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

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

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

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)
15

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.

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.

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
