Analysis about behavior of the throughput in LAN networks under technology Power Line Communications

Abstract

The performance is without doubt one of the aspects of greatest interest within the overall analysis in LANS, considering the effect that it produces on the end user. The performance can be defined according to various points of view, allowing to incorporate other forms of evaluation depending on the object of interest in particular. Basically, the most common parameters for evaluating the performance of a network are: Throughput, use of the channel and various measures of delay. Throughput, is defined as the capacity of a link to carry useful information. In other words, represents “the amount of useful information that can be transmitted per unit of time”. It may vary in the same network connection depending on the protocol used for the transmission (TCP or UDP) and the data type of traffic (HTTP, FTP, etc. ). One of the most important objectives to analyze the throughput is related to the quality of service (QoS / Quality of Service) on the network, which plays an important role in assessing the efficiency of a network centered in time-sensitive applications, such as: video and audio, among others. From a technological point of view, making use of the Power network as physical environment of transmission has been considered as an excellent alternative in the provision of interconnection services of last mile. The use of network adapters based on PLC facilitate the design of LANS and broadband communications through the Power network, converting any wall socket in a connection point for the user, without the need for additional wiring to the existing ones. This article presents an experimental analysis on the behavior of the throughput in LANs on PLC, under the use of network adapters supported with the standard HomePlug 1.0.
