Comparing Open Source SDN Controllers, like OpenDaylight, OpenContrail, and ONOS is a challenge. In Part 1 we compared commercial SDN controller vendors. First you, have to understand the what makes up an SDN Controller. Here in part 2, we’ll compare open source SDN Controllers. In a software-defined network (SDN), the SDN Controllers is the “brains” of the network. It is the strategic control point in the SDN network, relaying information to the switches/routers ‘below’ (via southbound APIs) and the applications and business logic ‘above’ (via northbound APIs).
The open source SDN Controllers are consider a platform that typically contains a collection of “pluggable” modules that can perform different network tasks. Some of the basic tasks include inventorying what devices are within the network and the capabilities of each and gathering network statistics. Extensions can be inserted that enhance the functionality and support more advanced capabilities, such as running algorithms to perform analytics and orchestrating new rules throughout the network.
There are a variety of Open Source SDN Controllers under development, from POX to Beacon, which is one of the most popular. Started in early 2010, Beacon is a Java-based OpenFlow Controller licensed under a combination of the GPL v2 license and the Stanford University FOSS License Exception v1.0. Other SDN Controllers of note include Trema (Ruby-based from NEC), as well as Ryu (supported by NTT).
