Throughput Analysis of an Adaptive Window-Based Flow Control Subject to Bandwidth Management

In this paper we analyze the performance of an adaptive end- to-end window-based flow control subject to bandwidth management (BWM). We start with an analysis of an HDLC type layer 2 protocol based on positive acknowledgements for correctly received frames. The LAPD protocol is currently under consideration by standards bodies for use in frame transport via end-to-end "frame relay" [1]. We explicitly model the effect of frame losses on the performance.
