Modelo Diffserv (Qor S) in a real traffic environment to evaluate the behavior of QoS parameters on cisco and mikrotik equipment

Abstract

This document presents the evalua tion d 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 using the TRex tool creating an environment of traffic of clients and servers focused on the Streaming and Web service, through a virtual machine, with two network cards. Routing between client-servers was established using static routes. The implementation of the DiffServ Quality of Service model was carried out through the identification stages using the Omnipeek tool, marking in the DSCP field of the IP header and establishing policies for traffic treatment. For the analysis of results, the T-Student test was used comparing the parametersbetween both brands before and after applying the DiffServ Quality of Service model. Based on the results obtained, there is a difference in bandwidth, latency and packet loss between the average values 0.1502 Mbps, 39.56 ms and 14.4352% respectively before applying the model and 0.0844 Mbps, 0.162 ms after applying it.
