Different from traditional data traffic, multimedia traffic has stringent requirements on quality of service (QoS). For multimedia networking, a prime concern is to ensure that there are adequate network resources to meet the QoS requirements of multimedia traffic. In order to make effective traffic and congestion control, and network management, in-service QoS monitoring and estimation (ISME) has to be employed as opposed to the conventional out-of-service monitoring and testing techniques. In this paper, an ISME scheme is proposed. Virtual buffer techniques are employed in the ISME scheme to reduce the monitoring time required to make a valid observation of QoS. Simulation using both voice traffic source model and real variable bit rate video traffic is performed. Simulation results show that the proposed scheme is able to achieve better accuracy than that in the literature. Moreover, it also requires less monitoring time than that in the literature.
