The LSDF uses a 10 Gigabit Ethernet (10GE) throughout its infrastructure maintained by the networking department of SCC. The SCC NET department combines highest standards in operational stability with continuous improvements of the network software and infrastructure fixtures.

Striving to have as much services as possible the network has been designed to be as redundant as possible by double connections and highly available routers using double supervisor boards. However redundancy is sometimes limited by hard and or software capabilities. Some connections are shared with the KIT backbone as long as the network traffic does not affect each other significantly.

Networking engineers Ms. Aurélie Reymund, Ms. Elena Huck and head of the SCC/NET Mr. Reinhard Strebler have designed a state of the art low latency, campus wide, top speed data shipping highway to serve data intensive science at KIT. A detailed drawing of the logical and physical network layout, courtesy SCC/NET, can be downloaded as pdf by clicking on the thumb below.
