The SDN Fault Detection Algorithm Research Based on Multi-Controller
-
Abstract
For the SDN controller fault detection algorithm is usually used fixed time interval detection method, a fault detection algorithm based on gray prediction is presented in this paper. The algorithm predicts the arrival time of the next message and sets the threshold value in an adaptive way for the dynamic change of the network. The simulation results show that the algorithm proposed in this paper can achieve fault location quickly and ensure the reliability of the detection point.
