This paper analyzes the reasons of appearance of non - Byzantine and Byzantine fault types in redundant computer systems. The proposed approach is based on analysis of the relationship between the modes of intercomputer communications and fault types. This analysis allows the users to design the redundant computer systems in such a way that Byzantine faults cannot appear. Consequently, designing the redundant computer systems, in which Byzantine faults cannot appear, allows the designers to increase the degree of reliability by preventing the masking of any forms of appearance of faults and by decreasing the time period of checkpoints. In addition, this approach decreases the cost of software and hardware involved in the execution of fault-tolerant procedures.
