Implementación del modelo diffserv (QOS) en un entorno de tráfico real para evaluar el comportamiento de parámetros de calidad de servicio en equipos cisco y mikrotik.

Abstract

The objective of this Curricular Integration work was to evaluate the behavior of the parameters of bandwidth, latency, packet loss, jitter and cpu, by implementing a real traffic environment on two scenarios of Mikrotik and Cisco equipment. The generation of real traffic was implemented through the TRex tool, which allowed the creation of a client and server traffic environment focused on the Streaming and Web service. The TRex generator was implemented in a virtual machine, with two network cards. Client and server connectivity between the two core routers was established using static routes. The implementation of the DiffServ Quality of Service model was carried out through the stages of identification, marking in the DSCP field of the IP header and establishment of policies for traffic treatment. The identification stage was carried out using the Omnipeek tool in order to classify the generated traffic. The marking and treatment stage focused on the form of configuration for each brand. For the analysis of results, the T-Student test was used through a comparative study of parameters in both brands before and after applying the DiffServ Service Quality model. Based on the results obtained and analyzed, a significant difference can be seen in bandwidth, latency and packet loss with a difference between the average values of 0.1502 Mbps, 39.56 ms and 14.4352 percentage respectively between the brands before applying the Quality model. Service DiffServ. After applying the DiffServ Quality of Service model, the bandwidth and jitter presented a significant difference between both brands with a difference in their average values of 0.0844 Mbps and 0.162 ms respectively.
