4 GLIF, Linking the World with Light GLIF Vision Linking the World with Light -Optical networks are the central architectural element in support of this decades most demanding e-science applications -Hybrid networks are the next-generation networks with dedicated lightpaths for guaranteed high-speed few-to- few usage -Research: -Does not have any geographical boundaries -Needs an interoperable and inclusive approach -Needs world-wide collaboration and coordination

5 GLIF, Linking the World with Light The GLIF today -GLIF is all about collaboration, sharing of knowledge, experience and resources -GLIF is not a network/provider nor a standards body -The GLIF has participants, not members -Number of participants: 49 -Additions in April: CPqD en RNP (both from Brazil) -Participants meet twice a year -Work done in smaller groups and on mailing lists

6 GLIF, Linking the World with Light GLIF Secretariat -Run by TERENA Secretariat in Amsterdam -Number of sponsors: 23 -Main tasks: -Maintain web site at -Meeting support: Kevin Meynell & Peter Szegedi -Media support: Press releases and a brochure

19 GLIF, Linking the World with Light Last meetings -Last (interim) meetings of Tech and Ctrl co-located with TIP2008/APAN in Honolulu, HI, USA -45 participants from 5 continents -Some results: -Sharing of research results: -Multi-layer path finding -Indepth discussions on: -VLANs for Lightpaths -Dynamic Lightpaths and GOLEs -GOLE Teleconferences -Task Groups formed -Merge Tech and Ctrl into one

20 GLIF, Linking the World with Light Tech Task Groups -GOLE Service Level Specification: -Walter van Dijk (SURFnet), Christian Todorov, Jim Williams, Geoff Lakeman -Global Lightpath ID: -Ronald van der Pol (SARA), Thomas Tam, Lars Fischer, Tom Lehman -PerfSONAR Lightpath Monitoring Demo: -Thomas Tam (CANARIE), Ronald van der Pol, Lars Fischer, Dongkyun Kim, Jeff Boote

21 GLIF, Linking the World with Light Ctrl Task Groups -Generic Network Interface -Security and Authorization -Failure Modes -Topology Exchange (on what is shared to who)

22 Lightpath contracting & fault resolution processes parallel "master contractor" process serial "peering relationship" process

GLIF, Linking the World with Light -Many Network Resources (globally) -NRENs - Internet2, NLR, CANARIE, HEAnet, GRnet,... -Coordinating Networks - ESnet, GLORIAD, GÉANT2, NORDUnet,... -Testbeds - Dragon, G-lambda, Phosphorus, Viola,... -GLIF Resources - NetherLight, GLORIAD,... -Campus Networks - not much work yet -Each has own control mechanisms Challenges for Global interoperability (1)

GLIF, Linking the World with Light -Heterogeneous technologies: -Ethernet (WAN and LAN), and PBB-TE -SDH, SONET -DWDM -Layer 2 MPLS -Heterogeneous Control Mechanisms: -Management plane (TL1, SNMP, proprietary,...) -Control Plane (GMPLS, MPLS, etc.) -WEB XML, REST, WSRF, SOAP, web services,... Challenges for Global interoperability (2)

GLIF, Linking the World with Light What is needed as a first step is … -Agree to a high level architecture with loose agreement on functional components … NOT implementation -A standard API to create interdomain lightpath(s), agreed upon by the community -Developed and supported by the community -Work closely with OGF (NML) and others for standardization

GLIF, Linking the World with Light Working Interfaces -CANARIE - UCLP -ESnet - OSCARS -G-LAMBDA - GNS-WSI -HPDM - VLAN based lightpaths -NORTEL - DRAC -UvA – Network Description Language -Phosphorous - G2MPLS, UCLP2, NRPS - > NSP -GN2/JRA3 - AutoBAHN & IDM -Internet2 - DRAGON/HOPI & DCN -FermiLab - Lambda Station -DoE - LambdaStation, TeraPaths

27 GLIF, Linking the World with Light Outline -GLIF Overview -GLIF Tech and Ctrl -Next steps

28 GLIF, Linking the World with Light Ctrl plane: Onwards! -Collectively working on an inter-domain GNI (GLIFs Generic Network Interface) task group -Existing WSDL as starting point -Use existing interfaces to capture the minimum set of calls and parameters, agreeable and to be ratified by all

29 GLIF, Linking the World with Light Work towards next meeting -Progress the Task Groups -Will work closely with OGFs GHPN and NMLwg for standardization -Communicate to IAB and a couple of area directors from IESG/IETF about our work on if/how it fits

30 GLIF, Linking the World with Light Next meeting -8th Annual Global LambdaGrid Workshop: -October 1-2, Seattle, WA, USA
