Multi-national circuits are typically expensive, have long lead times for delivery and tie the user into lengthy service contracts. The GÉANT Plus service enables user access to point-to-point circuits of between 100Mbps and 10Gbps across an existing, pre-provisioned network that is quick to configure.
Although built on common infrastructure, GÉANT Plus looks like a dedicated service to users. This combines the privacy and availability advantages of a private circuit with the efficiency gains of a shared network.
Technical Description of the Service
Infrastructure
GÉANT Plus offers point-to-point Layer 2 connectivity across GÉANT IP interfaces. It is delivered over dedicated VLANs on the NREN interface.
The standard physical interface to access the GÉANT network can be either 10GE or 100GE. Currently, 100Gbps interfaces are only available for NRENs on GÉANT dark fibre.

Implementation
The GÉANT Plus service appears as a point-to-point connection which NRENs delivereall the way to their users at the NREN campuses.

In the GÉANT backbone, the service is supported by a full mesh of Labelled-Switched Paths (LSPs), ensuring resilience across the entire GÉANT footprint. This dynamic infrastructure allows for a self-healing service, where faults in the backbone are automatically handled by the underlying Interior Gateway Protocol (IGP).
Demarcation Points
The management demarcation point between DANTE and the NREN is a port on the Optical Distribution Frame (ODF) rack, as described in Figure 3, below.
The exact port will be specified at the time of the connection. The responsibility of the GÉANT Operations Centre (OC) ends at the declared demarcation point, patching beyond that point is the responsibility of the ordering NREN.

Circuits to Destinations Outside of Europe
The primary focus of the GÉANT Plus service is to offer European NRENs the ability to quickly and flexibly provision point-to-point connections. It is also possible to extend the network reach by connecting to non-European links. As GÉANT Plus leverages the IP infrastructure, an NREN connected to the GÉANT network can reach Internet2 and ESnet in the US, and Canarie in Canada.
Requests concerning non-European NRENs can be discussed on a case-by-case basis, as the remote end of the connection needs to be able to accept circuits. For further information please contact the GÉANT Partner Relations Team (partner-relations@geant.net).
Access to Bespoke Solutions
If the requirement for a point-to-point connection does not fit in the current description of the service, the GÉANT Partner Relations Team can be contacted to evaluate the feasibility of a bespoke implementation. Such implementation may incur extra cost.
