GEANT2 operational services
Connect. Communicate. Collaborate
• Basic IP access via the GEANT2 router
• ‘GEANT+’ service: a point to point (P2P)
service typically of GE paths within a 10 GE
access
• Managed wavelength service: P2P service of
full rate 10 Gb wavelength

GÉANT2 P2P User Group 1:
Large Hadron Collider
Connect. Communicate. Collaborate
• Providing 10Gbps circuits on the primary Tier 0 to Tier 1
routes: 9 delivered so far
• Additional 1Gbps circuits provided on some Tier1-Tier1
routes
• IP backbone supports further international data transfers
GÉANT2 P2P User Group 2:
