4. 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. 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. 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 http://www.glif.is/http://www.glif.is/ -Meeting support: Kevin Meynell & Peter Szegedi -Media support: Press releases and a brochure

8. 8 GLIF, Linking the World with Light GLIF Resources -Two categories: -GLIF Open Lightpath Exchanges (GOLEs) -Lambdas -GOLE: -Neutral and Open Exchange Point -Where lambdas connect to -Where Lightpaths get cross-connected -Number of registered GOLEs: 18 -Details on the GLIF Wiki at http://wiki.glif.is/http://wiki.glif.is/ -Newest GOLE: SouthernLight (São Paulo, Brazil)

9. 9 GLIF, Linking the World with Light New GLIF World Maps -Maps created by: -Maxine Brown (UIC/EVL) -Robert Patterson (UIUC/NCSA) -With input from the Community -Funding was provided by GLIF and the US National Science Foundation -Maps can be found at: -http://www.glif.is/publications/maps/ -Press release: -http://www.glif.is/publications/press/20080513.ph p

19. 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. 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. 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. 22 Lightpath contracting & fault resolution processes parallel "master contractor" process serial "peering relationship" process

23. 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)

24. 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 2.0 - XML, REST, WSRF, SOAP, web services,... Challenges for Global interoperability (2)

25. 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

26. 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. 27 GLIF, Linking the World with Light Outline -GLIF Overview -GLIF Tech and Ctrl -Next steps

28. 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. 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
