Existing Tools Achieving Interoperability Challenges for Developing Common APIs Current API work is being done in fragmented silos Some linkage of APIs to existing protocol environments Keys to achieving interoperable common APIs Define standard model across vendors and technologies Common Information model is key to interoperability ONF has led a Common Information Model project aligning ONF, ITU-T, TMF, MEF, OIF modeling Verify APIs provide the necessary functionality Use case review and convergent SDO work Prototype, Demonstrate, Test Code!
OIF Interoperability Demonstration &Testing 2014 OIF Transport SDN Demonstration OIF/ONF Interop Demonstration 5 carriers worldwide Multiple HW and SW vendors Equipment in carrier labs Optical and Ethernet switch domains Some testing of OpenFlow optical extensions Multi-domain network Prototype common API provides access to domains Higher level orchestration across domains 2014 Demonstration

OIF 2016 SDN T-API Interop Demo What and Who: OIF is managing the demo, partnering with ONF on technical work Open to OIF and ONF members as well as non-members Carriers: China Telecom, China Unicom, SK Telecom, Telefonica, Verizon System vendors: ADVA, Ciena, Coriant, Fiberhome, Huawei Technologies Co., Ltd., Infinera, Juniper, C Corporation, Sedona, SM Optics, ZTE Why: Help enable wide scale deployment of commercial SDN by testing the recently approved ONF Transport Application Programming Interface (T-API) The interoperability test and demonstration will address multi-layer and multi-domain environments in global carrier labs Builds on 2014 demo which was based on prototype T-APIs and helped advance transport SDN standardization Additional use cases based upon the API standards will be clarified during the testing and defined through OIF implementation agreements to provide a common set of requirements When, Where, How: August-Sept: Technical spec development October-November: Carrier-hosted lab testing 1Q17: Demo read-out events and white paper
Next Steps Interoperability is technically feasible, as demonstrated in labs, but still missing from commercial products The OIF will help carriers unlock the benefits of SDN for their optical networks through three interrelated programs: Interop demonstrations hosted by participating operators leveraging key interfaces such as the Transport API to bind together multi-layer and multi-domain carrier networks; Implementation Agreements that document the use of industry standards; Coming soon - a new program to address the gap between paper specification or early implementation and products that carriers can deploy. The new program, along with well established and successful interop testing and IA process, will help realize commercial transport SDN deployment and the promised benefits of accelerated time-torevenue coupled with increased operational efficiency
