Assured service has been proposed within the differentiated services architectures to provide relative service differentiation by attempting to allocate bandwidth to different users in a controlled way during periods of network congestion. In this paper, we analyze the assured service scheme by means of a priority queueing system with state-dependent service scheduling based on thresholds. We consider the case of two classes of priority, carry out a mathematical analysis and numerically obtain the average delay endured by packets in each priority class and the loss probability for each class.
