Open. Daylight One open source SDN controller to rule them all Open. Daylight, an open source software defined networking SDN controller, aims to tear down the barriers to SDN adoption in the enterprise. SDN controllers allow the separation of flow control i. A to point B from the physical network hardware. At a recent Software Defined Data Center SDDC symposium, Neela Jacques, the Executive Director of Open. Daylight, said enterprise network managers are fully aware of the benefits of SDN, but they are reluctant to commit to an SDN controller amongst the confusion. He says the two primary reasons for the lack of SDN adoption are technology fragmentation and duplication of efforts. A number of controllers have hit the market, and there are many more in development. The list includes open source projects Open.

OpenDaylight Lithium SR3 with Apps v1 now availableFlow, Open. Contrail, and the soon to be released Cisco Application Centric Interface ACI, which is proprietary. VMwares NSX has its own controller as well. Despite the long list of controllers, there are currently no standards that allow interoperability of controllers and underlying hardware. If a new open source project or vendor wants to create a new controller, it must work with each hardware provider independently. It has taken years for the major providers to support Open.

Jacques argument is that this has basically frozen enterprise network managers in their decision making process about SDN. The Open. Daylight projects promise is to unite all of the controllers by offering a standard that network hardware providers and other software controllers can embrace. The OpenDaylight Project is a collaborative open source project hosted by The Linux Foundation. Unveil Lithium Upcoming OpenDaylight Release. OpenDaylight. Once Open. Daylight becomes that standard northbound interface, other controllers can leverage Open. Daylight to gain consistency across multiple vendors. The argument is rooted in the fact that Open. Daylight is open source and, therefore, not a threat to traditional network vendors. The idea is to build an ecosystem similar to Open. Stack, where vendors flock to Open. Daylight as part of a thought leadership land grab. Open. Daylights technical and political challenges. The question for early adopters is How mature is the platform Similar to the early years of Open. Stack which is only four years old as of this writing, the Open. Daylight project is very ambitious the effort to create a single controller to rule all other controllers is daunting, and there are technical and political challenges. Open. Daylight is actively looking for contributors to help bring it to the maturity level where it can become a supported project. The project has to convince the industry that their vision is the right one to rally around. There has been some success with Extreme Networks recently announcing support and several vendors, including Cisco, as major contributors to the project. Supporters are quick to tell potential end users that this is still a beta level solution. Conclusion. If your organization is starting to look into SDN and isnt pressured to deliver on the promises of SDN, I think Open. Daylight should receive some of your research resources. However, if you want to gain the competitive advantages promised by SDN, I recommend looking at a more mature controller such as Open. Flow or NSX and keeping your eye on Open. Daylight and potentially integrating it into a future revision of your SDN infrastructure. Automatically subscribe to Tech. Republics Data Center newsletter. Installing Mininet, Open. Daylight and Open v. Switch Network. Static. The easiest way to get started with a quick SDN lab image is using the Mininet image that is now managed by the ONLAB which is part of the ONRC. They do a nice job keeping the images maintained. Ideally the will incorporate ODL into the image soon since the ODL GUI is great for folks to get started with SDN. You can use your prefered hypervisor of choice to run the image. The Mininet guide has instructions for each. Download Mininet and get the image up and running with the following guide Download and Get Started With Mininet. Open v. Switch should already be running when you boot mininet. You can stop and start the process with etcinit. Stop the controller if you are using ODL for control. Performing the following will get Open. Daylight up and running on your mininet instance or you can run it on the host OS or any other with IP connectivity. It is a simple two node network. If you run into issues head to the opendaylight irc channel on irc. From Mininet run the following apt getupdateapt getinstall maven git openjdk 7 jre openjdk 7 jdk unzipwget https jenkins.

They are doing some interesting stuff with network topologies and also expanding Mininet to a multi node distribution. Open. Daylight Tech Work Stream See the September 3.
