Abstract
OpenFlow is a recent standard that defines the interaction between a network element (switch, router) and an externalized control element (the controller). This article introduces the metrics of interest when developing hardware and software for OpenFlow and shows how these are made available in OFELIA, a Pan-European research testbed for software-defined networks. OFELIA provides software tools like OFLOPS and cbench as well as access to specific test hardware. A section of the article describes how this hardware is integrated into the control framework of OFELIA and how it can be used by external researchers. Some measurement results recently obtained with the use of OFELIA provide an example of experiments that are done to further optimize SDN equipment and controllers.
