软件定义交换（SDX）是一种新型的网络互连范例，它允许多个独立的管理域共享计算、存储和网络资源。虽然SDX这个术语是最近才出现的，但这个概念已经被许多不同的学科所使用。例如，云计算研究人员使用它将网络虚拟化资源添加到他们的云间，而网络研究人员使用它将SDN技术插入网络交换基础设施。尽管用途不同，但通过虚拟化以及控制和数据平面的分离，共享网络资源的各种学科的努力汇聚到一个单一的波因点。本文介绍了一个调查的最相关的SDX研究从不同的研究领域，专注于他们的架构。本文定义了SDX的分类，提供了通用的体系结构模型，并提出了一个定性分析的体系结构，重点是可扩展性，弹性，对等技术和部署的SDX。
A novel internetworking paradigm, software-defined exchange (SDX), allows multiple independent administrative domains to share computing, storage, and networking resources. Although the term SDX is very recent, the concept has already been used by many distinct disciplines. For example, cloud-computing researchers use it to add network virtualization resources to their inter-clouds, while networking researchers use it to insert SDN technologies into the networking exchange infrastructure. Despite the different uses, the efforts of the various disciplines that share networking resources converge to a single poing enabled by the virtualization and the separation of control and data planes. This paper presents a survey of the most relevant SDX studies from various research areas, focusing on their architectures. The paper defines a taxonomy for the SDX, provides generalized architecture models, and concludes by presenting a qualitative analysis of the architectures that focuses on the scalability, resilience, peering technologies, and deployment of SDX.
