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 my favorite, the one and only Open Source Think Tank where this year we dive into the not-so-small world (there is plenty of room at the bottom!) of machine-to-machine (m2m) and Open Source, that some call the Internet of Everything.
There is a lot more to March Madness, of course, in the case of Open Source, a good time to celebrate the 1st anniversary of “Meet Me on the Equinox“, the fleeting moment where daylight conquered the night the day that project Daylight became Open Daylight. As I reflect on how quickly it started and grew from the hearts and minds of folks more interested in writing code than talking about standards, I think about how much the Network, previously dominated, as it should, by Open Standards, is now beginning to run with Open Source, as it should. We captured that dialog with our partners and friends at the Linux Foundation in this webcast I hope you’ll enjoy. I hope you’ll join us in this month in one of these neat places.
As Open Source has become dominant in just about everything, Virtualization, Cloud, Mobility, Security, Social Networking, Big Data, the Internet of Things, the Internet of Everything, you name it, we get asked how do we get the balance right? How does one work with the rigidity of Open Standards and the fluidity of Open Source, particularly in the Network? There is only one answer, think of it as the Yang of Open Standards, the Yin of Open Source, they need each other, they can not function without the other, particularly in the Network. Open Source is just the other side, the wild side!

ONS summit 2014 starts Monday March 3, and for me it is my first time here. It hardly feels that way. For us in Cisco ACI (Application Centric Infrastructure) team, it is busy last few days as we are putting final touches to showcase our exciting ACI solutions, demos and presentations to customers at this premier SDN event. Early in 2014, Cisco ACI expert Mike Cohen has made insightful predictions on what awaits SDN in 2014 – Read his Blog
Mike zeroes in on key Data Center use cases for SDN, starting with Application Deployment Acceleration securely and at scale. No one can disagree with this. L4-L7 services chaining for physical and virtual devices is another killer use-case Mike enlightens the reader with, and at the ONS Solutions Expo this year, we are showing exciting demos to illustrate service automation using dynamic L4-L7 service chaining. Do not miss out our demos at Cisco Booth 302. We are also showing demos focused on Open Stack integration with ACI, another area of growing interest.
I strongly recommend you to attend Mike’s Theater presentation titled, “Role of Policy in SDN” on March 5, 12.40 PM. Learn all the benefits and value-props that a declarative policy based ACI approach brings to network operations that is today crippled by imperative management, lack of scalability and flexibility. You will be excited to discover how our Cisco ACI team is working with Open Stack, Open Daylight initiatives and driving an open eco-system. Mike will also touch on how ACI helps bring visibility across both physical and virtual infrastructures, and how today’s SDN network overlay problems can be overcome. Shashi Kiran posted a fantastic blog on SDN overlays in ACI deployments, last week, and it makes compelling read in the context of Mike’s session.
We wish you a great ONS summit this year and look forward to seeing you at Cisco Booth 302

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.

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.

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.
