7 El objeto de este trabajo es describir las posibilidades que ofrece el sistema operativo LINUX, dentro del ámbito de redes de computadores, centrándose en el tema de control de tráfico, específicamente se hará un barrido sobre temas como los conceptos básicos de la teoría de colas en las redes de computación, las herramientas del kernel de Linux que definen las clases, políticas y filtros para el control de tráfico, la administración del ancho de banda en una red de computadores y los elementos que en ella intervienen. En el primer capítulo se hace una breve introducción a la teoría de colas, sus modelos matemáticos, características y tipos de colas, para terminar con la presencia de las colas en los sistemas de comunicaciones, mas exactamente con las redes de computadores. En el segundo capítulo se define el concepto de control de Tráfico en general, y se hace una revisión detallada de los elementos relacionados, tales como colas, flujos, paquetes y de los mecanismos usados para control de tráfico, independiente de los sistemas operativos como son: scheduling, policing, Clasifying, etc. Igualmente se hace una aproximación mas detallada del tema de disciplina de colas, haciendo énfasis en aquellas que tiene aplicabilidad en el campo de control de tráfico. En los capítulos 3 y 4 se aborda el tema de enrutamiento avanzado con LINUX, y su aplicabilidad al control de tráfico, presentando las herramientas con que cuenta el sistema operativo con Kernel 2.4.x.+, incluyendo IPTABLES e IPROUTE2. Esta última herramienta ya contiene la utilidad tc que es la que en LINUX permite hacer el control de tráfico, aplicando los conceptos vistos en capítulos anteriores, tales como disciplina de colas, clases y filtros. En el capítulo 5 se toma un caso de estudio y mediante la metodología de práctica de laboratorio, se realizan diferentes acciones de control de tráfico sobre una pequeña red. Dichas acciones obviamente son realizadas mediante un sistema operativo LINUX, y mediante la medición hecha con herramientas de monitoreo de tráfico se comprueban los resultados esperados /
