Recently, the technological capability of developing virtual private networ
ks in open systems has emerged. To ensure their system safety, we propose a
method for their restructuring in the process of exploitation. The problem
of redistribution of queries in the channels connecting the servers emerge
d. To solve this problem, a mathematical model of parallelizing the process
of interaction of servers connected by a virtual ring with the correspondi
ng star/ring structure is proposed in the article.
