Networking Group

The group prepares plans and follows the implementation of the wide area networking needed to support the Computing Models of the LHC experiments both during the preparation and operation of the LHC. The group reports regularly to the Grid Deployment Board (GDB) on progress. The GDB approves the general strategy and plans developed by the group and agrees on a set of milestones to enable progress to be followed by the project and the experiments. The GDB chair will include relevant information on planning, progress and potential problems in his regular report to the PEB.

The network infrastructure interconnecting the centres providing computing resources for LHC will in most cases be provided by national and regional research network organisations, through agreements made between the computing centres and these organisations. The goal of the group is to ensure that these individual agreements will provide a coherent infrastructure to satisfy the LHC experiments' computing models and requirements, and that there is a credible solution for the management of the end-to-end network services.

The first priority of the group is to plan the networking for the Tier-0 and Tier-1 centres, based on the outcome of the LHCC Review of Experiment Computing Requirements scheduled for 17-19 January 2005, on a timescale compatible with the LCG Technical Design Report. The group should also cover Tier-2 centres, as appropriate information on requirements becomes available. The group is not concerned with networking for lower tiers.

The membership of the group includes networking experts from Tier-1 and other major regional centres, representatives of relevant research networking organisations, and other experts as agreed by the group.
