In this research we have dealt with a new and modern type of networks, namely, Software Defined Networks, which were created to overcome the negatives and challenges faced by the existing traditional networks by separating network intelligence from switching devices and placing it on external controllers, and this provides a simpler environment for programming, network management and greater software freedom To determine network behavior. There are currently many controller applications available, in this paper we compared the performance of two open source controllers which are POX and Opendaylight using mininet emulator and D-ITG tool in terms of average flow delay and throughput and which of the two controllers was more stable with increased load through Measurement of the jitter parameter in a number of basic network architectures to determine which controller has the best behavior.
