量感知VNE,并展望未来的研究工作和面临的挑战。
Abstract:
 The development of information communication technology brings not only convenience to people’ s life,but also great energy consumption and waste of network resources. Network virtualization,which enables multiple virtual resources to run in the shared underly-ing network,greatly improves the energy efficiency of physical network. The major goal of the previous study is to supply virtual network requests as many as possible on the same physical resources,to minimize physical resources cost,so as to maximize the benefits of ISP. In order to reduce energy consumption,energy-saving technologies of network and modification of VNE algorithm based on cost has been introduced to virtual network. It focuses on the energy-saving technologies and methods for virtual network architecture in this paper,in-cluding sleeping mechanism,dynamic adaptation,scale computation,selective connection and hierarchical network element. The energy-efficiency optimization in VNE was analyzed. Focus on the energy-aware VNE and look forward to the future research work and challen-ges at last.
