Abstract: Today network works under several problems. To solve these problems OpenFlowbased programmable software-defined network (SDN) was released. Datacenter network is one of the application areas that required successful integration of distributed controllers. However, the need for high-performance SDN controllers' increases with the increasing of network devices in the datacenter network. SDN distributed controller allows to increase or decrease the number of controllers regarding the change of traffics. The aim of this paper is performance analysis of SDN distributed controllers in datacenter networks. Initially, compared distributed controllers and selected ONOS (Open Networking Operating System) controller. Then, created three ONOS controllers in a cluster and designed tree topologies. Following tested and evaluated three ONOS controllers' throughput and latency and presented the results of single, two and three ONOS controllers performance. Finally, based on these results the distributed ONOS controller has better performance than single SDN controllers in datacenter networks.

Keywords: software-defined networking; SDN distributed controller; OpenFlow; open networking operating system; datacentre networks; tree topologies.
