Ingeniería de tráfico en redes IP

Abstract

Presenta los principales conceptos de ingeniería de tráfico en redes IP y al final un ejemplo de escenario de red para ilustrar los beneficios del uso de la ingeniería de tráfico del MPLS (Multi Protocol Lavel Switching) y QoS (Calidad de Servicio), que reduce los efectos indeseables de mezclar flujos insensibles con flujos sensibles a congestión. Se usa flujos de datos no sensibles a congestión.

lt is a we/1-known behavior that when congestion-sensitive (TCP) and congestion-insensitive (UDP) traffic share a common path, an increase in congestion-insensitive traffic adversely affects congestion-sensitive traffic's performance (e.g., due to TCP's congestion control mechanism). This tesis análise the basics concepts of the traffic engineering and uses an example network scenario to illustrate the benefits of using MPLS traffic engineering and QoS in eliminating the undesirable · effects of mixing congestion-insensitive flows with congestion-sensitive flows. We use a UDP data flow to represent a congestion-insensitive traffic f/ow and TCP data flows to represent congestionsensitive traffic flows.
