软件定义网络（sdn），主要基于OpenFlow，正在世界各地的单域网络中部署。SDN的普及带来了设计、实现和操作软件定义网络交换（sdx）的多重考虑，以使SDN能够互连SDN孤岛并跨多个域扩展SDN。这些目标只能通过开发新技术来实现，这些新技术可以扩展当前SDN/OpenFlow方法的单一域方向，以包括多域控制功能，包括资源发现、信令和动态供应。一些网络研究团体已经开始研究这些概念。sdx的早期架构模型是作为原型设计和实现的。这些sdx被用来进行实验和展示sdx的潜力。
Software Defined Networks (SDNs), primarily based on OpenFlow, are being deployed in single domain networks around the world. The popularity of SDNs has given rise to multiple considerations about designing, implementing, and operating Software-Defined Network Exchanges (SDXs), to enable SDNs to interconnect SDN islands and to extend SDNs across multiple domains. These goals can be accomplished only by developing new techniques that extend the single domain orientation of current SDN/OpenFlow approaches to include capabilities for multidomain control, including those for resource discovery, signaling, and dynamic provisioning. Several networking research communities have begun to investigate these concepts. Early architectural models of SDXs have been designed and implemented as prototypes. These SDXs are being used to conduct experiments and to demonstrate the potentials of SDXs.
