Running lifecycle experiments over SDN-enabled OF@TEIN testbed

Managing the lifecycle of service-realization experiments in Future Internet testbed environments is very challenging due to the unbounded scope of user-driven experiments. The lifecycle of experiments should be carefully designed and managed among users and operators so that tasks and responsibilities are well-defined for all experiment stages. The states of involved resources should also be appropriately managed to streamline the experiment lifecycle. In this paper, by considering these issues, we discuss the realization of lifecycle experiments over SDN (Software-Defined Networking)-enabled OF@TEIN (OpenFlow @ Trans-Eurasian Information Network). In order to partially automate the lifecycle experiments, we are working on the automated resource provisioning and experiment execution. To illustrate current progress, we demonstrate prototype lifecycle experiments that attempt to link bandwidth measurements and the automated re-installation and reconfiguration of broken resource node(s).
