Design and evaluation of an adaptive flow control scheme

The authors model a virtual circuit in a computer network as a sequence of servers in tandem. They explicitly take into account cross traffic at the servers from other virtual circuits. The analysis of the model leads them to propose a novel flow control scheme, which they term send-time control. A measure to evaluate the performance of flow control schemes, called the packet performance index, is proposed. They compare the send-time control scheme with the window-based flow control scheme of transmission control protocol (TCP) using simulation. The results obtained show that send-time control is superior to the window-based scheme
