and technology• Application to carriers

• Interop Testing in carrier labs• 5 carriers worldwide• 10 HW and SW vendors

• Multi-domain network needs• Diverse SouthBound (NE)

Interfaces, e.g., OpenFlow• Prototype common API for

end-to-end orchestration• Led to development of ONF API

Standards2014 Demonstration

OIF 2016 SDN TAPI Interop DemoIn Progress

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, NEC Corporation, Sedona, SM Optics, ZTEWhy:• Help enable wide scale deployment of commercial SDN by testing the recently

approved ONF Transport Application Programming Interface (TAPI)• 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 TAPI 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• Feedback into ONF standards and carrier planning• 1Q17: Demo read-out events and white paper

OIF UNI Certification ProjectFrom Testing to Certification

Issue to be solved : Multi-vendor interoperability of the optical control plane is still missing from commercial products, although various demonstrations have proven it is feasible.

Certification is a powerful tool to bridge the gap between technical standards and commercial implementations: it will provide a unique reference and a market advantage to compliant, interoperable products.

è In line with its mission is to enable global interoperability in optical transmission networks, OIF surveyed the market and decided to create a certification program for interoperable products – starting with the Optical Control Plane UNI.

Centralized and distributed control

Centralized and distributed controls are complementary and need to interwork with each other, as to ensure end-to-end coordination across heterogeneous networks.

Advantages as a starting point for certification: mature technology, known market drivers, standalone feature and existing area of OIF expertise Can be followed by future NNI, SDN API and other areas for certification

UNI certification deliverables and timeline

Timeline for OIF to deliver the UNI Certification :

Development of the UNI certification test specification is starting now.Testing of participating products will start early 2017.First certified products will be on the market in ~12 month from now.

Value to the industry

◆ Means for operators to obtain and differentiate interoperable commercial products

◆ Market advantage to manufacturers’ products which pass certification

◆ Reduced repetitive testing for vendors and operators. Time to market.

◆ Enhanced implementations, better competition, more innovation.

Operators: make sure to mandate the OIF certification in all your upcoming RFPs!Vendors: get involved in the OIF program and be first to ship certified products!

Survey Comments

Vendor #1: “A universal set of requirements and certifications gives us the ability for interop of components where certifications in the past used best guesses as to what parameters or metrics were important and which ones were actually tested.”

Vendor #2: “OIF certification can help broaden and accelerate the market for optical products by assuring multi-vendor/-product interoperability and thereby reducing the time to get products qualified and accepted. This reduces the sales cycle for system vendors and lessens the testing and qualification burden on service providers.”

Carrier #1: “The OIF certification will greatly facilitate integrating our IP and optical networks together. We need a control plane open to multiple vendors and multiple layers. The OIF certification will avoid the fear of vendors lock-in. On the longer term, the advent of interoperability in optical networks will increase agility and innovation, at lower costs, for the benefits of the entire industry.”

Carrier #2: “An OIF certification will enable us to guarantee the devices we buy are compatible with the latest Multi-layer interoperability features. We believe that a correct management of GMPLS-UNI interaction is the key to transport SDN at its maximum level.”

Conclusion

• The OIF helps the industry unlock the benefits of SDN for optical networks, through three interrelated programs:• Implementation Agreements, that document the use of industry

standards; • Interop demonstrations, hosted by participating operators

leveraging key interfaces such as the Transport API to bind together multi-layer and multi-domain carrier networks;

• Certification, to address the gap between paper specification or early implementation and products that carriers can deploy.

• Technical feasibility is being demonstrated through OIF interoperability testing, in addition certification will help to get technology into commercial products
