<![CDATA[Software-defined Networking (SDN) is a new paradigm in computer network management that separates the control plane and data plane. The controller is an important component in an SDN-based computer network. The purpose of this research is to conduct a comparative study of the performance of segment routing and reactive routing in SDN. In this study, ONOS was chosen as the controller used in the experiment because it supports the implementation of segment routing and reactive routing. The experiment of implementing the two routing protocols on an SDN network with a full-mesh and tree (depth 5) network topology is the scenario that is tried in this study. QoS results based on TIPHON parameters (throughput, packet loss, delay and jitter) were recorded from each experiment. The throughput of each experiment was 6.97 MB/s, 5.80 MB/s, 1.65 ms and 2.16 ms, indicating index 4 (very good). Packet loss in the full-mesh topology experiment was 5.16% and 5.53% with index 3 (good), while in tree (depth 5) the results were 2.46% and 2.16% showed index 4 (very good). The delay for each experiment was 2.99 ms, 3.17 ms, 4.65 ms and 5.43 ms, indicating an index of 4 (very good). The jitter for each experiment was 7.10 ms, 7.85 ms, 18.30 ms and 18.13 ms, indicating index 3 (good).]]>
