VESGA-FERREIRA, Juan Carlos; GRANADOS-ACUNA, Gerardo  e  VESGA-BARRERA, José Antonio. Evaluation of the performance of a network LAN over Powerline Communications for the transmission of VoIP. Iteckne [online]. 2016, vol.13, n.1, pp.83-95. ISSN 1692-1798.

The quality of service (QoS) is defined as the ability of a network to manage the traffic demand according to the class of service, in order to meet the expectations of the user and in accordance with a clearly established metrics, which applies even for networks with PLC technology. Faced with the need to optimize QoS in IP networks, a experimental design type mixed factorial is presented to evaluate the performance of a PLC network to the Voice over IP transmission, in terms of throughput, latency and jitter, in a residential environment and with the use of PLC adapters supported in the HomePlug AV standard. The result of the experiment not only establishes the degree of influence from the statistical point of view that you can produce the type of codec used or the number of active stations, but that allows you to identify which are the most recommended codecs to transmit voice over IP, improving the performance of the network and ensuring adequate levels of QoS.
