Evaluación de la calidad de enlaces de telecomunicaciones a través de herramientas de estimación del ancho de banda disponible en redes de computadores heterogéneas

Currently, the global network "Internet" has been the medium through which companies, universities, schools, homes and individuals carry out telecommunications activities. The infrastructure of Internet provider companies faces new challenges every day due to the growth in demand with more content, such as video streaming, webinars, virtual classes, data processing, storage, and cloud processing. Given the high data consumption at present it has been difficult to maintain optimal levels of quality of service, network applications demand more telecommunications resources. Although the network infrastructures that support these applications have evolved, there is a need for greater and more efficient administration of the trunk links, which play a primary role in sustaining services. To evaluate the quality of telecommunications links in heterogeneous computer networks with the support of Available Bandwidth Estimation (ab_bw) Tools, is to find the values that allow improving the performance of various protocols and applications that can be implemented in heterogeneous networks. To estimate the ab_bw, the current tools insert test packages in addition to those already existing on the network. This additional traffic in a network is called Overhead, which will allow the bandwidth estimation analysis tools to be intrusive when using part of the channel bandwidth that they are measuring. In this project, the performance evaluation of the trunks, wired and wireless will be carried out in a heterogeneous computer network infrastructure, using available bandwidth estimation tools such as IGI, Pathload and Traceband. Thus, for the experimental evaluation of the links, two real network scenarios were implemented, where the cross traffic was generated synthetically using the Mgen tool. This study verified that the metrics of the estimation tools can be used to evaluate and know the performance of wired and wireless links, which can be up to 96% reliable for network administrative tasks.
