Reliable Link Initialization Procedures

Abstract

It is known that HDLC 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. We show in this paper that the HDLC initialization procedure does not ensure synchronization and allows inadvertent loss of data. We then propose several new link initialization procedures and prove that they do ensure synchronization. © 1988 IEEE
