Software Defined Network (SDN) is an emerging approach in network technology appeared in recent years. In the SDN revolution, OpenFlow is defined as the first communication standard to separates the control plane and data plane this allows the control plane to be centralized by an OpenFlow con-troller. The rise of SDN and OpenFlow has changed the point of view of the conventional model for network devices. In this paper, we focus on QoS moni-toring in SDN controller using OpenFlow protocol. We propose a monitoring method for collecting the statistic and calculating the throughput of link traffics. We also design a new forwarding algorithm for control plane that avoids bottle-neck and provides load-balancing. To evaluate our algorithm in real time traffic, we setup a test-bed in Mininet where we design the applications using the devised algorithm in Opendaylight controller, a fully functional open-souce project with a rich set of API.
