Experimental Evaluation of Two OpenFlow Controllers
Abstract
Network management has become a tricky task in today's complex networks and distributed data centers. Software Defined Networking (SDN) provides more flexibility, eases automation, and gives a more comprehensive view of the network. In a software-defined network, traffic management functionality requires a high-performance and responsive controller.
The SDN controller, as the “brain'' of the network, enables network administrators to classify, manipulate, and dynamically re-route an evolving set of traffic flows across many possible network paths. In mission-critical networks, having a flexible and carrier-grade controller is a high priority.
In this thesis, we conduct an experimental evaluation of two open-source distributed OpenFlow controllers, namely ONOS and OpenDaylight. To this end, we construct a testbed and use a standard benchmarking tool called Cbench to evaluate their performance. We benchmark the throughput and latency of these controllers in both physical and virtual environments. The experimental results show that ONOS provides higher throughput and lower latency than OpenDaylight.
