摘要
随着互联网持续发展,网路虚拟化技术不断应用于用户多样化需求的实现。基于软定义网络(Software-Defined Network,SDN)的数据控制分离和可编程特性,为网络虚拟化实现提供了先天优势。因此,基于软定义网络的网络虚拟化成为计算机网络的研究热点。立足当前基于SDN的虚拟化平台研究,首先概述SDN和网络虚拟化的相关技术,然后重点对主流的基于SDN的虚拟化平台的架构和工作原理进行解析,总结其各自的优点和不足,最后探讨其下一步的研究方向和趋势。
With sustained development of the Internet,network virtualization technology is continuously applied to realizing the users＇ diversified needs.SDNs（Soft-Defined Networks） have many advantages in network virtualization implementations for its data-control separation and programmable features,thus the SDN-based network virtualization is becomes a hotspot in computer network research.Based on current research of virtualization platform,first of all,the technologies of SDN and network virtualization are presented,then the architecture and working principle of the mainstream SDN-based virtualization platform analyzed,and their advantages and disadvantages also summarized.Finally,the next research directions and trends are discussed.
