OpenDaylight Summit Recap

Posted by eckelcu Aug 10, 2015

The OpenDaylight Summit 2015, Santa Clara, July 27-31, was my first OpenDaylight summit. It was a great experience. I was particularly impressed with the cooperation and collaboration among the various stakeholders and vendors at the event. Rather than marketing their own solutions, presenters focused on technical content and how they are partnering with other companies and communities to deliver new functionality on top of OpenDaylight or add a new component to OpenDaylight. Here are some  sessions I attended that had particularly good content for developers:


Giles and I received positive feedback on the talks we provided as well (see previous blogpost).

Please share/comment regarding your overall impression of the conference and any sessions you found particularly good.

What's better than Buy 1 Get 1 Free?

Buy 1 Get Two Free, of course!


August 17-19 in Seattle, LinuxCon, CloudOpen, and ContainerCon come together to provide just such an offer.

Get Ship Done - Charles Eckel, Cisco & David Tootill, Cisco

Monday, August 17, 2:20-3:10pm


Developers are driving the market for cloud consumption and leading each industry into the new era of software defined disruption. There are no longer questions about elastic and flexible agile development as the way to innovate and reduce time to market for businesses. However, physical and cloud Infrastructure does not enable application development platforms natively nor provide the ability to create applications that are cloud native with elastic services. In addition, businesses are moving to application development architectures leveraging microservices, which are becoming more strategic to their business strategy. When making the decision to build and operate an application on physical or on a cloud platform, microservices became central to your application architecture and strategy.


This presentation will clearly define what a microservices infrastructure is and how it enables elastic, flexible, and portable application workload deployment.  It introduces Cisco's cloud-based Shipped product that addresses these continuous evolving needs, and includes a demo of using Shipped to set up a development project and deploy it to the cloud in minutes, including creation of associated source repositories and continuous integration builds. Lastly it introduces DevNet (, Cisco’s developer program, which provides resources to help you learn about and start using Shipped and other Cisco technologies to develop your own innovative applications quickly.


Getting Started with OpenStack - Charles Eckel, Cisco

Wednesday, August 19th - 10:25am - 11:15am


Hearing a lot about OpenStack and want to check it out for yourself? See how quick and easy it is to install and start using OpenStack within a VM on your own laptop. Acquaint yourself with the environment. Learn your way around Horizon (GUI) and the CLI to view and operate an OpenStack cloud, both from the perspective of a cloud administrator and as a tenant/user of the cloud. See how to automate typical workflows such as deploying a new multi-tier application. Best of all, take what you learn with you and experiment on your own to discover all OpenStack offers you.


See you there!

IETF 93 in Prague kicked off with a Hackathon the weekend of July 18-19. Following the success of the first IETF Hackathon at IETF 92 last March, Cisco DevNet and the IETF teamed up again to host the second edition of an event.

More than 135 participants formed into 18 teams working across 15 different technologies. Among the participants were many first time “IETFers” from various open source communities and universities. This was great to see, given the stated goals of the hackathon to bring running code back into the IETF, bridge the gap between open source and open standards, and introduce more developers and young people to the IETF. It was a huge success by these and other measures, establishing the hackathon as a valuable and vibrant addition to the IETF community going forward.

The hackathon featured technology relevant to many IETF working groups (e.g. 6tisch, ace, bier, dane, homenet, httpbis, mptcp, netvc, netconf, sfc, sidr) and corresponding open source projects (e.g. Dalla, Kea, OpenDaylight, OpenDNSSEC, OPNFV, Quagga, RIOT, SPUDlib).

How Does it Work?

The hackathon began at 09:00 with technology “champions” introducing  each technology and proposing sample projects. Next, champions and participants self organized into teams, including some with participants from multiple IETF working groups and open source communities. This mix of people, ideas, and cultures gave rise to some of the most interesting projects and highlights the opportunity for long term benefit that extends well beyond that achieved over the weekend.

Motivated by altruistic aspirations, participants worked cooperatively and diligently, developing the standards that provide the internet’s foundation in parallel with open source implementations that validate these standards and makes them easier for others to consume.

Those without conflicts with other IETF activities stayed for dinner, and many worked late into the night, well beyond the advertised closing time of 21:00. Of course this is not to say that the day was void of fun. There was of course plenty of that as well.

There was no loss of enthusiasm the next morning, with many people arriving before the advertised start time of 09:00. A few new faces arrived, their travel plans or meeting conflicts not allowing them to participate the previous day.  They were welcomed, plugged into existing teams in some cases, and formed new teams in others.

The Presentations

By mid afternoon Sunday, teams switched gears to present what they had accomplished to their peers and a 2015  IETF Hackathon Prague 065.jpgset of esteemed judges - Jari Arkko (IETF Chair), Ray Pelletier (IETF Administrative Director), Rick Tywoniak (Director of Cisco DevNet), Martin Thomson (IETF draft author and tireless contributor).

The judges were left with an unenviable task given the vast array of projects (e.g. some tests, some experiments, some implementations of protocols, and some new services).

At stake were bragging rights and first dibs on tech goodies that included Raspberry Pis, Arduinos, and a bunch of IoT accessories, plus tickets denoted by Brocade to the IETF social event Tuesday.


Among the winners were three projects the judges awarded “Best of Show”:


  • ACE – Key Technology Award
  • DNSSEC – Broadest Coverage Award
  • HOMENETBest WiFi Router Feature Award and the Cool Kids Award

The awards ceremony concluded the hackathon, but the payoff for all the great work was yet to come. Hackathon projects were shared more broadly with the IETF community at an extremely well attended Bits-N-Bites session Thursday evening. IMG_2921.JPG

Results and insights from projects were fed into working group sessions held throughout the week.

One of the best examples was the NETVC working group meeting.


Nathan Egge, Mozilla –

"Over the course of two days a team of 11 participants (both local and

remote) hacked on the Thor and Daala codebases, two open source video

codecs that have been contributed by Cisco and Mozilla respectively to

the NETVC working group.  The results of the hackathon included adding

support for Thor to the testing framework,

running 4 different experiments using Thor's motion compensation within

Daala, and fixing a long-standing issue in Daala by adding the CLP

post-processing filter from Thor.  We had Cisco committing to Daala and

Mozilla committing to Thor, which truly shows the collaborative spirit

of the IETF.  Having a hackathon is an excellent way for new ideas to be

tested out in running code and NETVC will be back for the IETF 94

hackathon in Yokohama.”


The complete set of technologies and projects, as well as photos and a video summary are available via the event Wiki.

From the main hackathon page, its easy to navigate to the Wiki from the IETF 92 Hackathon as well. The IETF and open source communities are encouraged to reference these sites to help with their ongoing work.


What comes next?

Good news - the IETF has already announced a hackathon at IETF 94 in Yokohama, and Cisco DevNet is on board to sponsor it yet again. Not only that, the hackathon will become a regular part of IETF meeting in 2016 and beyond. Sponsorship

opportunities exist for anyone wanting to show their support for this important effort  (contact Ray Pelletier for details). So mark your calendar, plan to arrive early, and help us have the biggest and best IETF hackathon ever, October 31 - November 1 in Yokohama.
