Experimenting with NETCONF connector in OpenDaylight
On the southbound, OpenDaylight has support for both NETCONF and OpenFlow for managing underlying devices. This allows your applications to manage both traditional devices with in-built control planes and the OpenFlow-enabled devices with decoupled control planes. End-to-end control and orchestration is, thus, easily achieved using […]
Experimenting with ONOS clustering
ONOS, Open Network Operating System, is a newly released open-source SDN controller that is focused on service provider use-cases. Similar to OpenDaylight, the platform is written in Java and uses Karaf/OSGi for functionality management. Recently we experimented with this controller platform and put together a […]
Docker Networking
Recently we fiddled with several of the network settings in native Docker and put together a survey presentation. It feels fascinating to realize that overlay networking is being revisited once again in the context of containers/Docker. For those not familar with Docker, it is sufficient […]
SDN starter kit based on Ryu controller platform
We are releasing a SDN starter kit software package to promote SDN trial and adoption in smaller proof-of-concept deployments. The applications are built over the Ryu controller platform. The current code base offers simple implementations of the applications / modules like topology visualization, monitoring tap management, server […]
Release of OpenFlow 1.3 support for OpenDaylight’s AD-SAL
Download OpenDaylight, thus far, has supported OpenFlow 1.3 only through Model-driven SAL. However, MD-SAL can be unwieldy at times. We solve this issue by releasing a set of bundles and source code that enable OpenDaylight users to use AD-SAL for controlling OpenFlow 1.3 switches as well […]

Teams comprised of participants from diverse backgrounds (engineers, product managers and architects, from different parts of the world (Brazil, Japan, […]
SDN Test Suite: Results for Floodlight and OpenContrail
We compared the functionality and data plane of the following three approaches for virtual networking: OpenContrail solution: This overlay-SDN solution uses BGP control plane and MPLSoGRE for the data plane. Each virtual dataplane (called vRouter) is also a full-fledged routing gateway. The snapshot of the […]
