  1. OIF UNI/NNI Interoperability Demo

  2. Overview • OIF Interoperability Goals • University of New Hampshire Testing • Interoperability topologies and test Methodology • UNH testing and outcomes • OFC’2003 Public Demo • Conclusions

  3. OIF Interoperability Agreements: Timeline Decision to focus initially on UNI UNI 1.0 approved, NNI req. work starts First NNI proposals & Interim NNI NNI routing & signaling baseline spec. First UNI 1.0 draft ballot UNI Interop Event UNI/NNI Interop. May 2000 Jan 2001 May/June 2001 Oct. 2001 Jan. 2002 Jul. 2002 Mar. 2003

  4. UNI/NNI Interoperability Goals • Proof of concept of the OIF (Inter-domain) E-NNI concept • Validate the UNI/NNI interworking solution • Demonstrate maturity of UNI 1.0 Agreements

  5. UNI and NNI: Definition and Placement Switched Connection: initiated by clients over UNI interface Soft Permanent Connection (SPC): initiated by management agent Optical Transport Network Control domain UNI NNI UNI Client Network (IP, ATM, SDH) NNI Control domain NNI Control domain UNI UNI - User to Network Interface NNI - Network to Network Interface

  6. UNI/NNI Interoperability Trial Assumptions • Interoperability agreements are based on • User Network Interface (UNI) 1.0 Signaling Specification (IA, OIF2001.125.7) • NNI Implementation Agreement Proposal for OFC 2003 (OIF2002.476) • Connections are established dynamically over • an UNI initiated interface (switched connections) or • an EMS/NMS initiated interface (soft permanent connections) • The test network topologies refer to clients and domains. Each domain could represent either an individual TNE (Transport Network Equipment) or a vendor domain containing multiple TNE devices • Explicit routing is provided by the first metro or core node initiating the network connection • Inter domain link dissemination • Testing focused on control plane only

  7. Protocol Overview • Signaling • RSVP-TE • RFC 3209, 3471/3473 • G-UNI object (esp. TNAs) as in UNI 1.0 • Multi-session RSVP and SPCs as in oif2002.353 • Routing • OSPF-TE • RFC 2328 and gmpls, sonet/sdh extensions • Domains and TNA reachability as in oif2002.023 • Interoperability Goals • Interoperable multivendor signaling and routing • SPC and UNI connection setup • Domain abstraction

  8. Relationship with GMPLS • GMPLS – Generalized MultiProtocol Label Switching • A set of IETF standards for Sub-IP Control Plane • Signaling: RSVP-TE and CR-LDP • Routing: OSPF-TE and ISIS • Link Management • Current limitations • Restricted to single routing area – limited scope • Limited support of hierarchy or abstraction • Future • Multi-area extensions

  9. Relationship with ASON • ASON – Automatic Switched Optical Networks • A set of ITU-T standards for Optical control plane • G.8080 ASON architecture • G.7712, 7713, 7714, 7715 ASON requirements • G.7713.1/2/3 and G.7714.1 protocol specs • Top-down design • Carrier-based requirements • Multi-domain model • Alignment with NNI • Signaling aligned • Routing tbd

  10. Interoperability Participating Companies • Alcatel (UNI-C, UNI-N, E-NNI, NMS/EMS) • Avici (UNI-C) • Ciena (UNI-N, E-NNI) • Data Connection (UNI-C, UNI-N, E-NNI, NMS/EMS) • Elematics (UNI-N, E-NNI) • Mahi Networks (UNI-N, E-NNI, NMS/EMS) • NEC (UNI-C, UNI-N, E-NNI) • Motorola/Netplane (UNI-C, UNI-N, E-NNI, NMS/EMS) • Nortel (UNI-N, E-NNI) • Sycamore (UNI-N, E-NNI, NMS/EMS) • Tellabs (UNI-N, E-NNI, NMS/EMS) • Tellium (UNI-N, E-NNI, NMS/EMS)

  11. Test Methodology • Round robin approach - random vendor pairings /grouping • create diversity and fairness • maximize partner/interoperability exposure by exhaustive pairing • Testing Steps • Routing establishment among the network devices • Signaling are tested with UNI initiated and EMS/NMS initiated connections • Network build out are based on results from daily test progress

  12. Interoperability Network

  13. OFC’2003 Highlights • OFC 2003 • First time ever in the industry to successfully demonstrate multi vendor UNI/NNI interoperability; demonstrated set up and removal of 15 LSPs across multi-domain network in real time; • Participated by 12 vendors with 15 types of product of real network equipment or simulated nodes • Network topology with 10 network client devices and over 30 simulated network elements in 12 domains • Signaling and routing information exchanges was captured and updated in the real time with display software to reflect dynamic connection establishment

  14. UNI/NNI Signaling Display

  15. NNI Routing Display

  17. InteroperabilityTest Event at UNH

  18. OFC2003 Interoperability Demo Participants

  19. Conclusion • Summary • Early planning and weekly technical team calls identifies interop issues ahead of time • Extensive test rotations at UNH closed door testing • Commitment from all interop participants (9 day, 12 – 18hr/day) • Next Steps • Accelerate protocol development with discussion on the Interoperability Finding document (oif2003.035) • NNI spec • UNI 1.0 impact • Share ideas with Carrier WG on value added features and applications
