With the rapid development of various real-Time services, there is urgent need for application-Aware capabilities in realtime network to meet the higher demand for network's quality of service (QoS), security policy and so on. Accurate and cost-effective collection of flow information is needed. However, the contradiction between the real-Time, accuracy and performance cost in the passive traffic information collection mode of old board makes it difficult to build application-Aware realtime network of high-Accuracy. In this paper, we propose an agile application-Awareness network (A3N) for software-defined networks (SDN). A3N implements a flow-based self-Adaptive sampling strategy (FSS) for the incoming traffic and combines a parallel deep packet inspection (DPI) with high-performance to perceive network traffic changes. Experimental results demonstrate the proposed A3N can gain good performance with low costs, and also provide real-Time application-Aware services with deep operational visibility.
