Conclusions Connect. Communicate. Collaborate • Obviously Basel-Geneva is very busy – Some lambdas can be brought in to CERN via Lyon (but at additional cost) • Further investigations required in particular concerning: – – – Physical routing of Qwest USLHCNET lambda Physical routing of GRIDKA-IN 2 P 3 in Strasbourg/Kehl Street level routing of GRIDKA-SARA (& GEANT 2 fibre) near FFM airport Physical routing of SARA-NDGF (Hamburg-Copenhagen) Physical routing of COLT/VSNL USLHCNET lambda (VSNL N CLS-FFM) Physical routing of GRIDKA-IN 2 P 3 in Paris area • Firmer conclusions will be drawn after these have been resolved
