OpenDaylight Unleashes Hydrogen to the Masses

The OpenDaylight Project today announced that its first open source software release Hydrogen is now available for download. As the first simultaneous code release cross-community it has contributions across fifty organizations and includes over one million lines of code. Yes. ODL > 1MLOC. For those of you interested that’s approximately two hundred and thirty man-years of work completed in less than twelve months.

It was around this time last year that the media started to pick up on a few rumors that something may be in the works with software-defined networking and controllers. I remember our first meeting at Citrix where the community started to collaborate on The OpenDaylight Project and come to common ground on how to start something this large. We had multiple companies and academics in the room and many ideas of where we wanted this project to go but there was one thing we had in common: the belief and vision to drive networking software innovation to the Internet in a new way and accelerate SDN in the open; transparently and with diverse community support. Each of us had notions of what we could bring to the table, from controller offerings to virtualization solutions, SDN protocol plugins and apps to solve IT problems. Over two days at Citrix we looked at things from a customer perspective, a developer perspective and ultimately and arguably the most important, a community perspective. From there The OpenDaylight Project emerged under the Linux Foundation. As I look back I want to applaud and thank the companies, partners, developers, community members and the Linux Foundation for driving such a large vision from concept to reality in less than twelve months, which is an incredible feat in itself.

Hydrogen is truly a community release. Use cases span across enterprise, service provider, academia, data center, transport and NfV. There are multiple southbound protocols abstracted to a common northbound API for cross-vendor integration and interoperability and three editions have been created to ensure multi-domain support and application delivery as well as deployment modularity and flexibility for different domain-specific configurations. These packages have a consistent environment yet are tailored to domain and role-based needs of network engineers, developers and operators.

  • The Base Edition, which includes a scalable and multi-vendor SDN protocol based on OSGi, the latest (and backward compatible) OpenFlow 1.3 Plugin and Protocol Library, OVSDB, NetConf/Yang model driver SDN and Java-based YANG tooling for model-driven development.
  • The Virtualization Edition (which includes the Base Edition) and adds Affinity Metadata Service (essentially APIs to express workload relationships and service levels), Defense4All (DDoS detection & mitigation), Open DOVE, VTN, OpenStack Neutron NorthBound API support and a virtual tenant network offering.
  • The Service Provider Edition (again, including the Base Edition) that also offers the Metadata Services and Defense4All but includes BGP-LS and PCEP, LISP Flow Mapping and SNMP4SDN to manage routers, gateways switches.

More information can be found on the website with regards to the releases and projects themselves.

I want to stress the importance of how well the vision has been delivered to date. I’ve been involved in multiple standards-bodies and in open source discussions in the past but this is truly one of the largest undertakings I’ve seen come together in my entire career. OpenDaylight developers have been coding day and night to get this release out the door and it’s amazing to see the collaboration and coherency of the team as we unite to deliver on the industry’s first cross-vendor SDN and NfV Platform. In addition and frequently not mentioned is that many of the protocols listed in the Editions above are also standardized at organizations like the IETF during the same period. Code and specs at the same time. It’s been a long time since rough consensus and running code has been the norm.

Over here at Cisco we’re fully committed to OpenDaylight. We’re currently using it as a core component in our WAN Orchestration offering for service providers to allow intelligent network placement and automated capacity and workload planning. The ACI team (formerly Insieme) collaborated with IBM, Midokura and Plexxi to create a project in OpenDaylight that creates a northbound API that can set policy and be used across a wide range of network devices. And of course we’re bringing components of the OpenDaylight codebase into our own controllers and ensuring application portability for customers, partners and developers alike. From this I would expect to see more code donations going into the community moving forward as well. We made several announcements last week about our campus/branch controller that includes OpenDaylight technology.

At the end of the day an open source project is only as strong as its developers, its community and its code. As we as a community move forward with OpenDaylight I expect it to become stronger with more members joining with new project proposals as new code contributors coming onboard from different industries as well. As I look at our roadmap and upcoming release schedule I’m pumped for what’s next and so happy the community has catalyzed a developer community around networking.

Please do visit the site, download the code and take Hydrogen for a test-drive. We want to hear feedback on what we can make better, what features to add or how you’re going to utilize it. Moreover, we’d love you to participate. It’s a kick-ass community and I think you’ll have fun and the best part; you’ll see your hard work unleashed on the Internet and across multiple communities too.

Annual Employee Giving Campaign Generates Nearly $6 Million for Global Hunger Relief

Christina O’Neill is a manager with Cisco Community Relations based in Research Triangle Park, North Carolina, who oversaw Cisco’s 2013 record-breaking Global Hunger Relief Campaign.

 “We make a living by what we get, but we make a life by what we give.” – Winston Churchill

In its 11th year, Cisco’s 2013 Global Hunger Relief Campaign proved more than ever that our desire to do the right thing goes beyond the confines of our traditional work responsibilities. Cisco’s annual campaign ran from November 4th through December 31st, and our results were record breaking!

