SURFnet

- Dutch National Research & Education Network (NREN)

- Not for profit organization, 60 employees

- 100% ownership by users via SURFfoundation

- 180 connected institutions, 750.000 end-users

- Business-model:- Innovation by project subsidies (14 M€/year)- Operations by tariffs from institutions (18

M€/year)

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 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

LHC high-level network architecture

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.

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 Research10

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 Research11

SURFnet6 overview

- Nation-wide hybrid optical and packet switching infrastructure

- Based on 6000+ km of SURFnet-owned managed dark fiber, all the way to the institutions premises

- SURFnet6 delivers 1/10 Gbit/s IP services (native IPv4 and IPv6) plus lightpath provisioning:- Over a single transmission infrastructure- Managed via a single control plane- In an economically sound way

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.

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 Research16

GLIF Working Groups (1)

- Governance and Growth (GOV) Working GroupChair: Kees Neggers (SURFnet)Goals: To identify future goals in terms of lambdas,connections and applications support, and to decide whatcross-domain policies need to be put in place.

- Research and Applications (RAP) Working GroupChair: Maxine Brown (UIC) & Larry Smarr (UCSD) Goals: To train a new generation of scientists on the use of super-networks.

GLIF Working Groups (2)

- Technical Issues (Tech) Working GroupCo-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 GroupChair: 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.

GLIF resources: lambdas

SURFnet, Pioneering Network for Higher Education and Research19

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
