软件定义网络（SDN）的国际合作跨越了欧洲、美洲和亚洲的边界，为通过先进的可编程网络测试平台进行实验研究奠定了坚实的基础。欧盟-日本联合资助的项目FELIX（大规模基础设施实验的联邦化测试平台）考虑为分散在各大洲的联邦未来互联网（FI）测试平台定义一个通用框架。该框架将使实验者能够（i）动态地请求和获得不同测试床基础设施的资源;（ii）管理和控制连接联合SDN测试床基础设施的网络路径;（iii）监控底层资源;以及（iv）使用在联合基础设施上执行的分布式应用。本文详细介绍了将用于验证FELIX架构和软件平台的六个用例。我们提出了我们的分析和最终用户的考虑，强调有必要在测试平台网络的问题有一个全球视野。资源可达性和物理连接的一致使用是用例中的关键因素。这在考虑同时使用不同技术时尤其重要，例如OpenFlow和网络服务接口（NSI）等。
International cooperation on Software-Defined Networking (SDN), crossing the boundaries of Europe, the Americas and Asia, builds a strong foundation for pursuing experimental research through advanced programmable network testbeds. The EU-Japan jointly-funded project FELIX (FEderated Testbeds for Large-scale Infrastructure eXperiments) considers the definition of a common framework for federated Future Internet (FI) testbeds, which are dispersed across continents. This framework will enable an experimenter to (i) request and obtain resources across different testbed infrastructures dynamically; (ii) manage and control the network paths connecting the federated SDN testbed infrastructures; (iii) monitor the underlying resources; and (iv) use distributed applications executed on the federated infrastructures. This paper details six use cases that will be employed to validate the FELIX architecture and software platforms. We present our analysis and end-user considerations, highlighting the necessity to have a global vision of issues within the testbed network. Resource reachability and coherent use of physical connections are key factors in the use cases. This is particularly important when considering the simultaneous use of different technologies such as OpenFlow and the Network Service Interface (NSI) among others.
