The MD-VPN service also provides privacy amongst different instances (VPNs) of the service i.e. the content being sent back and forth between the different sites is kept in the private entity that owns the data. This is achieved because the data flows of the MD-VPN customer are isolated from any other traffic, standard IP traffic and traffic of other the MD-VPN customers.
Use Cases for GÉANT MD-VPN
There is a wide scope for GÉANT MD-VPN use, from the long-term infrastructure with intensive network usage to quick point-to-point services for a conference demonstration. The following cases give examples of how GÉANT MD-VPN can be used to support R&E collaboration;
International Collaboration - Universities, labs and all scientific projects based on international collaboration will benefit from the use of GÉANT MD-VPN services as the end-to-end service demarcation and the ability to support "out of area" connections improve ease of use. LHCONE, ITER and CONFINE are examples of success. Future Internet projects are also target users for GÉANT MD-VPN using proxy services to provide outreach. Ad hoc P2P connections - For example conference demonstrations or P2P data transport between sites needed only rarely and only for short periods of time. The rapid deployment of VPNs will enable such projects to take advantage of the service whereas the time for deployment of earlier services would have been prohibitive. Distributed Infrastructure Services - Cloud service providers, Grid and HPC centres could offer services across VPNs to increase service assurance and to separate traffic flows for management and (possibly) billing purposes Scientific Infrastructure – GÉANT MD-VPN is ideally suited to hub and spoke network structures enabling access to centralised infrastructure projects. Also distributed networking for remote sensors could benefit from higher levels of assurance offered by VPNs Education – Ad hoc and semi-permanent VPNs can provide linkages between school and campus networks in a clearly separated manner. This can be used to support outreach projects and collaboration. Transparent Transport Services - As GÉANT MD-VPN can provide a transparent data transport, it can be used by high level network services like SDN, BoD and in general by future internet projects.
