摘要:

随着云计算的高速发展,虚拟化正成为近年来在企业级环境下广泛应用的技术。除服务器及存储虚拟化外,在SDN和OpenFlow技术的推动下,网络虚拟化成为热点,基于SDN的网络虚拟化平台也应运而生。在分析基于SDN的网络虚拟化设计目标的基础上,对近年来业界推出的4种典型SDN网络虚拟化平台的系统架构和原理进行了对比,并对其安全和隔离性进行了分析总结。

Abstract:

The rapid development of cloud computing has recently prompted extensive application of visualization in enterprise-level environments.In addition to server and storage virtualization,network virtualization attracts more and more attention with the application of SDN and OpenFlow.Therewith,software-defined network platforms designed for network virtualization were presented.Firstly,the objectives of the SDN based network virtualization platform were analyzed.Subsequently,the system architectures and principles of four typical network virtualization platforms based on SDN were compared.At last,the safety and isolation mechanism provided by the network virtualization platforms were investigated.
