Rene.Hatem@CANARIE.ca Chief Engineer GLIF-Tech WG co-chair GLIF OverviewThe Quilt Peering WorkshopSt. Louis MI, 12 October 2006
Talk outline • what is GLIF? • who is GLIF? • GLIF work • GLIF open exchanges / GOLES
Regional Yesterday’s hierarchical IP network Other national networks National or Pan-National IP Network Regional A Regional C Regional B Regional D University
Regional Trend in meeting networking needs of R&E and business: private networks, layer1 transit, cross-border fibre, etc. World World National DWDM Network World Child Lightpaths Regional B Regional A Regional C Regional D Child Lightpaths University Server
Creation of specialty IP networks, e.g. UBC Campus DWDM Tier 2 University Global Physics Network 1G Tier 1 CERN 5G Internet TRIUMF 1G BCnet 1G Main campus Network Health Network Border Router Firewall 1G 3G 3D HDTV to McGill Research Hospital Engineering Telecom
what is GLIF? • is an acronym • Global Lambda Integrated Facility • is a vision • whereby interconnected network resources, from contributing autonomous R&E optical domains, seamlessly support global-scale end-end LightPaths for research and education applications • is a laboratory • for application and middleware development on emerging optical lambda grids • is an international virtual organisation • to promote and support optical networking; established in August 2003 at 3rd Lambda Grid Workshop in Reykjavik
who are the GLIF participants? • no members; only participants • GLIF participants are organizations which share the vision • GLIF participants voluntarily contribute network resources and/or actively partake in GLIF activites • TERENA provides secretariat functions • to name a few participants: • Internet2, MAX, MCNC, NLR, PNWGP, StarLight, SURA • go to http://www.glif.is/participants/ for an *incomplete* list
what is the GLIF doing? • providing a platform for global cooperation of national/regional research and education networks, institutions and consortia working with lambdas • providing a forum for making contacts, exchanging information and experiences, and resolving technical problems • working towards harmonisation of services and policies, of LightPath contracting and fault management processes
how does GLIF work progress? • working groups: • Governance & Growth WG • chaired by Kees Neggers (SURFnet) • Technical Issues WG • co-chaired by Erik-Jan Bos(SURFnet) & René Hatem (CANARIE) • Control Plane & Grid Integration Middleware WG • chaired by GigiKarmous-Edwards (MCNC) • working closely with Open Grid Forum's Grid High Performance Networking RG • Research & Applications WG • co-chaired by Maxine Brown (UIC) & Larry Smarr(UCSD)
GLIF-Tech WG activities • document GLIF network resources • document NOC contact information • GOLE monthly coordination calls: • idea taken from I2 MAN LAN and SURFnet NetherLight • Chair chosen on 3-month rotation basis • Discuss GOLE adds/moves/changes • coordinate demo support for big events • document end-end LightPath contracting and LightPath troubleshooting processes • work on providing layer 1 diagnostics to NOCs and to researchers/applications • not a standards body
some GLIF terminology • not perfect – just "good enough" • GLIF network resources: lambdas and GOLEs • lambda: high capacity optical circuit terminating on a GOLE • LightPath [service]: a high capacity circuit or QoS-supported virtual circuit [service], or the concatenation of a string of such circuits forming an end-end LightPath. A LightPath can take up all or only a portion of the capacity of a lambda. • GOLE: GLIF Open Lightpath Exchange, comprised of one or more network devices performing LightPath switching
open exchange points • GLIF Open LightPath Exchange (GOLE) model • facilitate international interconnections • minimize quantity of colo, equipment and cards required • minimize call blocking probability at optical exchange points • can be a collection of equipment offering different exchange services • located in a carrier-neutral facility • CANARIE: GOLE Operator • in Chicago (StarLight), co-managed with StarLight • in Seattle, co-managed with PNWGP • User can call CANARIE, local partner, or use UCLP • CANARIE: GOLE User • CAnet 4 NYC-Amsterdam OC-192 terminates on Internet2 MAN LAN, and SURFnet NetherLight GOLEs
