【 摘 要 】

The LHC Optical Private Network (LHCOPN), linking CERN and the Tier 1s, and the LHC Open Network Environment (LHCONE) which links these to the Tier 2 community both successfully supported the data transfer needs of the LHC community during Run 1 and have now evolved to serve the networking requirements of the new computing models for Run 2. We present here the current status and the key changes, notably the delivered and planned bandwidth increases, the ongoing work to better address the needs of the Asia-Pacific region, developments to improve redundancy and progress made for provisioning point-to-point links.
