GÉANT2 Topology

The GEANT2 network, shown below, connects 34 countries through 30 national research and education networks (NRENs).

Network design for GÉANT2 has focused on maximising operational and service flexibility. Handling the development of traffic patterns is crucial to the success of the network. The network architecture makes use of a flexible structure based on a combination of routed IP and switched components.

The roll-out of the GÉANT2 network is almost complete:

• All of the network's 25 Points of Presence (PoPs) are fully equipped and in service.
• 43 of the network's total of 44 routes are fully installed and operational, with just one of the 18 dark fibre routes still in preparation.
• The first links came into service in early December 2005, between Switzerland and Italy, and Switzerland and Germany, respectively.

Multiple 10Gbps wavelengths are being employed in the network's core.
