Abstract This paper presents a new numerical method to analyse steady‐state TCP throughputs in DiffServ networks. Different TCP models are briefly reviewed, and a Markov chain is used to capture the behaviour of a multi‐random early detection (RED) queue. The established closed network model couples models for TCP, marking device and multi‐RED queue. We assess accuracy and limits of the technique, and apply it for a discusion of parameter settings for marking devices. Copyright © 2005 AEIT.
