The Effect of Bandwidth Management on the Performance of a Window-Based Flow Control

Abstract

In this paper, we derive an algorithm for computing various performance measures for a window-based flow control, subject to bandwidth management. Bandwidth management is a mechanism for maintaining a fair allocation of network resources among customers. We provide an analytic procedure for computing the transmission rate allowed by the window, as well as the throughput of successfully transmitted frames (excluding retransmissions) that the customer can achieve. We will show that, when the network is at a given level of congestion, a customer can choose an appropriate window size to optimize the throughput of successfully transmitted frames, subject to bandwidth management.
