  12. Technical Highlights • The network consists of over 70 nodes from 13 vendors in the 7 carrier labs across 3 continents • Equipment includes Ethernet switches, routers, MSPPs, SONET/SDH cross-connects, OADMs, ROADMs • Ethernet Services demonstrated: • Ethernet Private Line service • Enabled by OIF optical control plane • Virtual Ethernet services (Virtual Private Line, Virtual Private LAN, Internet Access/Virtual Trunking) • Enabled by VLAN tags

  13. Global Topology

  14. Making it Happen • Demonstration Timeline • Spec completion • Formal commitments • Intra-lab testing begins • Global testing begins • Base spec defined • Initial event planning • SuperComm demo 2005 June* 4Q04 Jan Feb March April May • Test content defined • Verbal commitments • Equipment installed • Signaling network in place • Regional testing begins • Global testing completed * After demonstration, technical results and potential enhancements to specs are provided by OIF to other organizations (e.g. ITU-T, IETF, MEF)

  15. Architecture Model Ethernet Client Carrier A Domain Ethernet Client Carrier B Domain Carrier C Domain OIF E-NNI OIF E-NNI OIF UNI OIF UNI NE NE NE NE NE NE UNI-C UNI-N Carrier C Domain • User-Network Interface (UNI): signaling interface for clients to request services from optical network • External Network-Network Interface (E-NNI): signaling and routing interface providing call/connection control and topology • Domain edges provide interworking between vendor-specific Internal NNI (I-NNI) and OIF UNI-N/E-NNI protocols Vendor 2 Domain Vendor 1 Domain I-NNI OIF E-NNI NE NE NE NE • Domains can be advertised as • Multiple exposed border nodes with virtual intra-domain links (vendor 1) or • Single abstract node (vendor 2)

  19. 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

  20. 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

  21. 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.

  30. 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

  31. 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
