This paper proposes a feedback-based algorithm for congestion control and bandwidth allocation in the presence of either TCP traffic or both TCP and real-time traffic. In this proposal, the network layer conveys bandwidth and propagation delay measurements to data sources, for instance using IPv6 optional fields. TCP sources use this bandwidthdelay product to control their congestion window, wh...

With the rapid expansion of the Internet, it has become possible for end hosts that are separated long apart to be connected through high bandwidth links. This environment, called a Large Bandwidth Delay Network, poses a major challenge to the performance of the Internet. A long-delay connection usually suffers from being treated unfairly when competing with short-delay connections. A link, to ...

Transmission Control Protocol (TCP) is a connection oriented, reliable delivery, transport layer protocol. The performance of TCP is degraded when it is used in wireless networks. This is mainly because of the basic assumption of TCP that any packet loss is an indication of congestion, which is not true in wireless links. The TCP performance in wireless network can be improved by differentiatin...

This paper presents congestion control mechanisms for reliable and scalable message-oriented middleware following the publish/ subscribe communication model. We identify the key requirements of congestion control in this environment, how it differs from congestion control for the Internet, and propose a combination of two congestion control mechanisms, (1) driven by a publisher hosting broker (...

Real-time media communication requires not only congestion control, but also minimization of queuing delays to provide interactivity. In this work we consider the case of real-time communication between web browsers (WebRTC) and we focus on the interplay of an end-to-end delay-based congestion control algorithm, i.e. the Google congestion control (GCC), with two delay-based AQM algorithms, name...

The application of sliding mode control in wireless network is used for considering the joint congestion control and scheduling. Incorporating dual decomposition enables the joint congestion control and scheduling problem to be considered separately. The communication among these two sub problems is given by the lagrangian price value. Based on the utility optimization of network the congestion...

Broadband satellite-based IP networks have been considered as the technology to enable a strong and promising next-generation market. In satellite communication systems, the channel performance might be severely degraded due to the dynamic weather conditions such as the precipitation, and thereby lead to network congestion. Therefore, congestion control is critical in such networks to satisfy Q...

Congestion control in Signaling System number 7 faces new challenges as mobile communication systems and Intelligent Networks grow rapidly. New services change traffic patterns, add to signalling network load, and raise demands on shorter service completion times. To handle new demands, the congestion control mechanisms must foresee an overload situation, and respond to it so that the network c...

– This paper examines congestion control for explicit rate data networks. The Available Bit Rate (ABR) service category of Asynchronous Transfer Mode (ATM) networks serves as an example system, however the results of this paper are applicable to other explicit rate systems as well. After a plant model is established, an adaptive control strategy is presented. Several algorithm enhancements are ...

This paper presents a discrete-event systems approach to the modeling of a packet-switched communication link shared by multiple users for the purpose of end-to-end congestion control. It introduces a discrete-event system model for the interaction between a shared communication link and the users, which captures the behavior that the link users receive acknowledgments for successfully transmit...
