1. An OIF Overview ITU All Star Network Access workshop June 2004, Geneva John McDonough V.P. OIF

2. Launched in April of 1998 with an objective to foster development of low-cost and scaleable internet using optical technologies The only industry group bringing together professionals from the data and optical worlds Open forum: 170+ member companies International Carriers Component and systems vendors Testing and software companies Our Mission To foster the development and deployment of interoperable products and services for data switching and routing using optical networking technologies OIF Overview

3. OIF Focus Low-cost Scaleable Optical Internetworking IP-Over-Switched Optical Network Architecture Physical layer Low-cost optical interfaces between networking elements Standard device level electrical interfaces for low-cost systems Control layer interoperability between data and optical layers Dynamic configuration using IP signaling and control mechanisms Accommodate legacy network under the new physical and control layer mechanisms

4. Output from OIF Develop implementation agreements using Carrier groups requirements as input Existing standards and specifications when available Developing new when necessary Develop interoperability testing procedure to ensure compliance and ultimately interoperable products and networks Provide input into other standards bodies
