The objective of this work is to analyze the performance of HDLC Balanced Class of
Procedures under saturated, full-duplex transmission on error prone links. This thesis
extends work done by Bux et al.  by considering errors on both the links. Satellite
links have long propogation delays compared to terrestrial links, and hence, have
longer error recovery times. For such links, errors in acknowledgements have considerable
impact on the throughput. In this analysis, the effect of errors in acknowledgements
is taken in to consideration. An analytical approach is used to derive
performance measures. The concept of "virtual transmission time" introduced by Bux
et al is redefined to accommodate the effect of errors in acknowledgements and
used in the analysis. Resulting throughput calculations show how various parameters,
(e.g. transmission rate, propagation delay, error rate and packet size), interact
and determine the performance.
