| Popis: | 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 Julich 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]measurement nodes at each location. Additionally all relevant counters at the routers have been recorded using a SNMP based Network Manangement Station and supplemented special command line interface output gathering and parsing scripts. The interfaces statistics were stored in 60 second intervals. The aim of the testbed was to demonstrate a failure-free transmission of one or more IP datastreams over 100GE during the whole period of 4 weeks.This included the evaluation of the 100 Gbit/s optical transmission system, the 100GE interfaces between the routers and the optical system, and the evaluation of a sustained 100GE transmission as well as the evaluation of the use of 100GE in a production like environment. The evaluation included a circulated (in a routing loop) tunable load between 1 and 100 Gbit/s, measurement of transmission quality of TCP and UDP datastreams between the endsystems, measurements of one way latency, a ramping up data transmission from approx. 8 Gbit/s up to 96 Gbit/s. |
