Open Networking Foundation Selects Criterion Network Labs as its Fourth International Testing Facility

The Open Networking Foundation (ONF), a non-profit organization dedicated to accelerating the adoption of open Software-Defined Networking (SDN), today announced Criterion Network Labs (CNLabs), a vendor-neutral independent division of Criterion Networks India Pvt. Ltd., as ONF’s fourth international conformance and interoperability testing facility. CNLabs joins the University of New Hampshire InterOperability Laboratory (UNH-IOL), Beijing Internet Institute (BII), and the Indiana Center for Network Translational Research and Education (InCNTRE) in testing SDN products for compliance with the OpenFlow™ specification through the ONF OpenFlow Conformance Testing Program.

“The networking industry is undergoing a refreshing change. SDN provides a framework through which networks can be administered, programmed, and made to scale seamlessly,” said Jayaprakash Kumar, director of Criterion Network Labs. “OpenFlow provides the method for ensuring consistency, promoting device interoperability, and allowing for a level of flexibility to the network operator that has not been seen before. We are delighted to be named the first ONF-approved testing facility in India and the second in Asia.”

As an ONF-accredited testing facility, CNLabs establishes OpenFlow conformance testing capabilities in India and provides SDN testing services to global clients. CNLabs evaluates vendors’ networking products for conformance, performance, and interoperability, and offers vendors the opportunity to receive OpenFlow certification through ONF’s Conformance Testing Program.

“Our team is very excited to be a part of the vibrant ONF community, to help increase adoption of this new paradigm that is transforming the current networking landscape, and to encourage deployment of new technology and services,” said Srinivas Vegesna, CEO of Criterion Networks. “Becoming an ONF-approved lab is a significant milestone for us, which will also help in increasing SDN awareness and adoption in India as well as across our geographic region.”

In addition, Criterion Networks has also joined as a member company of ONF through the organization’s newly-announced startup membership category. ONF established this category to embrace the innovative work taking place within startups, increasing organization collaboration and the advancement of open SDN.

“We extend a warm welcome to Criterion Network Labs as the first ONF-accredited testing lab in India,” said Dan Pitt, executive director of the Open Networking Foundation. “This addition to our OpenFlow Conformance Testing Program is an exciting development for our organization, as it further strengthens our efforts to encourage interoperability, fosters application development, helps increase awareness of the benefits of open SDN, and serves to accelerate global adoption of this technology.”

The buzz continues for cloud, data analytics and the Internet of Things (IoT) and their collective impact across all industries. But a new conversation is emerging - how do companies use industry disruption and technology enablers to lead in markets undergoing change, uncertainty and ambiguity? Organizations of all sizes need to evolve and transform, often under massive pressure, as industry lines blur and merge and traditional business models are assaulted and turned upside down. In this new da...
The Internet of Everything is re-shaping technology trends–moving away from “request/response” architecture to an “always-on” Streaming Web where data is in constant motion and secure, reliable communication is an absolute necessity. As more and more THINGS go online, the challenges that developers will need to address will only increase exponentially. In his session at @ThingsExpo, Todd Greene, Founder & CEO of PubNub, exploreed the current state of IoT connectivity and review key trends and t...
Culture is the most important ingredient of DevOps. The challenge for most organizations is defining and communicating a vision of beneficial DevOps culture for their organizations, and then facilitating the changes needed to achieve that. Often this comes down to an ability to provide true leadership. As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership ab...
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now ...
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more.

Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem"...
I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.

Cloud computing delivers on-demand resources that provide businesses with flexibility and cost-savings. The challenge in moving workloads to the cloud has been the cost and complexity of ensuring the initial and ongoing security and regulatory (PCI, HIPAA, FFIEC) compliance across private and public clouds. Manual security compliance is slow, prone to human error, and represents over 50% of the cost of managing cloud applications. Determining how to automate cloud security compliance is critical...
