Major Accomplishments • Multi-layer call/connection control of UNI-N devices • Orchestrates actions between client and server layers • Controls Ethernet adaptation using GFP-F/VCAT/LCAS • Creation of end-end calls and connections across: • Multiple data plane layers • Multiple vendors’ equipment • Multiple carrier labs • The major features (1) Ethernet over SONET/SDH adaptation and (2) distributed optical control planes have each been demonstrated before • However, this is the first event bringing both together in an integrated fashion on a global scale
Interoperability: Carrier Benefits • Provision end-to-end dynamic connections for flexible data services over multiple, control plane enabled SDH/SONET domains • Deploy at faster pace innovative network technologies • Select cost effective and leading edge network elements, platforms and multi-vendor solutions • Reduce operations overheads and simplify provisioning of new services
Promotes the global development of optical internetworking products Recognized by ITU-T Study Group 15 is the focal point for studies on optical and other transport networks, systems and equipment. OIF and ITU-T Collaboration • Ethernet architecture and services Recommendations • ASON Recommendations for Optical Signalling and Routing • Transport Recommendations for GFP, LCAS, VCat • Carrier Requirements • Interoperability Experience • Protocol Specifications in OIF UNI and ENNI • Adoption of ITU-T Recs.

How big a deal is this? The 20 companies participating in the OIF Interoperability demo had $240 billion revenues in 2004 Source: Ovum-RHKNote: Vendor revenues include ON and switching and routing revenues only; service provider revenues are global wireline only
Significance of 2005 OIF Demonstration • Implementation-focused: OIF Implementation Agreements are targeted at practical, real-world development and test details • Demonstrates maturity and interoperation of control plane specs, vendor solutions and test methods • Provides critical proving ground needed for carriers to gain confidence in deploying the technology • Allows end users to access carrier optical network services using low cost Ethernet interfaces • Allows carriers to offer Ethernet services using their legacy SONET/SDH infrastructure • Gives vendors market opportunities for Ethernet, SONET/SDH and other equipment
