Annotation

The paper describes the results of implementation of the simulation model of service

processes developed by the author describing the total non-uniform flow of messages of the

operational, reference and routine information by the computer network node. Experiments

with the simulation model are carried out for different values of the loading factors of the

node of the computer network, as well as at different levels of priority in servicing

communications operational, reference and regulatory information. Recommendations on

the application of service priority levels for streaming messages of operational, reference

and routine information are formulated, depending on the intensity of receipt of these

messages and the duration of their service by the computer network node.

Keywords: information flows, mass service system, priority of service, probability distribution laws, simulation model.
