Enhancing Optical Networking Interoperability: Insights from OIF World Congress 2005

The Optical Internetworking Forum (OIF) provides insight into its mission of fostering optical networking development. Launched in April 1998, the OIF brings together over 130 member companies focusing on creating interoperable products and services. The 2005 World Congress in Paris highlighted key demonstrations, including dynamic end-to-end optical connections and Ethernet transport over SONET/SDH. The significant achievements in multi-carrier interoperability testing mark a pivotal step toward the future of automated optical networks, underscoring the importance of standardization in promoting industry-wide cooperation.

  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
