Abstract
A network controller for delay measurement in SDN and related delay measurement system and delay measurement method are provided. A probe packet is used to record the transmission of the probe packet between the network controller and network switches, to calculate a transport delay time between the network switches and hop delay time between the network switches, to obtain the delay of each link in the transmission path, which helps in finding out a critical hop in the SDN transmission path. Through the delay measurement mechanism according to the present disclosure, the critical hop will become a reference based on which a network manager adjusts a network framework, or a basis taken by an SDN control system to select a path.
