  3. Optical Internetworking Forum (OIF)Overview • Launched in April 1998 with the main objective to foster the development of low-cost and scalable internet using optical technologies • The only industry group bringing together professionals from the data and optical communities • Open forum: 130+ member companies • Carriers • Component and systems vendors • Testing and software companies • OIF MissionTo foster the development and deployment of interoperable products and services for data switching and routing using optical networking technologies • www.oiforum.com

  4. Architecture and Signaling Carrier Interoperability OAM&P Physical Layer User Group Physical and Link Layer Optical Internetworking Forum (OIF)Organization and main focus

  6. Optical Internetworking Forum (OIF)Outputs • Implementation agreements, using • Carrier & user group’s requirements • Existing standards and specifications when available • Newly developed solutions when necessary • Interoperability demonstrations, to validate industry acceptance and maturity of implementation agreements • Testing methods, to evaluate interoperability that will help in the accelerated development of interoperable products and networks • Inputs to other standardization bodies and fora

  8. OIF World Interoperability Demo 2004 (I) • Interop Area 1: Fast, automatic and dynamic end-to-end optical multi-vendor connection management • Demo objectives • Dynamic resource allocation by a standardized control plane • Automatic provisioning by client equipment via UNI interface (Switched connections) or by management system (Soft permanent connections) • Automatic multi-domain provisioning via E-NNI interface • Carrier perspectives and benefits • Enabling of advanced, customizable services • Enabling of multi-vendor interoperability • Simplification of node/network management • Effort and time reductionfor end-to-end service provisioning

  9. OIF World Interoperability Demo 2004 (II) • Interop Area 2: Efficient Ethernet transport over SONET/SDH (GFP, VCAT, LCAS) • Demo objectives • Generic Framing Protocol: mapping Ethernet over SONET/SDH • Virtual Concatenation:flexible bandwidth allocation and diverse paths • Link Capacity Adjustment Scheme: hitless bandwidth modification • Carrier perspective and benefits • Efficient use of existing SDH infrastructure for offering Ethernet data services • Possibility of advanced Ethernet connectivity • Packet data with SONET/SDH grade reliability and multiple QoS

  19. Significance of the Achievement • First time ever in the industry to conduct world wide multi-carrier interoperability testing • Carrier’s close involvement and strong support is a key milestone towards deployment of automatically switched optical networks • Lays the foundation for future testing methodology and demo infrastructure • Successful control plane and data plane integration and interworking • validates OIF’s Implementation Agreements and ITUs Standards • demonstrates that standardization clearly facilitates multi-vendor, world-wide interoperability • Successful validation of multi vendor interoperability on Ethernet service adaptation (GFP, VCAT/LCAS) • Demonstrates the possibility to offer new services over legacy network in a cost-effective way

  20. Conclusions • Large scale, world wide OIF interoperability testing is progressively validating the maturity of NG-SDH and IP over Optical technologies • The strong presence of Carriers and Vendors in OIF ensures proper setting of requirements for next generation IP/optical networks with advanced control plane • The valuable effort of Carriers and Vendors in OIF is accelerating the development of easy-to-deploy solutions • Further cooperative effort is needed by all Standardization Bodies to make available completely standardized solutions
