A comparison between several Software Defined Networking controllers

摘要

The networking industry faces nowadays with the emergence of a somewhat revolutionary paradigm that is intended to rethink network architectures, with the intention to mitigate the limitations that appeared in the traditional networks: Software Defined Networking (SDN). This paper illustrates differences between some SDN controllers, which represent the “brains” of the network. POX, Ryu, ONOS and OpenDaylight are the SDN controllers for which a comparison between their performances is made, using the mininet simulation environment.
