Abstract In Dieren tiated Services networks, packets may receive a dieren t treatment ac- cording to their Dieren tiated Services Code Point (DSCP) label. As a consequence, packet marking schemes can be devised to dieren tiate packets belonging to a same TCP o w, with the goal of improving the experienced performance. This paper presents an analytical model for an adaptive packet marking scheme proposed in our previous work. The model combines three specic sub-models aimed at de- scribing i) the TCP sources aggregate ii) the marker, and iii) the network status. Preliminary simulative results show quite accurate predictions for throughput and average queue occupancy. Besides, the research suggests new interesting guidelines to model queues fed by TCP trac.
