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.

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.

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.

My App anywhere: On devices, on controller, on both!

January 29, 2014 at 12:41 am PST

Current differences in app development on devices and controllers disappear. Devices and controllers will share a common programming environment – offering a unified development and deployment experience.

While SDN is moving from concept to reality, we notice that many deployments which focus on creating new network features interpret the role of the “controller” very pragmatically. In these deployments, the controller is not used as an independent layer of software which abstracts the entire underlying infrastructure as in the traditional view of SDN (see for example ONF’s SDN Definition). The pragmatic approach to network programming simply extends the distributed development environment of the network devices using a set of qualities offered by the controller.  Developers move those components of their distributed apps to the controller that benefit from the logical centralization or the enhanced resources (CPU, memory) that a controller typically offers while keeping other components on the network devices. Example use cases fall into the categories of distributed network analytics, DDoS thread mitigation, or routing optimization based on performance measurements. What does this mean for our development environment?

New Year, New Challenges, New Successes: SDN Bringing Agility, Security and TCO to Campus and Branch Networks

Before recently taking on a new role as Cisco’s vice president and general manager of Software-Defined Network (SDN) with the enterprise networking group, I served as the vice president and general manager of Cisco’s Unified Access portfolio and led the expansion of the Catalyst 2k, 3k and 4k series product line, which has seen a lot of growth and developed a strong customer base over the past couple of years. Cisco invests heavily in R&D for these products, and has introduced many innovations improving security, application visibility/control, energy savings and converged wired and wireless infrastructure over the past few years.

But as I shifted into my new role and looked back at some of the new Unified Access solutions we introduced alongside our system architecture, I saw a curious disconnect: in some cases, it was getting more difficult for our customers to quickly take advantage of our new innovations.                                                                                                         

At Cisco, we design products to make customers’ lives easier and more productive. Not to gather dust because they’re too hard to figure out!
