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
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
