Open Daylight Shines in Impressive Debut

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 more appropriate, the 2013 Spring Equinox, as it should. The Open Daylight community has shown that code is the coin of the realm, as it should. To walk that talk, a million lines of code are flowing now and for a project with partners and committers as diverse as this, one cannot do that unless there is a strong tie that binds, the commitment that the best multi protocol controller will be open source: as Linux achieved that status in the OS world, OpenDaylight has a bright opportunity to do so in the network world. As for the bad news, there aren’t any: yes, we would like to see ourselves talk more about use, before we talk about our size, but for a one year old, I think we should be patient.

The outstanding news for this young project is the community diversity, energy and commitment: it brings the best protocol (SB) guys in the world with the best scientists and network (NB) developers in the world in a focused, collaborative, engaged community. Remember, in open source, community trumps code, which side by side with its project sovereignty, is nothing but a formula for success. That is what sets Open Daylight apart, and as long as we take care of those two things, it will be fine. As I said last week during the event, particularly good to see Google, Intel, Ericsson, Microsoft, Cisco, IBM, RedHat and others doing their presentations celebrating this event. I am proud of these guys, how they lead the way for any other Open Source project interested in leveraging the network (be it Open Stack, Open Compute Project, or others), Linux Foundation and Open Daylight is the best way to stay ahead, to stay engaged: if you are interesting in networking and open source, there is no other better place than this.

Summary: Cisco is bringing together networking and programming

January 29, 2014 at 9:00 am PST

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 old networker is finally onboard.

Is ACI Really SDN? One Point of View to Clarify the Conversation

January 22, 2014 at 10:00 am PST

Would SDN, by any other name, still smell as sweet?

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 discussions about our new Application Centric Infrastructure (ACI), and how it compares to traditional SDN concepts, as well as alternative approaches, such as overlay networks advocated by VMware.

The topic came up again this with a NetworkWorld article in which the head of VMware’s network virtualization business is now saying, “SDN will never happen” (our rebuttal). Well, what is happening, if it’s not SDN? Or just because the technology has evolved, do we need to create a new term just because some early assumptions the industry made have changed?  As we start out a new year, I thought it a good time to try and reframe the definition, and look at how the trends in SDN may be shaping up to extend the concept into new areas.

Why do customers need SDN?

By early 2012, there was so much hype and expectations around Software Defined Networking, focused on the ability to “program” the network, that real customer use cases and the killer SDN app was lost in the conversation. But what slowly emerged, that is driving all the investment, pilots and product designs is a much better way to manage the data center and cloud network, and to automate IT tasks so that the infrastructure could respond dynamically to rapidly changing business conditions and requirements. The “intelligence” to make all that happen is moving from the network devices and device management consoles, to centralized policy-management platforms, orchestration tools and cloud-managers.

What’s caused the biggest evolution in SDN is the realization that very few organizations really have the desire, skills and incentives to write a new class of applications to a published API to program the network. These users are outlying use cases compared to the vast majority of organizations just looking to automate IT tasks, accelerate application deployment, make their cloud networks more flexible, and better align their IT infrastructure with business requirements. The focus has shifted from SDN being an open API/controller platform, to a platform capable of hosting a myriad of orchestration and IT workflow automation solutions that drive customers to their end goal. To that end, ACI is meeting all those objectives, and in more advanced and innovative ways than earlier SDN approaches.

Cisco is bringing together networking and programming

January 16, 2014 at 11:03 am PST

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 announcements on NX-OS APIs, Application Centric infrastructure APIs, python scripting support, SDN, and open source projects OpenStack, OpenDaylight, and Puppet, I cannot hold back anymore.

Therefore, I have opened an account at codecademy.com. I will start with Python and Java. I see many late nights in my future.

I have thought about learning code, but I could never think of an app I wanted to write. Now Cisco is bringing together networking and programming. Cisco is not only making APIs available, Cisco is contributing code to the open source community. In fact, Cisco has created a Data Center repository, a Nexus 9000 community, and a general Cisco Systems repository on GitHub.

DevNet

Cisco has recently overhauled the developer program and its content. The new DevNet website is filled with developer information on products such as AVC, Collaboration, UCS, CTI, Energywise, FlexPod, UCS Microsoft Manager, Jabber, onePK, XNC, Telepresence.

Cisco is bringing the networking and programing worlds together and this stubborn old networker is finally onboard.

Happy Coding!

Open Source in the Network

Join me and my good friends Dan Frye and Jim Zemlin, Tuesday June 18th at 8:30 am Pacific, in a webcast as we discuss open source, networking, communities and projects, the opportunities entailed, the win-win-win model (or win-cube model as I like to call it, for the Authors, for the Community and for the Enterprise), and the recently announced Open Daylight project hosted by the Linux Foundation.  Thank you, Shashi Kiran, for organizing a wonderful event and opportunity to talk about one of my favorite subjects, Open at Cisco.