Cisco employees directly donated $2.3 million in the fight against hunger around the world.  All employee contributions were matched twice – once by the Cisco Foundation and once by Chairman Emeritus John Morgridge’s TOSA Foundation – tripling the impact of every gift and bringing total donations to $5.8 million, distributed through 162 hunger relief organizations around the world.  The impact of the dollars raised translates to 23 million meals served! As part of the campaign, we were able to partner with Cisco’s disaster relief efforts after tragedy struck the Philippines at the beginning of November, sending food relief via our campaign to help victims of Typhoon Haiyan.

Why I Chose the Open Source Model I did for OpenDaylight

Now that OpenDaylight has arrived, it’s time to explain why I made the Open Source choices eventually embraced by its Founders and the community at large.  One doesn’t often see such leaders as Cisco, IBM, Intel, HP, Juniper, RedHat, VMWare, NEC, Microsoft and others agree, share and collaborate on such key technologies, let alone the latter engaging in a Linux Foundation based community (some thought hell will freeze over before that would ever happen, though it got pretty cold at times last Spring).

For those of you not familiar with OpenDaylight (see “Meet Me On The Equinox”, not a homage to Death Cab for Cutie or my Transylvanian homeland), IBM and Cisco have actually started this with an amazing set of partners, nearly that ephemeral Equinox this year (~11am, March 20th) though we couldn’t quite brag about it until all our partners saw the daylight, which by now, we’re hoping everyone does.  It was hard not to talk about all this as we saw those half baked, speculative stories before the Equinox – amazing how information flew, distorted as it were, but it did; I wish source code would be that “rapid”, we’d all be so much better for it…

The Open Source model for OpenDaylight is simple, it has only two parts: the community is hosted in the Linux Foundation and the license is Eclipse.  The details are neatly captured in a white paper we wrote and published in the Linux Foundation.  Dan Frye, my friend and fellow counterpart at IBM and I came up with the main points after two short meetings.  It would have been one, but when you work for such giants as our parent companies and soon to be OpenDaylight partners, one has to spend a little more time getting everyone to see the daylight.  It boils down to two things, which I am convinced are the quintessential elements of any successful open source project.

1) Community.  Why?  Because it trumps everything: code, money and everything else.  A poor community with great code equals failure (plenty of examples of that).  A great community with poor (or any) code equals success (plenty of examples of that too).  Why? Because open source equals collaboration, of the highest kind: I share with you, and you with me, whatever I have, I contribute my time, my energy, my intellectual property, my reputation, etc.. And ultimately it becomes “ours”.  And the next generation’s.  Open Source is not a technology; it’s a development model.  With more than 10 million open source developers world wide, it happens to be based on collaboration on a scale and diversity that humanity has never experienced before.  Just think about what made this possible and the role some of the OpenDaylight partners have already played in it since the dawn of the Internet.  Dan Frye and I agreed that the Linux Kernel community is the best in the world and so we picked the closest thing to it to model and support ours, the Linux Foundation.

2) Fragmentation, or anti-fragmentation, actually.  Why?  The biggest challenge of any open source project is how to avoid fragmentation (the opposite of collaboration).  Just ask Andy Rubin and the Android guys what they fear the most.  Just ask any open source project’s contributors, copyright holders, or high priests, how much they appreciate an open source parasite that won’t give back.  Though we would have liked to go deeper, we settled on Eclipse, largely because of the actual language and technology we dealt with in the OpenDaylight Controller: most, if not all the initial code is Java, and though some are worried about that, I’m sure Jim Gosling is proud (btw, I’m not sure the Controller has to stay that way, I actually agree with Amin Vahdat), but we had to start somewhere.  Plus having a more friendly language NB (northbound, as in the applications run on top of the Controller) is such a cool thing, we think that the #1 open source (Eclipse) and the #1 commercial (Microsoft) IDE’s are going to be very good to it, so why not?  There are more reasons that pointed in the Eclipse direction, and other reasons for such wonderful alternatives (as APL or MPL, perhaps the subject of another post, some day).  But when it comes to understanding the virtues of them all, no one understands them better than the amazing founders of these license models, most of them from IBM, of course (I wish they did that when I was there).

What happened between the Equinox and Solstice is a fascinating saga within the OpenDaylight community which I think played its course in the spirit of total and complete openness, inclusion, diversity, respect of the individual and the community, and most of all, that code rules – we do believe in running code and community consensus.  I tip my hat to all my fellow colleagues that learned these two things along the way, the enormous talent at the Eclipse and Linux Foundation that helped us launch, and even the analysts who tried (and did incredibly well at times) to speculate the secret reasons why these partners came up with the model we did: there is no secret at all, my friends, we’re simply creating a community that is truly open, diverse, inclusive, and never fragmented.  Just like a big, happy family.  Welcome to OpenDaylight, we hope you’ll stay!
