  • Software Defined Network (SDN) is a network architecture which separates control plane and data plane. Focus of this research is discusses Bellman-Ford algorithm in determining the shortest path, as well as a QoS single topology and custom topology using parameters throughput, delay, packet loss refers to standardization ITU-T G.1010. Bellman-Ford algorithm is implemented on a POX controller and tested in a custom topology. Scenario is source host sends packet to destination host using PING command, then when packet delivery is in progress a traffic engineering link failure is made such as link down. Based on tests that have been done, it can be concluded that Bellman-Ford algorithm applied in custom topology SDN network is able to find other shortest paths as alternative paths based on number of hops shortest between switches. For QoS results in a single topology, throughput smallest TCP 720 Kbps and largest TCP 758 Kbps, while smallest UDP 695 Kbps and largest UDP 729 Kbps. Delay value single topology smallest TCP 0,00670 s and largest TCP 0,00705 s, while smallest UDP 0,01142 s and largest UDP 0,01199 s. Packet loss value single topology smallest TCP 0% and largest TCP 0,00383%, while smallest UDP 0% and largest UDP 0,01596%. In custom topology, throughput smallest TCP 431 Kbps and largest TCP 497 Kbps, while smallest UDP 413 Kbps and largest UDP 460 Kbps. Delay value smallest TCP 0,01016 s and largest TCP 0,01168 s, while smallest UDP 0,01690 s and largest UDP 0,02015 s. Packet loss value smallest TCP 0,00052% and largest TCP 0,02363%, while smallest UDP 0% and largest UDP 0,06445%. Based on results of QoS tests that have been obtained, it can be concluded that a SDN network single topology and custom topology has good QoS performance which refers to standardization ITU-T G.1010.
