1 Motivation and Introduction Real-time multimedia applications communicating over a packet-switched network present new challenges to the current networking technology. One of them is Quality of Service (QoS) requirement. Unlike some other network applications such as email and le transfer, which only require best-eeort service at the network layer, multimedia applications such as video-on-dem...

Real-time media servers need to service hundreds and, possibly, thousands of clients, each with their own quality of service (QoS) requirements. To guarantee such diverse QoS requires fast and efficient scheduling support at the server. This paper describes the practical issues concerned with the implementation of a scalable real-time packet scheduler resident on a server, designed to meet serv...

In this paper we examine the correlation between packet delay and packet loss experienced by a continuousmedia traffic source on the Internet. Our goal is to study the extent to which one performance measure can be used to predict of the future behavior of the other (e.g., whether observed increasing delay is a good predictor of future loss) so that an adaptive continuous media application migh...

−− In this paper we study packet delay and loss for IP data traversing the University of Auckland Internet ac− cess path. The ISP uplink of the university has been the subject of previous measurements and studies [1]. The fo− cus of this paper is to evaluate the information derived from a multipoint measurement, Auckland−VI [2], which was collected for a duration of four days during June 2001 a...

Network support for variable bit-rate video needs to consider (i) properties of workload induced (e.g., signiicant auto-correlations into far lags and diierent marginal distributions among connections) and (ii) application speciic bounds on delay-jitter and statistical cell-loss probabilities. The objective of this paper is to present a quality-of-service solution for such traac at each multipl...

Focus on data packet loss and time delay problems in wireless greenhouse measurement and control system, and temperature and humidity were taken as the research objects, the model of temperature and humidity information transmission was set up by decoupling technology according to the characteristics of wireless greenhouse measurement and control system. According to related theory of exponenti...

This article first reviews the architecture of a typical ATM switch and considers the problem of handling both continuous bit oriented and bursty traffic with low loss and delay requirements. We examine a buffer architecture that is capable of handling both delay sensitive and loss sensitive traffic, and present a scheme to allocate network resources, i.e. bandwidth and buffer space, to individ...

This paper is concerned with generalized predictive control based on state-space model for networked control systems. Both the network-induced time delay and packet loss are taken into account. The networked predictive controller design is discussed with respect to three network cases, which are related to packet loss, network-induced delay, and both packet loss and network-induced delay, respe...
