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

In this paper we analyze the performance of an end-to-end window- based flow control subject to bandwidth management. In particular, we model 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". We explicitly model the effect of frame losses on the performance.
