在本文中，我们介绍了 Vertigo（OpenFlow 网络中的虚拟拓扑通用化），这是一个专为网络虚拟化而设计的软件定义网络平台。 Vertigo平台基于OpenFlow原创网络切片系统Flow Visor，旨在覆盖所有类型的网络虚拟化：特别是能够在一端暴露一个简单的抽象节点，并在另一端提供逻辑上全连接的网络。在这项工作中，我们首先介绍 Vertigo 系统架构及其设计选择，然后报告部署在支持 OpenFlow 的测试台上的原型实现。实验结果表明，尽管底层物理网络出现故障和/或拥塞，Vertigo 仍可以为各种用例提供灵活可靠的网络虚拟化服务。
In this paper we present Vertigo (Virtual Topologies Generalization in OpenFlow networks), a Software-defined networking platform designed for network virtualization. Based on the OpenFlow original network slicing system Flow Visor, the Vertigo platform aims at covering all flavors of network virtualization: in particular, it is able to expose a simple abstract node on one extreme, and to deliver a logically fully connected network at the very opposite end. In this work, we first introduce the Vertigo system architecture and its design choices, then we report on a prototypical implementation deployed over an OpenFlow-enabled test bed. Experimental results show that Vertigo can deliver flexible and reliable network virtualization services to a wide range of use cases in spite of failure and/or congestion at the underlying physical network.
