SDN interactive manager: An OpenFlow-based SDN manager

Currently, many investigations addressed SDN management considering using monitoring information for different purposes. Zhang [1] used monitoring information to develop algorithms for anomaly detection and traffic engineering. Jose et al. [2] used the same monitoring information to propose mechanisms for online measurement of large traffic aggregates. Yu et al. [3] proposed FlowSense, which is aimed to keep the lowest control channel overhead and the highest information accuracy as possible in OpenFlow monitoring. Chowdhury et al. addressed SDN monitoring from a different perspective. The authors proposed Payless [4] framework that is able to deal with monitoring considering the polling frequency and data granularity. Payless relies on OpenTM [5] to select only important switches to be monitored, also aiming to reduce the overhead imposed in the control channel. Thus, this framework allows to adjust the polling frequency parameter to balance the control channel overhead, imposed by monitoring messages, and accuracy of monitored information.
