GN4-1 Research and Education Networking - GÉANT

Periodic Reporting for period 1 - GN4-1 (GN4-1 Research and Education Networking - GÉANT)

Reporting period: 2015-05-01 to 2016-08-31

The challenge we face is to provide an open space for knowledge, innovation and growth by providing the best possible digital infrastructure to serve all users, from flagship big science to citizen research.

GÉANT, the pan-European communications infrastructure serving Europe’s research and education (R&E) community, delivers advanced multi-domain services and facilitates joint-research activity that drives innovation. Together with Europe’s National Research and Education Networks (NRENs), the GÉANT network reaches over 50 million users in 10,000 institutions.

The GN4 Phase 1 (GN4-1) project was the first step in implementing the actions defined in the 68-month Framework Partnership Agreement established between the GÉANT Consortium and the European Commission. At the same time, the project also maintained, operated and enhanced a set of high-performance production networking services.

The overall objective of GN4-1 was to provide a stable, though innovative, environment for the growth of GÉANT as the European Communications Commons for the European Research Area (ERA), providing the best possible digital infrastructure to ensure that Europe remains at the forefront of research. GÉANT achieved this through network evolution and cost-optimisation, development of a portfolio of key services, engaging with industry leaders, working closely with the other e-infrastructures and welcoming new user communities.

The work in GN4-1 developed new capabilities and evolved and evaluated emerging technologies in collaboration with partners and industry in support of some of the most demanding network-based applications. Thanks to the terabit network, 50 million researchers, scientists, academics and students can now share record volumes of data unconstrained by geographical location. These collaborations are helping to solve some of mankind’s biggest challenges, including sustainable energy, deep space, high-energy physics, earth observation, environmental disasters, medicine and more.
A key element in the achievement of this objective was to maintain the operational excellence of the established GÉANT services, while achieving significant economies on the costs of the backbone network (€3.2M cost savings were achieved).

The implementation of GÉANT as the European Communications Commons for the European Research Area (ERA) continues to provide the best possible digital infrastructure to maintain a leading role in research. GÉANT’s extensive and long-standing contacts with large data disciplines such as biology, radioastronomy and high-energy physics help shape the evolution of state of the art networking facilities. This is complemented by partner contacts with research domains that are new users of high-performance networks and services, such as: digital preservation, real-time art and humanities and new collaborations with e-infrastructures.
In addition to the individual work package objectives, GN4-1 also:
• Maintained and enhanced the production service and achieved cost reductions without a negative impact on network service levels.
• Coordinated with the other European e-infrastructure efforts (e.g. PRACE, EUDAT, EGI, OpenAire) both individually and in the framework of the increased coordination effort planned by the EC.
• Provided a global extension of existing partnerships with CERN/LHC, EUMETSAT, iMinds and InfiniCortex.
• Expanded the footprint and increased the depth of services offered to roaming users with enhanced trust and identity services (in coordination with the AARC project) through Federation as a Service, and with added group and attribute management in eduGAIN. This was achieved by:
○ Growing eduGAIN by 150% of the baseline number of participating entities.
○ Supporting attribute release in eduGAIN by supporting deployment of the Research and Scholarship Entity category (usage increased by more than 400%) and by the Code of Conduct (usage increased by 225%).
○ The transition of Federation as a Service to production.
○ Completion and approval of the Moonshot business case, service definition and pilot.
• Developed online, real-time services to improve the ease and function of videoconferencing, open learning support and general multimedia use.
• Reviewed the existing service catalogue using the Product Lifecycle Management (PLM) process to carefully assess the cost/benefits of each service, as well as to inform the strategy for future service development.

At the end of GN4-1, the GÉANT Service Catalogue included the following network, trust and identity and other application services:
• GÉANT IP: The standard connectivity service, providing robust, high-bandwidth access.
• GÉANT Plus: Point-to-point connectivity across reserved, high-speed circuits.
• GÉANT Lambda: Providing dedicated, full 10 and 100Gbps point-to-point connectivity.
• GÉANT L3VPN: An enhancement of the GÉANT IP service, which provides L3 virtual private networks.
• GÉANT Testbed Service: A production service facilitating network research in virtual environments.
• GÉANT Open: A service for NRENs, international partners and approved commercial organisations.
• GÉANT Peering: A service that allows direct peering between NRENs and international partners.
• eduroam: A global service that provides secure WiFi roaming connectivity for the R&E community.
• eduGAIN: Enables the trustworthy exchange of Identity information between the GÉANT partners.
• perfSONAR: A multi-domain monitoring toolkit for performance tuning and diagnostics.
• eduPKI: Provides Public Key Infrastructure (PKI) certificates for GÉANT network services.
• FaaS: A hosted infrastructure to enable smaller countries to offer a Single Sign-on service.
• Cloud Brokerage: Offers selected cloud services to the pan-European GÉANT community.
• Multi-Domain VPN (GÉANT MD-VPN): A service that supports traffic across multiple VPN services.

GN4-1 comprised four Network Activities, three Joint Research Activities and eight Service Activities. In order to increase transparency and efficiency of Service Activities, increased focus was placed on operational services and the development of new services, such as Firewall on Demand (FoD) and integration of network services such as: Network to the Labs (NTTL), L2VPN Multipoint, Ethernet VPN (EVPN).

The Networking Activities enabled project cooperation and facilitated connection between partners, an ever-expanding user community, important stakeholder groups and many international relations, both on a technical (e.g. for standards and development) and operational levels, with international networks being developed jointly with institutions from other continents.

The Joint Research Activities acted as pathfinders for the relevant service and development activities.

In summary, GN4-1 provided the best possible digital infrastructure to ensure that Europe remains in the forefront of research and other knowledge endeavours. It cultivated a stable, though innovative, environment to operate, maintain and enhance a set of excellent production networking and other services. This ensured value and cost savings on the operational backbone and drove the take up of added-value services.

• Improvements to the cost effectiveness of the basic backbone network with faster network speed.
• Convenience and comfort of user access to other e-infrastructure services (databases, clouds, computing facilities, archiving, etc.) developed in collaboration with other e-infrastructure projects and users. To this effect, a senior coordinator was nominated (in 4/NA4) to work out concrete proposals to offer convenient and ubiquitous access to these services.
The GÉANT infrastructure is at the forefront of state-of-the-art research networking, and provides access to its infrastructure to the NRENs and through them to reach more than 50 million research and education users. The engineering principles are based on the highest capacity in optical fibres and on advanced multi-domain services, including authentication and authorisation. The infrastructure is capable of providing high-quality services, and at the same time hosting innovative research. The core backbone is capable of multiple 100Gbps over each fibre link, and Terabit connectivity can be achieved by a single node. The technical achievements are complemented by advanced service development, constant effort for reducing the digital divide and worldwide collaboration and coordination activities. The GÉANT network peers with similar infrastructure at the continent level, such as Internet2 and ESnet in the USA, providing a seamless service to users, worldwide.

The work in GN4-1 progressed beyond state-of-the-art hosting activities in key areas:
• Networking: Terabit networking, software-defined networking and network function virtualisation.
• Trust and Identities: eduroam and eduGAIN, development of Identity providing roles and technologies.
• Cloud: Cloud services and Cloud interoperability.
• Testbeds as a Service: to support innovative research in networking and services on an agile platform, federated with similar initiatives, worldwide (e.g. GENI, FIRE+).
