Connect. Communicate. CollaborateGEANT2 operational services
• 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
• 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
