Jaringan uji menggunakan topologi Full-Mesh yang menyediakan koneksi penuh ke semua switch, dimana terdapat dua protokol layer transport yang digunakan untuk mengirimkan data dalam jaringan SDN yaitu TCP dan UDP.

The speed in processing the flow table requests that are made by the switches depends on the choice of the type of controller used. There are several types of controllers that can be used to manage the data traffic flow in the SDN network. This research utilizes the RouteFlow controller and the Djikstra routing algorithm. The test network applies the Full-Mesh topology that provides fully connections to all switches, wherein two transport protocols are used to transmit data in SDN networks, i.e., TCP and UDP. The results of network performance measurements show that the use of the UDP obtains better values in delay, jitter, and throughput than TCP.
