In recent years, new advances in remote sensing techniques have made Digital Elevation Models (DEMs) become popular elevation data sources for delineating catchment boundaries. This application of DEMs is particularly useful in water accounting and river basin management for Vietnam, of which the river network has very high drainage density and has been facing many pressures arising from recent economic advances.

In this paper, we propose a new detection model that classifies traffic before deciding which machine learning algorithm used. The flexible processing and centralized management of Software Defined Network (SDN) controller allow deploying complex algorithms and mitigation methods quickly. By setting up a testbed, we implement our model as well as evaluating the parameters of accuracy successfully. The results show that our model is able to detect attack traffic quickly and exactly.
