Core network, metro rings and city rings

The SURFnet network comprises of the core network, metro rings and city rings. As all of the connection points in the network are redundantly configured, the connections are extremely reliable.

Core network, metro rings and city rings

Institutions can be directly connected to one of the 21 locations in the core network. Connected to the core network are metro and city rings in which connections to the network can be created. 

Points of Presence redundantly configured

All the connection points (Points of Presence, PoPs) in the network are redundantly configured. This means that an institution is always physically connected to the network through two connections. If the main PoP fails, e.g. due to a fault or maintenance, the backup PoP will immediately take over the connection, thereby ensuring that the institutions do not experience any interruption in service.
