Active queue management (AQM) mechanism plays an important role in network congestion control. In this paper, we propose an effective AQM algorithm, named adaptive real queue control (ARQC). In particular, an explicit congestion indicator, virtual regulating time, is designed to detect network congestion. Then by analyzing the queuing system on routers, we present the guideline to calculate the dropping/marking...
Recently time-delayed dual model has attracted great attention in studying Internet congestion control. Stability analysis of time-delayed dual model is an important task, where how to determine its solution is the first step. Usually perturbation method can be used to seek the solution of the model, however, its effectiveness depends on a small parameter and it will be invalid when such a parameter...
Peer-to-peer file sharing applications, which enable peers to establish multiple TCP connections between other peers to transfer data, pose new challenge to congestion control. Since conventional congestion control only aims to make each of those connections TCP-friendly, self users can increase the number of connections to grab a large share of the bandwidth, introducing more congestion and degrading...
Multimedia streaming over the Internet has been a very challenging issue due to the dynamic uncertain nature of the channels. This paper proposes an algorithm for the joint design of source rate control and congestion control for video streaming over the Internet. With the incorporation of a virtual network buffer management mechanism (VB), the quality of service (QoS) requirements of the application...
