Add Tag | Summary: | The present project analyzed the performance of software-defined networking (SDN) controllers in environments with real-time streaming services, with the aim of assessing their efficiency, stability, and management capabilities under different load conditions. The research followed a comparative and descriptive approach, with a quantitative and analytical focus, and a non-experimental, longitudinal design, developed entirely within an emulated environment using Mininet. Based on a comparative technical review, the controllers OpenDaylight, Ryu, and ONOS were selected, as they are considered the most representative due to their OpenFlow support, modularity, and compatibility with the aforementioned emulator. A hierarchical topology with 20 Mbps links was implemented, over which the selected controllers were integrated, and a continuous streaming service was used as the main load. The effective video bitrate was determined experimentally to ensure consistency between the generated traffic and the capacity of the links. During the tests, latency, jitter, throughput, packet loss, availability, and memory consumption were measured under three traffic load levels: low, medium, and high. The results showed that Ryu maintained the best balance between speed and stability, ONOS exhibited solid performance though with higher resource usage, and OpenDaylight displayed more variable behavior under congestion. Overall, the study confirmed that the SDN architecture represents an efficient alternative for time-sensitive services and that emulation is an effective tool for comparative evaluation of controllers in reproducible environments. |
