【 摘 要 】

The Steinbuch Centre for Computing (SCC) at Karlsruhe Institute of Technology (KIT) has been involved fairly early in 100GE network technology. Initiated by DFN1(the German NREN), a first 100GE wide area network testbed over a distance of approx. 450 km was deployed between the national research organizations KIT and FZ-Jülich in 2010. Three years later in 2013. KIT joined the Caltech SuperComputing 2013 (SC132) 100GE «show floor» initiative using the transatlantic ANA-100GE link to transfer LHC data from a storage at DE-KIT (GridKa) in Europe to hard disks at the show floor of SC13 in Denver (USA). The network infrastructure of KIT as well as of the German Tier-1 installation DE-KIT (GridKa). however. is still based on 10Gbps. As highlighted in the contribution «Status and Trends in Networking at LHC Tier1 Facilities» to CHEP 2012. proactive investment is required at the Tier-1 sites. Bandwidth requirements will grow beyond current capacity and the required upgrades are expected in 2015. In close cooperation with DFN. KIT drives the upgrade from 10GE to 100GE. The process is divided into several phases. due to upgrade costs and differing requirements in different parts of the network infrastructure. The requirements of the different phases as well as the planned topology will be described. Some of the obstacles we discovered during the deployment will be discussed and solutions or workarounds presented.
