Description
Besides a brief overview of the GridKa private and public LAN network, the
integration into the LHC-OPN network as well as the links to the T2 sites will be
presented in the view of the physical network layout as well as there higher
protocol layer implementations. Results about the feasibility discussion of
dynamical routes for all connections of FZK including all different types the LHC
Network concerning links (LightPath, MPLS tunnels, routed IP) will be part of the
presentation. A evaluation will show the quality and quantity of the current 10GE
link from GridKa to CERN traversing a multi NREN backbone structure via a MPLS
tunnel. The evaluation will be contrasted by results of first tests via the LHC-OPN
point to point Lightpath GridKa - CERN. The equipment of the first 10GE test setup
are based on IBM/Intel HW at GridKa and HP/Chelsio at CERN. The second testbed is
more or less symmetrical, on both sites 64bit HP Itanium nodes with Chelsio 10GE
NICs. It will be demonstrated a study of the ability of the nodes at Gridka
revealing there limitations and the benefit of TOE will be discussed.
