These services as all services delivered by GÉANT will be not used by NRENs directly but delivered by the NRENs or the Regional Network (RN) to end-users. From the end-users point of view these services delivered are the same but from the NREN point of view these services are different in the way that GÉANT delivered them to the NREN and in the border of service. GÉANT plus and L3VPN deliver their service at the border of GÉANT whereas MD-VPN aims to provide the service at end user site (end-to-end service).

The other important difference is the features that are provided by different services.
