A 100 Gigabit Testbed was established in a collaboration of 6 partners. Three industry partners have contributed the fiber infrastructure, the DWDM equipment, as well as the required routers. 447 kilometer was the distance of the wide area testbed established in collaboration with the German NREN DFN between Karlsruhe Institute of Technology and Forschungszentrum Jülich. Before starting, DFN assured the quality of the fiber infrastructure, the operation of the DWDM systems at both locations, as well as the connection of the routers to this WAN link with a bandwidth of 100GE. 12*10GE interfaces were available at each site for connecting the local testnodes to the routers. A monitoring and measurement framework was installed for recording the most important IP network performance metrics, among them the One Way Delay (OWD) and its Variation, Packet Loss and Packet Reordering. The delay measurements were conducted between the GPS time synchronized Hades [1
