Congestion control of a variable bit-rate data stream crossing the Internet is crucial to ensuring the quality of the received data. This paper discusses the use of link-sharing mechanisms in packet networks and presents algorithms for hierarchical link-sharing. Hierarchical linksharing allows multiple agencies, protocol families, or traffic types to share the bandwidth on a link in a controlle...

Performance of existing TCP implementations over Optical Burst Switched (OBS) networks is not satisfactory, as they suffer from false congestion detection. As the contention induced losses are more common than congestion induced losses in OBS, the TCP reduces the congestion window even when there is no congestion. This effect, in turn unnecessarily reduces the TCP throughput. So it is crucial t...

Congestion avoidance techniques for event builders using switching network technologies is a major issue. Traffic management of the data flow is an essential point to avoid congestion. Global traffic control is one of the mechanisms to manage the traffic. It uses global information of the switching network. While, traffic shaping technique is another mechanism not to use them. Quality of Servic...

We propose a model and solution methods, for locating a fixed number of multiple-server, congestible common service centers or congestible public facilities. Locations are chosen so to minimize consumers’ congestion (or queuing) and travel costs, considering that all the demand must be served. Customers choose the facilities to which they travel in order to receive service at minimum travel and...
