2. What is the OIF?  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 communities  Open forum: 250+ member companies international carriers component and systems vendors testing and software companies  Mission: To foster the development and deployment of interoperable products and services for data switching and routing using optical networking technologies

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. OIF Structure Technical Committee: 6 Working Groups  Carrier Requirements and applications  Architecture Services, network requirements and architectures  Signaling Protocols for automatic management of optical connections  OAM&P (Operations, Administration, Maintenance and Provisioning) Network management  Physical and Link Layer Equipment and subsystem module interfaces  Interoperability Interoperability testing

5. Output from OIF  Implementation agreements, based upon: Carrier group’s requirements Existing standards and specification when available New solutions when necessary  Interoperability testing procedures Ensures compliance to implementation agreements and ultimately interoperable products and networks  Input into other standards bodies Formal liasons in place with numerous other organizations (e.g. ITU, IETF. Complete list in back-up slides)

6. OIF Process for Generating Implementation Agreements  Framework provided by Working Group structure Working groups establish consensus-driven projects to focus contributions  Progress driven by member contributions Posted on OIF website Basis for activities at quarterly technical meetings  Formal voting process for reaching Implementation Agreements Two step process Straw ballot – passes with simple majority Principal ballot – passes with 2/3 rd s majority Process enables open debate, incorporation of comments Formal votes at each step One vote per member company

7. OIF Activities – Physical Layer Business Need  Lower equipment costs through interface agreements that reduce customization Key Projects  Internal system interfaces System/Physical Interface (SPI) SPI-3, SPI-4 complete for 10G SPI-5 in progress for 40G Serializer/Deserializer-Framer Interface (SFI) SFI-4 complete for 10G SFI-5 in progress for 40G  Low cost premises equipment interfaces Very Short Reach (VSR) VSR-1, VSR-2, VSR-3, VSR-4 complete for 10 Gb/s VSR-5 in progress for 40 Gb/s Footprint specification for tunable lasers in progress Link Layer (Packet and Cell based Protocols) Rest of the System SONET/SDH Framer PHY Layer SERDES E/O Transceiver Transmission Media SPI SFI VSR

8. OIF Activities – Control Layer Switched Optical Networks  A switched optical network is an optical network in which connections can be created using switching control technology.  The OIF is among the organizations working on the interfaces to enable controllers to work together to perform this function Call Request Connection Request Call Accept Connection Indication

9. OIF Activities – Control Layer Optical Network B Client Business Need  Lower operations costs through automation of routing optical circuits Key Projects  User-to-Network Interface – enables client equipment to request a service across optical networks UNI 1.0 complete for SONET circuits  25 vendor interop. Demonstratation at Supercomm in June, 2001 Built upon protocols from IETF Also completed Call Detail Records to support billing with UNI 1.0 UNI 2.0 in progress to add other features  Network-to-Network Interface – enables optical networks to interact to deliver an end- to-end service NNI 1.0 in progress  Targeting 1H03 for interoperability demonstration Optical Network A Client NNI UNI

10. Why do service providers care about optical control plane interfaces?  Intelligent control plane, in general, lowers operating costs Automatic discovery of elements, capacity and connections Automatic routing and recovery of circuits Improved survivability against complex failures  “Standardized” control plane interfaces enable Wider adoption of control plane capabilities Multi-vendor/carrier interoperability New dynamic optical services with customer control “Plug and play” introduction of new vendors/technologies  In advance of control plane deployment, service providers will continue to rely on centralized management systems

11. OIF control plane work vs. other organizations  Internet Engineering Task Force (IETF) Community of individuals Generating “tool box” of protocols  International Telecommunications Union Formal organization for establishing global standards In progress of developing comprehensive standards for “Automatic Switched Optical Network”  Some overlap among OIF, IETF, ITU “Healthy” competition is evolving to cooperation Req’tsProtocols Req’tsFormals Standards Implementation Agreements

12. Summary  OIF brings together professionals from the data and optical worlds  OIF is addressing issues important to carriers and their customers  Control plane work is progressing well in OIF in collaboration with other organizations like the IETF and ITU
