It’s challenging to understand the differences between SDN controller vendors and how to perform an SDN controller comparison. Here in Part 1, we’ll compare SDN controller vendors. In part 2, we’ll compare open source SDN controllers. To start, an SDN Controller in a software-defined network (SDN) 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 SDN Controller platform 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. Different SDN Controller Vendors such as Cisco, HPE, Juniper, Lumina, NEC, and Nuage off a range of proprietary and open sourced based SDN Controllers
