(English Abstract)
When Quality of Service (QoS) is supported by flow path control in Software-Defined Networking (SDN) environment, the current simple least cost path finding method can cause inefficient rerouting problems. The measured performance of the flow path derived based on the link quality may differ from the predicted performance. In particular, in the case of sequential QoS condition search for candidate paths, the effectiveness of path-based QoS support may decrease due to repeatedly searching for the same path previously identified as the final path. In this paper, we propose a learning-based QoS path search model. The model learns the path that finally satisfies the QoS conditions according to the network state, and predicts the QoS path for the network state when rerouting is required. The experiment shows that this learning model can reduce unnecessary path iteration search costs given the similar network conditions, and is more effective than other learning-based models in a service environment that requires rapid QoS quality restoration.
