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 decade’s most demanding e-science applications.

A who’s who in the Working GroupsA who’s who in the Working GroupsA who’s who in the Working GroupsA who’s who in the Working Groups

• Governance and Growth (GOV) Working GroupChair: 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 GroupChair: Maxine Brown (UIC) & Larry Smarr (UCSD) Goals: To train a new generation of scientists on the use of super-networks.

• Technical Issues (Tech) Working GroupCo-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 GroupChair: 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.
