BUILDING OF A GEOGRAPHICALLY DISTRIBUTED COMPUTER SYSTEM AND ASSESSMENT OF ITS RELIABILITY

This article describes the approach to the design of a geographically distributed system, which allows you to increase the resiliency of each independent network infrastructure, minimizing the probability of data loss in a complete system. The purpose of the research is to develop algorithms and mechanisms that allow replication of each node of the network infrastructure, as well as intelligently determine the situation in which each independent link in the system goes into a critical state. When a critical state occurs, that is, a state in which the system link loses its operation, a backup link is put into operation. In the model used, it is proposed to increase the resiliency of a geographically distributed system whereby each of the links acts as an independent unit of a computer system. As a result of the work, an analysis was made of various options for connecting the system, considering the probability of failure of each of the independent links.
