Guía referencial para el manejo de QoS en redes WLAN prioritizando tráfico

Abstract

The implementation of QoS policies can address various points depending on the requirements of the WLAN; for example, the allocation of bandwidth in a differentiated way, avoiding or managing congestion on the network, managing priorities according to the type of traffic, etc. As a function of the analysis of the traffic, QoS policies can be established that enable the prioritization of the traffic type (http, ftp, ssh) according to the user needs in line with the objective of the WLAN. To do this a WLAN scenario is performed without prioritization of traffic and with traffic prioritization, using an application designed to manage service quality in wireless networks: FROTTLE, software for analysis of traffic on the WLAN as ntop, wireshark, program echoping, hping3. The results obtained allow us to demonstrate the improved quality of service to prioritize traffic so that the indicators show satisfactory levels. A reference guide was developed to manage the quality of WLAN service based on a prioritization of traffic.
