Análisis comparativo del desempeño de las arquitecturas GPON y R-CORD mediante simulación, considerando parámetros de latencia, jitter, throughput y perdida de paquetes.

Abstract

Optical access networks have had to become more flexible, adaptable, and efficient because more and more users are demanding high-speed digital services. Given this context, this research conducts a comparative analysis of the performance of classic GPON and R-CORD (residential central office reconfigured as a data center) designs in FTTH environments, using a computational simulation methodology. This thesis employs a quantitative methodology focused on modeling uplinks, identified as the main point of congestion in PON networks. To do this, we created a simulation environment in Python that recreates real-world multi-class traffic situations (VoIP, video, and best effort) under the same controlled conditions for both architectures. We analyze basic quality of service (QoS) metrics such as average latency and percentiles (p95, p99), jitter, throughput, packet loss, link utilization, queue length, and Jain's fairness index. This shields critical traffic better and prevents performance from getting worse. The results support the hypothesis, as they demonstrate that R-CORD virtualization and disaggregation are a technically sound way to modernize FTTH networks, providing them with greater operational flexibility and better quality of service than traditional GPON architectures.
