OIF Concludes SDN Transport API Interoperability TestingThe Optical Internetworking Forum (OIF (News - Alert)) conducted a six-week long global testing of the Transport Application Programming Interface (T-API) standard from the Open Networking Foundation (ONF). The OIF managed the multi-location demonstration which started in mid-October 2016 and concluded in December 2016. Vendor participants executed a multi-domain path selection and recovery test plan with intra-lab and inter-lab testing across five carrier labs located in Asia, Europe and North America. A technical white paper on the demonstration is available to download here. "As operators move from SDN PoCs and lab trials into commercial deployments, lack of interoperability between the SDN controllers and the orchestration layer above has quickly become the biggest technical barrier for many operators," said Sterling Perrin, principal analyst, Heavy Reading. "Building a standardized northbound interface and successfully testing interoperability across different vendors and different networks - as the OIF has demonstrated - is a major step forward in addressing the northbound interface challenge and bringing SDN architectures to wide-scale commercial use." OIF SDN Transport API Interoperability Demonstration The Optical Internetworking Forum (OIF) and the Open Networking Foundation (ONF) are leading the industry toward the wide scale deployment of commercial SDN by testing key Transport Application Programming Interfaces (T-API). The interoperability test and demonstration, managed by the OIF, addresses multi-layer and multi-domain environments in the following carrier labs; China Telecom, China Unicom, SK Telecom, Telefonica (News - Alert) and Verizon. These carriers defined real world use cases including multi-domain orchestration of services delivered through Ethernet, OTN and optical switching. Carriers and vendors demonstrated how Virtual Network Functions (VNF) and SDN configured connectivity are combined to deliver service life cycle management. Participating vendors include ADVA Optical Networking, Ciena, Coriant (News - Alert), Huawei Technologies Co., Ltd., Infinera, Juniper Networks, NEC Corporation, Sedona Systems, and SM Optics. Consulting carriers include Orange (News - Alert) and TELUS. Academic and/orresearch institution participants include China Academy of Telecommunication Research (CATR) and Centre Tecnològic de Telecomunicacions de Catalunya (CTTC). Additional information can be found here. Participants in the OIF Transport SDN interoperability event also submitted a proof of concept demo proposal to ETSI NFV. The proposal, "Mapping ETSI-NFV onto Multi-Vendor, Multi-Domain Transport SDN", was accepted and details are located here. The open demonstration of NFV concepts in a Proof of Concept (PoC) helps to build industrial awareness and confidence in NFV as a viable technology. Proofs of Concept also help to develop a diverse, open, NFV ecosystem. Results from PoCs may guide the work in the NFV ISG by providing feedback on interoperability and other technical challenges. "Being able to dynamically establish connectivity between Virtual Network Functions enables carriers to provide greater service agility and reduce opex," said Jonathan Sadler, of Coriant and the OIF Interoperability chair. "Integrating multiple technologies using transport SDN further enables the right connectivity mechanisms used for service delivery. Having this demonstration recognized by ETSI NFV provides building blocks for the development of future SDN-WAN."
Public Read-Out Event at OFC 2017 "SK Telecom (News - Alert) is delighted that we have successfully tested interoperability using SK Telecom's Transport Infra Orchestrator and T-API. The test proves that standardized T-API can be used to control multi-layer, multi-vendor transport network infrastructure in an integrated manner," said Park Jin-hyo, Senior Vice President and Head of Network Technology R&D Center at SK Telecom. "SK Telecom will continue to make efforts to develop 5G and network virtualization technologies to realize Network as a Service (NaaS)." About the OIF The OIF facilitates the development and deployment of interoperable networking solutions and services. Members collaborate to drive Implementation Agreements (IAs) and interoperability demonstrations to accelerate and maximize market adoption of advanced internetworking technologies. OIF work applies to optical and electrical interconnects, optical component and network processing technologies, and to network control and operations including software defined networks and network function virtualization. The OIF actively supports and extends the work of national and international standards bodies. Launched in 1998, the OIF is the only industry group uniting representatives from across the spectrum of networking, including many of the world's leading service providers, system vendors, component manufacturers, software and testing vendors.
