1. Erik-Jan Bos GLIF Tech co-chair GLIF, the Global Lambda Integrated Facility CCIRN meeting Xian, China August 26, 2007 GLIF Tech (and other WGs)

2. 2 GLIF vision Linking the World with Light 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 decades most demanding e-science applications.

3. 3 GLIF Tech and Ctrl Working Groups GLIF Tech: Facilitate manual use of the GLIF resources today GLIF Ctrl: Towards automated use of the GLIF resources tomorrow

4. 4 A whos who in the Working Groups Governance and Growth (GOV) Working Group Chair: Kees Neggers (SURFnet) Goals: 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 (RAP) Working Group Chair: Maxine Brown (UIC) & Larry Smarr (UCSD) Goals: To train a new generation of scientists on the use of super-networks. Technical Issues (Tech) Working Group Co-Chairs: Erik-Jan Bos (SURFnet) & René Hatem (CANARIE) Goals: The goals of the working group are to design and implement an international LambdaGrid infrastructure, identify which equipment is being used, what connection requirements are required, and which functions and services should be provided. Control Plane and Grid Integration Middleware Working Group Chair: Gigi Karmous-Edwards (MCNC) Goals: To agree on the interfaces and protocols that talk to each other on the control planes of the contributed Lambda resources. People working in this field already meet regularly in conjunction with other projects, notably the NSF-funded OptIPuter and MCNC Controlplane initiatives.
