软件定义网络（SDN）允许使用可编程网络设备，包括交换机和路由器。与其他软件一样，SDN中的错误是不可避免的，并会破坏软件质量。为了确保高质量的SDN软件，SDN环境中的可编程设备和组件必须不断检查和改进。为了实现这一目标，市场上提供了以下SDN测试和调试工具：OFf，ndb，OFRewind，NICE，Flowernet，Veriflow，SOFT和OFTest。这些工具在本文中进行了调查，考虑他们的能力，优点和缺点。主要功能包括：检查流表的一致性、网络流量的回溯、检查交换机转发规则、记录和重放所有或选定的流量以及检测网络配置变化。
Software Defined Networking (SDN) enables the use of programmable networking devices including switches and routers. As with other software, bugs are inevitable in SDN and ruin software quality. To ensure good quality SDN software, programmable devices and components in a SDN environment must be continuously checked and improved. To achieve this, the following SDN testing and debugging tools are available in the market: OFf, ndb, OFRewind, NICE, FlowChecker, Veriflow, SOFT, and OFTest. These tools are surveyed in this paper by considering their capabilities, advantages, and disadvantages. The main capabilities are: checking consistency of flow tables, backtraces of network traffic, checking switch forwarding rules, recording and replaying of all or selected traffic, and detection of network configuration changes.
