The OFELIA TUB-island an Europe-wide connected OpenFlow testbed

This paper introduces the OpenFlow testbed at the Technical University of Berlin, which was created in scope of the European project OFELIA. It briefly explains the need for future internet testbeds and gives a detailed overview about the entire hard- and software architecture. The concept for providing testbed resources to internal and external researchers as well as how to execute experiments will be explained. Actually, some experimental examples and results will show what can be achieved from the experimenter's perspective. This testbed uses common OpenFlow networking equipment and delivers measurement samples with real world results for software defined networking environments because under laboratory conditions tested flow processing algorithms can be evaluated on a real network infrastructure.
