绿色网络和绿色评价:节能机制、模型和评价

Green Network and Green Evaluation:Mechanism,Modeling and Evaluation

随着网络规模的扩大和网络设备的不断更新,目前的网络对能量的利用日益暴露出能耗高、效率低,浪费多等诸多问题.节省网络能耗、构建绿色网络不仅成为计算机领域一个意义重大、需要迫切解决的课题,也成为影响社会可持续发展和国家发展战略的一个重要因素.目前,大量绿色网络的研究工作致力于减少网络系统的无用能耗,提高能量利用率.文中将能量看成一种系统资源,从资源分配和任务管理角度对绿色网络的机制和策略进行了综述,介绍了模型方法在绿色评价中的应用.基于这些讨论,文中提出了基于随机模型的绿色评价框架,为构建绿色网络和节能机制的评价体系奠定了基础.

With the expanding of network size and the update of network equipments,energy utilization of network has increasingly exposed high energy consumption,low efficiency and high waste problems.Saving network energy and building green network has become not only a significant research topic which needs to be solved urgently,but also an important factor affecting the sustainable development of the society and the national development strategy.At present,a large number of green network research make efforts to reduce unnecessary energy consumption of network systems to enhance energy efficiency.The authors treat energy as a kind of system resources,review the green network mechanism and strategy from the perspective of resource allocation and task management,and introduce the modeling methods in green network applications.Based on these discussions,this paper presents an evaluation framework based on stochastic theoretical model,to lay the foundation of construction the performance evaluation system for green networks.
