  3. Overview of the GLIF Optical Exchanges Links in the GLIF The GLIF edge Usage of the GLIF Definition of a Light Path Connecting to the GLIF Using the GLIF Technical details of the GLIF GLIF building blocks Ethernet framing Protocol conversion 10GE LAN PHY and WAN PHY Available before summer ‘05 To be presented at iGrid2005 GLIF Best Current Practices document

  4. GLIF schedulable resources • Conclusion from Nottingham, UK Tech: • Maps are nice for overview, PR, etc. • For finding possible paths, we need the ability to drill down into the details • Work on services definition per GLIF participant • For further study: Semantic Web (Sir Tim Berners Lee, MIT)
