基于自动网络加速器的云计算能耗降低的方法研究

Research on Lower Energy Consumption of Cloud Computing with Automatic Network Accelerator

虚拟计算机在云计算中被广泛使用时,会导致用户到服务器的距离比以前更长,引起虚拟计算机的性能退化,这会带来服务质量的恶化和ICT(information communication technology)设备能源消耗的增加;针对该问题,提出了把网络加速器自动应用到云计算网络中的方法;为了使用当前主流的网络加速器,方案采用了基于mSCTP的数据传输,该协议在迁移前后使用不同的传输控制协议(TCP)连接的;文章没有考虑动态迁移本身会使虚拟计算机的性能退化,实验结果表明,虽然需要安装网络加速器作为云资源的一部分并暂时地增加通信链路的数据包传输速度,但是文章提出的使用网络加速器方法,可明显地降低ICT设备的能源消耗,其降低量是原来不使用网络加速器时的1/3。

Virtual computer is widely used in cloud computing,can cause the user to the server of the distance is longer than before,cause the performance degradation of virtual computer,this will lead to the deterioration of quality of service and ICT （Information Communication Technology） equipment energy consumption increase.According to this problem,this paper presents a network accelerator automatically applied to the method in the cloud computing network.In order to use the current mainstream network accelerator,scheme adopted based the data transmission on mSCTP.The protocol uses the transmission control protocol in different before and after the migration （TCP）connection.This article does not consider the dynamic migration itself can make a virtual computer performance degradation,The experimental results show that,although the need to install the network accelerator as part of cloud resources and increase the communication link for data packet transmission speed,the network accelerator method which is proposed in this paper can significantly reduce the energy consumption of ICT devices.Power consumption with network accelerator could be reduced to one-third of that without network accelerator.
