(Including candidate sites)
LHCOPN -‐‑KISTI’ GSDC LHC ALICE Tier1-‐‑
• GSDC/KISTI ~ CERN 2Gbps Network o Be upgraded 10Gbps at
the end of this year
• Backup Network o Direct peering between
KREONet2 and CERN at Chicago, 10Gbps (present)
o LHCONE L3VPN could be the secondary backup network of LHCOPN
• Getting transit over LHCOPN link for European CERN LHC Tier1

LHCONE Implementation of KREONET/GLORIAD-‐‑KR (plan) • LHC Open Network Environment • LHCONE Multipoint Service, VRF Instance
o LHCONE L3VPN Service
• Point-to-Point Service o Dynamic Circuit Networking Service with NSI o SDN/OpenFlow based transportation service : Multiple Stream
Transportation, Stream Aggregation,…
• Multi-Point Service o KREONET Dynamic Ethernet Service
• Allocating more than 1Gbps*n over GLORIAD circuit for LHCONE L3VPN (plan) o Daejeon, South Korea ~ Hong Kong, China o Daejeon, South Korea ~ Seattle, United States o Daejeon, South Korea ~ Chicago, United States
