About the OIFMission: to foster, progress and guide the development anddeployment of interoperable products and services fortransport networks.The OIF is the only industry group that brings togetherprofessionals from the data and optical worldsOur 80+ member companies represent the entire industryecosystem:• Carriers and network users• Component and systems vendors• Testing and software companiesCollaboration and Innovation. At Light Speed.

Market Drivers for Interoperable NetworksMarket Trend/Needs Carriers face growing demand forhigh-speed, flexible, and highlyresilient transport services – regionallyand globallyCarrier Challenges Deliver end-to-end services acrossmultiple network domains• while maintaining resilience• and meeting customerexpectations (SLAs)The Need/Gap Interoperable networks that cansupport cost-effective dynamicbandwidth services - on a global scaleWhat is the Solution?

E-Line can be further divided into:• Ethernet Private Line (EPL), where an Ethernet port has dedicatedbandwidth across a provider network (no service multiplexing)• Ethernet Virtual Private Line (EVPL), where multiple Ethernet ports sharebandwidth across a provider network (service multiplexing)OIF UNI 2.0 supports both EPL and EVPL servicesThe demonstration focuses on interoperable on-demand Ethernet Services,offered under the ITU-T Recommendation G.8011.1 EPL model.

Control Plane Neighbor DiscoveryControlPlaneOut-of-band messagesOut-of-band messagesTransportPlaneIn-band (J0)messageIn-band (J0)message Discovery is a dynamic exchange of information for links brought into service –replacing manual configuration with automated “plug and play”• In-band overhead bytes (J0) describe local transport and control plane resources• Control plane entity correlates local and remote node information In-band message formats (such as Layer Adjacency) have been defined in ITU-T.• The OIF demo extended this capability with out-of-band messages for exchangingdiscovered information (a Layer Adjacency Discovery response message)• Discovery was also extended to exchange control plane information, such asidentifiers of control plane and transport plane entities, and routing area information• Results of demo should assist future discovery standards development
