In a previous research work an enhanced HDLC link protocol with dual windows was developed and and evaluated (by simulation). It was shown that this approach is superior to a method which just increases the window size. Most time-outs and forced half-duplex operation periods are avoided which make this new protocol version of HDLC particularly suitable for harsh error environments and large bandwidth x rate terms. For this research the theoretical protocol scheme is to be implemented with HDLC as implementation example. Test runs in a error-prone point-to-point environment are to be performed and the actual performance is to be compared to the one previously obtained by computer simulation. Based on a statistical model of the error environment, an analytical derivation of the protocol efficiency, and thus of the performance, is also to be found. Participating in this research and development work are Dr. Bernd J. Kurz (Professor) with the assistance of Syed Zeeshan Hasnain, undergraduate Honours student.
