Redundant Maintenance of a Non-Uniform Query Stream by a Sequence of Nodes that are Grouped Together in Groups

The possibilities of improving the efficiency of reserved service for a non-uniform query flow with a sequence of nodes of an info-communication system that are combined into groups are investigated. It shows the possibility of reducing the average total waiting time for requests that are critical to delays and the effectiveness of reserved query service, in which the request is received at each level is accompanied by the formation of a specified number of copies of it with their distribution among the reserved nodes of the corresponding level. The first copy of the request is sent to the next level of the system for reserved maintenance, and the remaining copies are destroyed.
