The Performance Analysis of Hybrid SDN–IP Reactive Routing on ONOS Controller in Tree Topologies

Abstract

Software Defined Networking (SDN) is a new concept for managing a computer network. In the implementation, the SDN network has difficulties connecting with a traditional IP network. The Open Network Operating System Controller (ONOS) has an application for connecting SDN networks and traditional IP networks via BGP, which is SDN-IP. SDN-IP will convert the BGP route packets obtained from BGP Speakers into intents. The ONOS controller will process these intents into an Openflow route which will be forwarded to the data plane. Reactive SDN-IP routing computes and creates traffic paths between the SDN network and the traditional IP network so that both networks can communicate with one another. Hybrid SDN is an SDN network, and a traditional IP network runs side by side. This research will test the Quality of Service on the Hybrid SDN network with two scenarios. Results of network quality measurement show that the use of the TCP protocol produces an average throughput value of 52.9836 Mbps and a delay of 0.15096 ms in the scenario of a traditional IP network to an SDN network, which is better than a traditional IP network to a traditional IP network over an SDN network.
