云计算背景下VXLAN技术的应用

Application of VXLAN technology in the background of cloud computing

在云计算的背景下,服务器的虚拟化对传统网络的数据迁移能力提出了非常高的要求。文章分析了当前非常典型的一种网络虚拟化技术—VXLAN技术,通过在三层IP网络之上建立基于数据链路层的逻辑隧道,使数据链路层数据能够穿越网络层的承载网络进行传递,实现虚拟机跨三层网络的动态迁移,有效地提高了数据的传输效率以及对硬件资源的利用率。

In the background of cloud computing, server virtualization puts forward very high requirements for data migration ability of traditional networks. As a very typical network virtualization technology at present, VXLAN technology allows data link layer data to pass through the carrying network of the network layer by establishing a logical tunnel based on the data link layer on the three-layer IP network. Thus, the dynamic migration of virtual machine across the three-layer network is realized, which effectively improves the data transmission efficiency and the utilization of hardware resources.
