IPv6 testing and deployment at Prague Tier 2

Abstract

IntroductionThe Tier2 Computing Center in Prague runs about 300 worker nodes and 100 storage and service nodes. Our site supports four big HEP experiments: ATLAS, ALICE, D0 and Pierre Auger Observatory. We have already exhausted our C-class IP range and we have to use NAT for several nodes which is not optimal from the performance point of view.Motivation for transition to IPv6
