An extended OpenFlow model: An incorporation of initial messages in a virtual environment
This research investigates problems with OpenFlow design to monitor and manage network switches to enhance the network performance. The OpenFlow technology has provided centralised management of the network and easy deployment with more flexibility. However, a long delay of the initial connections is one of the typical issues of OpenFlow due to its procedure. This paper focuses on those issues and provides some solutions to improve the network performance. The proposed model is introduced and simulated on a virtual environment with OpenFlow. The proposed model called extended OpenFlow model (EOM) utilises initial messages to recognise the network topology and enhance the network performance. The results clearly illustrate that the quantity of messages exchanging between controller and switches increases as more hosts are connected to the network. The results also prove that the proposed design works better than the existing methods.
