Abstract(in English)	It is generally believed that Intserv model is more suitable for strict QoS guarantees than Diffserv model because the former has per-flow-base traffic handling mechanisms but the latter does not. This general belief, however, has not been fully verified yet. In this paper, we theoretically and numerically compare Intserv and Diffserv models in terms of jc-percentile end-to-end queueing delay as well as the maximum end-to-end queueing delay. We find that, in some network topology, Diffserv architecture makes the maximum queueing delay smaller than Intserv architecture. We also find that in most cases Diffserv makes x-percentile queueing delay much smaller than that in Intserv-based networks.
