Global Network Architecture for R&E Networks

Time 10/28/14 02:15PM-03:00PM

Room White River Ballroom B

Session Abstract

For over two decades, researchers and scientists in high-energy physics and radio astronomy have been working and collaborating on a global scale, using data networks. Many other research and science disciplines have been added to these examples over the last decade in fields as diverse as weather and climate research and microbiology and genome research. Education also is becoming a global endeavour with the fast rise of online education, MOOCs, and global campuses.

To accommodate the globalization of research, science, and education and to meet the needs of the user communities they serve, R&E Networks around the world have, over the past 20 years, been working to establish intercontinental connectivity. Over the years, this has matured from an individual “we all connect to the USA-based NSFnet backbone” private set of links to a more general-purpose R&E Network infrastructure.

When looking at maps like the APAN map, the GLIF map, the RedCLARA map, the map published by the GN3plus Project containing ORIENTplus, EuMedConnect, TEIN and others, it becomes apparent that there is a lot of R&E Network infrastructure out there today. Each of the links in this infrastructures serves a specific need, and –as expensive resources- are brought into the picture with well-argued reasons. Also, a substantial number of these links are limited in time, allowable usage, or both, as they are mission oriented or funded by money coming from a project with limited duration1. Very few of these links are brought into the picture with a coherent global architecture in mind, as coordination on a global scale has not been a priority until now.

The charge of the Global Network Architecture group from the NREN CEO Forum is to draft a blueprint for the intercontinental R&E Network interconnects, based on the latest technologies and promising developments, with a ten-year horizon. This blueprint will enable participating R&E Networks to align their spending for intercontinental bandwidth. The blueprint is all-inclusive, and has the potential to take along all regions of the world if and when they are ready to embark, bringing intercontinental network capacity as much as possible in line with what is available within the continents.

This talk will discuss the outcome from three sub-groups of GNA
1. Technology and Topology
2. Network Services
3. Operations and Security

And give overview of the services that will be supported on GNA and the proposed high-level GNA topology. The talk will also zoom into next steps and how the community can help define this future network architecture.
