  1. OIF Challenges: Enabling Broadband On-Demand Services

  2. Agenda • Service Drivers, Challenges and Transformations in Network Infrastructure • OIF Development and Test of Interoperable Networking Solutions • OIF 2009 Worldwide Interoperability Demonstration

  3. Service Drivers, Challenges and Transformations in Network Infrastructure

  4. Service Drivers and Challenges • Users demanding lower cost, converged and personalized services • Broadband services with high performance, feature richness, dynamic control and reliability • Complexity in networks, services, vendors and markets • Increasing network diversity in: • Industry standards • Carrier models • Product architectures • Need for vendor innovation while preserving interoperability

  5. Optical Network TransformationA Work in Progress • Key drivers • Convergence • Operational efficiency • Availability Data CapacityFeature richness • Key drivers • Service assurance • Bandwidth optimization • Automation • Key drivers • Capacity • Performance • Reliability Transparent photonics NG-SONET/SDH ASON/GMPLS ROADM SONET/SDH rings DCS WDM pt-to-pt Packet-based Transport ASON/GMPLS OTN Tunable ROADM Past Today Future • Much attention is on emerging technology, yet carriers must deliver services over diverse networks based on legacy, contemporary and cutting edge technologies. • There is no universal convergence layer or technology that meets everyone’s requirements

  6. DCN DCN ASON Architecture and OIF IAs • ASON architecture addresses the transport network evolution • Heterogeneous network topologies, technologies, and applications • Diverse internal control plane protocols, including management-based • Separation of transport and control planes • OIF complements the work of optical standards bodies • Implementation Agreements (IAs) based on standards • Interoperability testing and prototyping of solutions Management plane Domain A Domain B Domain C Client Client Control plane E-NNI E-NNI UNI UNI NM • Each domain can use either management or control plane internally • Control plane topology can differ from transport plane topology Transport plane NE NE NE NE NE NE NE NE NE NE NE NE • Transport technology and topology can differ in each domain

  7. OIF Development and Test of Interoperable Networking Solutions

  8. OIF UNI and E-NNI Development * E-NNI does not directly support Ethernet bearer interfaces but can carryEthernet services adapted into SONET/SDH or OTN signals

Core nodes typically operate in single server layer • Supports non-disruptive modification (BW or VLAN IDs) to meet varied demands of client while in-service • Versatile – supports only layers needed (e.g Eth-VCAT-SDH, packet over WDM) yet supports multiple layer adaptations • Server layer call/connection signaling flow completes before client layer

  15. OIF 2009 Worldwide Demonstration FeaturesHigh Level Technical Objectives • EVPL over diverse transport technologies • End-end domain-based service restoration • Simultaneous control plane and data plane testing • Wide range of signal formats and data rates • Switched connections (with UNI-C) and soft permanent connections (no UNI-C, triggered by management device) • Connections set up over both pre-provisioned and dynamically established server layer trails • Graceful and forced teardown • Vendor I-NNI interworking with UNI 2.0 and E-NNI 2.0 • Test buildup from lab-local to regional to global scope

  16. OIF 2009 Worldwide Demonstration FeaturesExamples of Detailed Technical Objectives • EVPL over connection-oriented packet transport • Uni- and bi-directional connections • EPL, EVPL type 1, 2, 3 and E-tree • Packet-based forwarding, multiplexing, QoS, OAM and protection (both failure-induced and user-initiated) • Restoration • Triggers: node failure, inter/intra domain link failure, user command • E-NNI based restoration flow using upstream Notify message and make-before-break process • Intra-domain or end-end multi-domain restoration • Failed resource identification to support diverse restoration • Signaling to coordinate traffic roll between working and protection paths
