Hybrid Networking What’s in GLIF for you?

1. Hybrid Networking What’s in GLIF for you? Erik-Jan Bos, SURFnet, The Netherlands

2. NREN Challenge • How to accommodate needs of scientific users for higher speed, higher quality networking, e.g.: • Astronomy: eVLBI and LOFAR • Particle Physics: Large Hadron Collider • Medical imaging & research • Media streaming, such as HDTV and 4K • While protecting the performance of the network for current users • And keeping the successful end-to-end model of the internet SURFnet, Pioneering Network for Higher Education and Research

5. We realized that… • Counting on bigger routers and fatter pipes was no longer a realistic option. • And introducing QoS was not a viable alternative of course. • Next Generation Research Networks would not be a simple extrapolation of the current Internet evolution anymore. SURFnet, Pioneering Network for Higher Education and Research

6. Hybrid networking • Hybrid Networking concept has evolved since 2001 in a global context, with yearly LambdaGrid Workshops. IP + lambdas • Packet switched internet for regular many-to-many usage • Light Paths for new high speed few-to-few usage SURFnet, Pioneering Network for Higher Education and Research

7. Lightpaths and OPNs • Lightpath: high quality and high capacity optical network connection • Lightpaths provide applications with dedicated bandwidth with fixed characteristics at relatively low costs and with added security • Optical Private Network: system of permanent lightpaths to interconnect multiple locations SURFnet, Pioneering Network for Higher Education and Research

8. GLIF, Global Lambda Integrated Facility • In 2003 it was agreed to continue the international cooperation for lambda networking under the name GLIF. • GLIF is an international virtual organization managed as a cooperative activity with ‘participants’ rather than ‘members’ under a lightweight governance structure. • Open to anybody sharing the vision of optical interconnection of different facilities, who voluntarily contributes network resources (e.g. equipment, lambdas) or actively participates in relevant activities. • Secretariat functions provided by TERENA with voluntary contributions from participants.

9. GLIF Vision Linking the World with Light • Optical networks are the central architectural element in support of this decade’s most demanding e-science applications. • A research world without geographical boundaries. • Hybrid research networks worldwide connected by lambdas and GLIF Open Lightpath Exchanges (GOLEs) SURFnet, Pioneering Network for Higher Education and Research

10. GLIF Working Groups (1) • Governance and Growth (GOV) Working Group Chair: Kees Neggers (SURFnet) Goals: To identify future goals in terms of lambdas, connections and applications support, and to decide what cross-domain policies need to be put in place. • Research and Applications (RAP) Working Group Chair: Maxine Brown (UIC) & Larry Smarr (UCSD) Goals: To train a new generation of scientists on the use of super-networks. SURFnet, Pioneering Network for Higher Education and Research

11. GLIF Working Groups (2) • Technical Issues (Tech) Working Group Co-Chairs: Erik-Jan Bos (SURFnet) & René Hatem (CANARIE)Goals: The goals of the working group are to design and implement an international LambdaGrid infrastructure, identify which equipment is being used, what connection requirements are required, and which functions and services should be provided. • Control Plane and Grid Integration Middleware Working Group Chair: Gigi Karmous-Edwards (MCNC)Goals: To agree on the interfaces and protocols that talk to each other on the control planes of the contributed Lambda resources.

12. GLIF Tech and Ctrl Working Groups • GLIF Tech: Facilitate manual use of the GLIF resources today • GLIF Ctrl: Towards automated use of the GLIF resources tomorrow SURFnet, Pioneering Network for Higher Education and Research

13. GLIF resources: lambdas SURFnet, Pioneering Network for Higher Education and Research

14. GLIF resources: GOLEs • GLIF lambdas are interconnected through established lightpath exchange points known as GOLEs: GLIF Open Lightpath Exchanges • GOLEs are comprised of equipment capable of terminating lambdas and performing lightpath switching, allowing end-to-end connections • GOLEs have an open connection policy SURFnet, Pioneering Network for Higher Education and Research
