摘要
随着云计算平台的高速发展,传统的网络架构已经不能满足需求,基于SDN(软件定义网络)技术实现数据平面的集中控制已经成为当前网络技术的演进趋势。文章在简要介绍OpenFlow、OpenStack等技术的基础上,实现了OpenFlow交换机的设计;同时,建立了一个基于OpenStack的IaaS云管理平台,进一步融合了SDN和云计算的优势,提出了一种在云计算平台下模拟SDN的方法。该方法能模拟实际的SDN,并利用模拟的网络评估网络性能,从而优化设计,降低SDN规划和建设的投入。
With the rapid development of cloud computing platform,the traditional network architecture can not meet our de-mands.The centralized control of data planes realized by the Software Defined Network (SDN)-based technology has become the evolution trend of the current network technologies.This paper first briefly introduces the design of the OpenFlow switch on the basis of such technologies as OpenFlow and OpenStack and the building of an OpenStack-based IaaS cloud management platform which further converges the advantages of SDN and cloud computing.Then,it presents a method of SDN simulation on the cloud computing platform,which can simulate the actual SDN and use the simulated network toevaluate the network performance,thus optimizing the design and reducing the input for SDN planning and construction.
