Performance Comparison of ONOS and ODL Controllers in Software Defined Networks Under Different Network Typologies

A controller is a fundamental component of the Software-Defined Network (SDN) architecture that will contribute to the success or failure of SDN. Although it can be implemented using different open source and proprietary tools, selecting the best would eventually contribute to the success of implementation. Therefore, there is a need to assess and compare other …
