The centralized routing decision offers excellent flexibility in a network environment. Moreover, it has an impact on the robustness of the distributed protocol. As one of the computer architecture, Fibbing offers the protocol flexibility and robustness through central control of the routing to be distributed. By making fake nodes and fake links in the network, Fibbing delivers minimal overhead and a quick reaction to network and controller failures. However, the original Fibbing architecture results in an excessive number of LSA packets are caused by fake nodes and fake link injection. In this research, we analyze the performance of Fibbing by using the isolation domain in the Hybrid software-defined network (SDN) environment in terms of the network quality based on the latency and throughput when sending information packets from the source to the destination nodes. The results show that the isolation domain provides better efficiency in the evaluated parameters.
