On the Implementation of Adaptive Flow Measurement in the SDN-enabled Network: A Prototype

The measurement is an important issue in network management. The measurement results are able to provide helpful information for network administrators. Operating issues such as traffic engineering and traffic accounting also rely on the basis of it. However, the trade-off between accuracy and overhead has to be under consideration. Nowadays, though the Software-Defined Networking technology has been widely changed and made new approaches on the network architectures, montoring the traffic is still a crucial task. This paper presents a group-based flow monitoring scheme to adaptively measure flows in the SDN-enabled network. According to the designed algorithms, the sampling frequency is adjusted from time to time. By doing this, the measurement becomes more adaptive and efficient. This paper also presents a demonstration of the design. The paper aims to illustrate the idea and to share the experience of designing an alternative way for flow measurement in the SDN-enabled network.
