Reliable link initialization procedures

It is known that HDLC (high-level data link control) and other bit-oriented DLC procedures ensure data transmission reliability across noisy transmission media, provided that all frame errors are detected and the link processes are synchronized at initialization. It is shown that the HDLC initialization procedure does not ensure synchronization and allows inadvertent loss of data. Several link initialization procedures are proposed and it is proved that they do ensure synchronization.<
