Abstract
In view that some international bodies in the field of Telecontrol systems propose reliability requirements for line protocols which are not fulfilled by standard HDLC,here a detailed analysis of the reliability of HDLC is given and the statistical properties of sequences using the Bit Insertion Mechanism are analyzed. The final result is a proposal of a method,the Four Redundancy Bit Sequence method: (FRBS),which seems able to be added without much trouble before and after the HDLC layer to yield a protocol with the desired characteristics.

Computing Reliability Intervals for k-Resilient Protocols
k-resilient protocols are used in some parallel and distributed system applications for increased availability of resources. A protocol running on an n site system is k resilient if it could tolerate up to k failures and operate correctly. The ...
