软件定义网络（SDN）已经成为一种流行的技术，被采用在业务网络中，并成为一个热门的研究课题。如今，许多网络测试平台都用于测试新的研究解决方案，并将受益于为其用户提供SDN实验功能。然而，将SDN暴露给实验者是具有挑战性的，因为实验必须彼此隔离，并且必须公平地共享有限的交换机资源。我们概述了三种不同的方法，将SDN暴露给实验者，同时实现隔离和公平共享的目标。这些解决方案使用软件实现、共享硬件交换机和智能网络接口卡在测试床中实现SDN。这些方法正在两个可运行的SDN测试平台上开发：南加州大学/ISI/伯克利分校的DeterLab和新加坡国立大学的NCL测试平台。
Software-defined networking (SDN) has become a popular technology, being adopted in operational networks and being a hot research topic. Many network testbeds today are used to test new research solutions and would benefit from offering SDN experimentation capabilities to their users. Yet, exposing SDN to experimenters is challenging because experiments must be isolated from each other and limited switch resources must be shared fairly. We outline three different approaches for exposing SDN to experimenters while achieving isolation and fair sharing goals. These solutions use software implementation, shared hardware switches and smart network interface cards to implement SDN in testbeds. These approaches are under development on two operational SDN testbeds: the DeterLab at USC/ISI/Berkeley and the NCL testbed at the National University of Singapore.
