GLIF vision
Linking the World with Light
• It is no longer sufficient to connect researchers to
the internet, they have to be connected to each
other.
• GLIF community shares a common vision of
building a new grid-computing paradigm, in which
the central architectural element is optical
networks, not computers, to support this decade’s
most demanding e-science applications.

A word on networking costs
• Costs of optical port is 10% of switching port is 10%
of router port with same characteristics
• 10G routerblade -> 100+ k$, 10G switch port >10k$,
MEMS port -> 1 k$
• Give each packet in the network the service it
needs, but no more

12
Paradigm shift
Hybrid networking
IP + lambdas
• Packet switched internet for regular many-to-many usage
• Light Paths for new high speed few-to-few usage
13
Light Path Provisioning
Lambdas:
• enable layer 1 and 2 end-to-end Light Paths
Light paths:
• provide excellent quality on point-to-point
connections at very high speed (1-10G)
• are not constrained by traditional framing, routing,
and transport protocols
• are becoming integral part of scientific instruments
• enable creation of Optical Private Networks (OPN)
14
Spring 2001 Start of lambda networking
• 2.5Gbit/s lambda ordered by SURFnet between
StarLight, Chicago, USA and NetherLight,
Amsterdam, NL
• Lambda terminated on Cisco ONS15454 muxes,
• WAN side: SONET framed: OC48c
• LAN side: GbE interfaces to computer clusters

History of Lambda Workshops
• Brainstorming in Antalya, TR at TERENA
Networking Conference in 2001
• Lambda workshops so far were by invitation only
but always attached to an open event related to
lambda networking:
• September 2001: first Lambda Workshop in
Amsterdam followed by open Lambda Workshop
organized by TERENA
16
GLIF History
• Second Lambda Workshop in 2002 in Amsterdam
was attached to iGrid2002, hosted by Science Park
Amsterdam
17
NetherLight Network 2002
• The iGrid2002 event brought many lambdas to Amsterdam
18
GLIF
• August 2003: third Lambda Workshop in Reykjavik
hosted by NORDUnet and attached to the
NORDUnet 2003 Conference
• In Reykjavik with 33 participants from Europe, Asia
and North America it was agreed to continue under
the name:
GLIF: Global Lambda Integrated Facility
19
GLIF Founding Members

GLIF after Reykjavik
• GLIF is a collaborative initiative among worldwide
NRENs, consortia and institutions with lambdas; as
such GLIF is clearly positioned on the demand side of
the market
• GLIF is a world-scale Lambda-based Laboratory to
facilitate application and middleware development
• GLIF will be managed as a cooperative activity
• WWW.GLIF.IS will be the home for all interested in the
GLIF activities
21
GLIF Working Groups
• Governance and Growth
• Kees Neggers - [email protected] - chair.
Goal: 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
• Peter Clarke - [email protected] - chair
Goal: To identify applications that can benefit from LambdaGrids, and to define the services
that the user communities need
• Technical Issues
• Erik-Jan Bos - erik-jan.bos @ surfnet.nl – co-chair
Rene Hatem - [email protected] - co-chair.
Goal: To design and implement an international LambdaGrid infrastructure, identifying
equipment, connection requirements, and engineering functions and services
• Control Plane and Grid Integration Middleware
• Gigi Karmous-Edwards - [email protected] - chair
Goal: To agree on the interfaces and protocols that talk to each other on the control planes of
the contributed Lambda resources
22
GLIF 4th Annual Workshop
• The GLIF 4th Annual Global LambdaGrid Workshop
was held in Nottingham, United Kingdom on
September 2 and 3, 2004 attached to the UK All
Hands eScience Meeting
Organized by Cees de Laat of
University of Amsterdam and
Maxine Brown of University of
Illinois at Chicago.

GLIF Nottingham Participants
24
GLIF after Nottingham
• GLIF is an open community
• GLIF has participants, not members
• GLIF “glues” together the networks and resources
of its participants
• TERENA to serve as the GLIF Secretariat
Appropriate to their mission and the spirit of
community cooperation, GLIF participants
implemented a “lightweight” governance structure.

Open GLIF Optical Exchanges
• GLIF infrastructure will be Multi-domain
• Like the Internet lambda networking will move from
research to commercial networks
Open GLIF Optical Exchanges will be key to facilitate
• the further evolution and scaling of the emerging
GLIF infrastructure.
• the interworking with the commercial domain
• the smooth migration from the research area to the
market
27
NetherLight: Open GLIF Optical Exchange
• Open Optical Exchange in Amsterdam
• Operational since January 2002
• Established in Science Park Amsterdam
• Built and operated by SURFnet
• Nortel Networks HDXc at the centre
with full duplex 640G non-blocking
cross-connect capability
• Nortel OME6500 and Cisco15454 at the
edge

Connectivity challenge
• Reaching out to the users
• So far most researchers have to come to the
emerging GLIF infrastructure
• Challenge is to bring GLIF to the desk top of the
researchers and to their scientific instruments
• This means bringing dark fiber to remote
instruments and hybrid networking functionality
into the LANs at the campuses
33
Middleware challenge
• How do we glue things together?
• Users need ubiquitous end to end lightpaths
connectivity over a multi-domain infrastructure
• Harmonize use of existing protocols
• Invent new protocols
• Create user friendly AAA features
• Paving the way to a ubiquitous and scalable
Services Grid
34
Application Challenge
• In the end its all about applications
• Stimulate the development of applications that
explore the new hybrid functionality
• Work closely with the GLIF users on best
practices to overcome the connectivity and
middleware challenges
• Explain the opportunities to other researchers

GLIF 5th Annual Workshop
The GLIF 5th Annual Global LambdaGrid Workshop will be held in
September 2005 in conjunction with iGrid 2005 meeting in the new
UCSD Cal-(IT)² building in San Diego, California, USA,
