Open Daylight

It’s been almost a year since Cisco publicly unveiled its Application Centric Infrastructure (ACI). As we’ve noted in the past, ACI had to overcome a number of preconceived notions about Software Defined Networking (SDN), and without some detailed explanation, it was hard to get your head around how…

[Note: This is the third a four-part series on the OpFlex protocol in Cisco ACI, how it enables an application-centric policy model, and why other SDN protocols do not. Part 1 | Part 2 | Part 4] The Cisco ACI fabric is designed as an application-centric intelligent network. The Cisco APIC policy mod…

I am delighted to announce a new Open Source cybergrant awarded to the Caltech team developing the ANSE project at the Large Hadron Collider. The project team lead by Caltech Professor Harvey Newman will be further developing the world’s fastest data forwarding network with Open Daylight. The LHC ex…

In this week’s episode, Nils Swart (@NLNils) and Stace Hipperson (@stacehipperson) discuss how data becomes information via Open Daylight. Have they whiteboarded network engineer nirvana? Watch and see. More data! This is in fact unicorns in a distance. Foiled again: This is Engineers Unplugg…

March is a rather event-laden month for Open Source and Open Standards in networking: the 89th IETF, EclipseCon 2014, RSA 2014, the Open Networking Summit, the IEEE International Conference on Cloud (where I’ll be talking about the role of Open Source as we morph the Cloud down to Fog computing) and…

First Open Daylight Summit took place exactly one year since we’ve started the project, to the day! Ah, those memories of having to stay quietly patient, from our first meeting, February 4th, 2013, and longer… in hindsight, talking about it after the code actually started to flow was mor…

With the announcements on NX-OS APIs, Application Centric infrastructure APIs, python scripting support, SDN, open source projects OpenStack, OpenDaylight, and Puppet, I have opened an account at codecademy.com and will start with Python and Java. I see many late nights in my future. This stubborn o…

Perhaps I’m in the minority that is still frustrated by this, but as a marketing person who is tasked with explaining technology and solutions to customers and prospects, I feel hamstrung by a lack of a widely agreed upon definition of what is and is not “SDN” still. This usually comes up in discuss…

Well Cisco has done it. I have worked in IT since 1995 and never learned programming. Sure, I can do a little HTML, and years ago, I learned just enough Perl to configure MRTG, but I have never written a program. The good old CLI has kept me very busy and brought home the bacon. With the announcemen…
