Rate-based flow control mechanisms have been widely deployed in real-time multimedia applications over best-effort networks due to its short propagation delay. In this paper, based on the feedback control of buffer occupancy (BO), a new rate-based flow control mechanism is proposed. Feedback control ideas have been used successfully in computer systems to control the uncertainty of complex and ...

In this paper we introduce a real time congestion control mechanism to multicast the multimedia applications. The key challenge in the design of this mechanism is to calculate the rate of feedback messages by various receivers; appropriate feed back suppression, scalable round trip time measurements & ensuring that feedback delays in the control loop do not adversely affect fairness towards com...

In positive feedback mechanisms, the response to a stimulus does not stop or reverse it but instead keeps the sequence of events going up. At first glance, this would appear to be a counter to the principle of homeostasis, since a positive feedback loop has no obvious means of stopping. Not surprisingly, therefore, the positive feedback is less common in nature than the negative one. A positive...
