Mejoramiento de la calidad de servicios (QoS) en aplicaciones de telediagnóstico basado en redes definidas por software (SDN): caso de estudio Clínica Monte Sinaí

Abstract

In a constantly evolving environment, where the efficient transmission of medical data over distance is gaining relevance, this research focuses on evaluating, quality of service (QoS) metrics using software-defined networking (SDN). The main objective is to evaluate these metrics with a view to improving packet transmission in telediagnostic applications, a critical area for QoS. To this end, specific objectives were established, ranging from the identification of optimal QoS metrics to the comparative analysis of the results. Systematically and rigorously, optimal QoS metrics for telediagnosis were identified and measured in the Monte Sinaí Clinic network (real scenario). Next, and SDN network was designed and simulated using MiniNet and the OpenDaylight controller (simulated scenario) and making use of the clinic’s topology, performing experiments in both scenarios with typical file sizes of medical images. The results indicate that the SDN scenario improves latency when using the TCP protocol, managing to transmit the complete image in the simulation, unlike the real clinic scenario. In addition, when using UDP, an improvement in terms of bandwidth, jitter and latency is observed in certain experiments. In summary, this research provides an in-depth understanding of how SDN implementation can benefit QoS in telediagnostic applications by optimizing remote medical data transmission.
