Vision
The GÉANT3 programme creates an innovative, multi-domain hybrid networking infrastructure that enables R&E end-users and their organisations by providing flexible and scalable production-quality services via constituent NRENs.

GÉANT’s great achievement has been to provide quality services to a vast, demanding and diverse user base. Through its 32 constituent NRENs serving 4000 campus networks, GÉANT has a potential user base of more than 40,000,000 end-users, thereby forming the world’s largest and most advanced and diverse R&E networking system. Such a service can only be best managed using the current multi-domain hierarchy: Campus, NREN and Pan-European interconnect.

To progress even further, GÉANT3 must enable the scalable expansion of its user base, and offer diverse robust services within a confederated architectural model. GÉANT2 and the NRENs developed advanced hybrid switching infrastructures that are able to reach advanced R&E users and support e-Science initiatives. After the roll-out of these hybrid facilities, deployment of high-performance Virtual/Optical Private Networks (VPN/OPN) followed swiftly. These acted as a catalyst for the development of related end-to-end services. It is vital that the GÉANT3 community further develops robust multi-domain services in order to fulfil the requirements of the growing number of high-end R&E users.

To a great extent, the success of GÉANT2 has been due to the foresight of the NREN community, as shown by the SERENATE Reports and by the implementation and deployment of a hybrid dark fibre based inter-network. This implementation was a huge leap forward that exceeded predictions and placed GÉANT2 ahead of similar advanced initiatives worldwide. GÉANT3’s mission is to consolidate this innovation into a robust and stable operational multi-domain hybrid network, while at the same time contributing to future advances in network technology and developing state of the art advanced and robust services needed by the research and education communities throughout Europe and beyond.

It is envisaged that within the life time of GÉANT3, advances in core optical network technologies will be evolutionary rather than revolutionary. However, as well as advanced multi-domain systems, a multitude of user-driven virtual networks are being developed, and this trend may be considered as a revolutionary step forward. Therefore, GÉANT3 should evolve as a network “factory”, with the network itself being an entity capable of creating and/or hosting complex systems made up of circuits and nodes that enable community oriented services. However, there will also be a constant need to evaluate the significance of advanced technology without compromising the production quality of the GÉANT3 service portfolio.

Network infrastructures are becoming increasingly important because of the provision of advanced capabilities to end users through the network. Naturally, these high-performance end users will continue to exploit the opportunities that access to high speed networks brings (including growing Grid initiatives and other concepts encouraged by Cloud Computing). Architecturally, the general adoption of Service Oriented Architectures (SOA) will allow the integration of services from many different providers, thereby creating a vibrant and competitive set of offerings built on top of the network.

The NREN - GÉANT community, working together with peer non-European R&E initiatives, will be vital in realising the opportunities that the service oriented evolution will bring. In particular, GÉANT3 will provide innovative leadership in such areas as deploying network services as an integral part of the network infrastructure, meeting management challenges for federated networked applications, and influencing standards for reliable and efficient networking services.
