To Maximize The Value Of SD-WAN, Look Past Hardware Savings
/ Oct 6, 2015 0 COMMENTS

I moderated a workshop on the topic of software defined WANs (SD-WAN) last month and I’m continually baffled that the focus of software-defined networking remains on the hardware for so many individuals. This is clearly a hangover from the early days of SDN when many of the start ups were hammering home the point that…

What’s Up with the ONF?
/ Sep 29, 2015 0 COMMENTS

The Open Networking Foundation (ONF) is the organization that is most closely associated with the development and standardization of SDN. As of September 2015, the ONF had over 140 members. Given its size and its tight association with SDN, in order to understand where we are with the evolution of SDN we have to be…

Evolving the network to a next-generation architecture is all the rage now. A digital business needs an agile, dynamic network to use as a foundation for innovation, so the network must now evolve. This is one of the reasons my fellow analysts and I are pushing the concepts of SDN, broadband WAN, and Network Functions…

ONS Shows the Status of SDN in the Enterprise
/ Jul 21, 2015 0 COMMENTS

There were over 1,300 attendees at the recent Open Networking Summit (ONS) in Santa Clara making the ONS one of, if not the largest SDN-focused conference in the world. Because conferences such as the ONS provide good insight into what leading-edge users are doing, it’s interesting to ask: What were the leading edge enterprise users…

In the 2015 version of the Network Purchase Intention Study run jointly by ZK Research and Tech Target, one of the questions we asked about the WAN was “What WAN Issues Does Your Organization Need to Address?” The top three answers were issues that most organizations face when it comes to running a WAN. The…

Is Moore’s Law Going To Be Repealed?
/ Jun 30, 2015 0 COMMENTS

I recently attended the Open Networking Summit in Santa Clara. During a morning keynote session one of the speakers started to discuss his company’s SDN architecture, and made a comment on how that architecture is impacted by the fact that Moore’s Law is either dead, or soon will be dead. It was early in the…

Despite the mounting frustration with MPLS, many customers still do not believe the Internet can provide the security and performance needed for today’s business-critical traffic. And while current conversations around leveraging the Internet for the enterprise WAN have focused primarily on the ability to use multiple network connections, and in some cases, zero-touch provisioning, we…

How Can You Go From WAN Theory to SD-WAN Reality?
/ Jun 11, 2015 0 COMMENTS

In the last few months a lot of articles have been written about the WAN in general, and about Software-Defined WANs (SD-WANs) in particular. These articles typically point out the well-known limitations of the current approach to wide area networking and discuss how to apply a variety of techniques, both old and new, to the…

How will SDN and NFV Standards Really be Developed?
/ Jun 2, 2015 0 COMMENTS

Most people like standards because they believe that standards lead to something they really want, which is interoperability. I have been a member of three different standards committees, one of which was sponsored by the European Computer Manufacturers Association (ECMA). At one ECMA meeting, a 45 minute discussion broke out about the proper format for…

Don’t Get Attached To SD-WAN
/ May 21, 2015 0 COMMENTS

For some time now, SD-WANs (Software Defined Wide Area Networks) have been the subject of much hype and discussion in the networking community.  Outsiders most likely get a chuckle at yet another acronym created by data networking enthusiasts: “SD-WAN”. Don’t get attached to SD-WAN — the acronym, that is — since it may go the…
