9. OIF UNI Certification Project
From 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.

10. 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

Can be followed by future NNI, SDN API and
other areas for certification

12. 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.

13. 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!

14. 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.”

15. 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
