MODELING AND ANALYSIS OF PERFORMANCE QUALITY INDICATORS OF SINGLE-SERVER SINGLE-CHANNEL MULTI-NODE COMPUTER NETWORKS PROVIDING QUEUE SERVICING WITH FIRST AND SECOND PRIORITY.

This article presents the efficiency of nodes in computer networks with limited queues and absolute priority,serving incoming packet streams.Analysis of a single-channel multi-node network with a limited queue and absolute priority shows that the qualityof service for requests in such networks heavily depends on the load of individual priorities.The provided numerical calculations and proposed graphical dependencies make it possible to determine therequired quality of operation of a specific computer network with a given number of nodes, the number of waitingplaces in specific nodes, and the values of first and second priority loads.A mathematical model of a single-channel multi-node computer network with a limited queue and absolutepriority has been proposed, which makes it possible to determine the quality of functioning of such a network,depending on the number of waiting places in individual nodes and the loads of individual priorities.To ensure the required level of quality of service for requests, it is necessary to increase the number of waitingareas on individual network nodes.Analysis of a single-channel multi-node network with a limited queue andabsolute priority shows that the quality of service for requests in such networks heavily depends on the load ofindividual priorities.
