RESEARCH OF THE PROCESS OF THE FUNCTIONING OF THE ASYNCHRONOUS DATA REPLICATION SYSTEM
The article presents a semi-Markovian model of the functioning of an asynchronous data replication system that processes data on two servers. The residence times of the system in states and their distribution functions are determined, and the probabilities of system transitions are given. There is a stationary distribution of the embedded Markov chain. It is based on the theorem on the average time of the system stay in a subset of states, the server availability factors are found.
