What is SDN simulator?
The software defined networking is abbreviated as SDN and this approach is utilized in the open protocols including the OpenFlow to apply the globally aware software control in the edge of networks towards the switches in the accessing networks. The SDN simulator is utilized as the control packet to forward all the three layer devices in the network through the functions of modules based on SDN in the networks including LTE, VANETs, MANETs, WSN, IoT and internetworks. The three types of layers are listed below,
