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

- 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

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

- Main tasks:- Maintain web site at http://www.glif.is/- Meeting support: Kevin Meynell & Peter Szegedi - Media support: Press releases and a brochure

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/- Newest GOLE: SouthernLight (São Paulo, Brazil)

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

2020

- 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 LightGLIF, 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)

GLIF, Linking the World with LightGLIF, 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

Ctrl plane: Onwards!

- Collectively working on an inter-domain GNI (GLIF’s 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

Work towards next meeting

- Progress the Task Groups

- Will work closely with OGF’s 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
