MODEL FOR CALCULATING THE CHANNEL RESOURCE OF AN AGGREGATE DATA FLOW OF A SECURE INFORMATION TRANSMISSION CHANNEL OF A SPECIAL-PURPOSE INFOCOMMUNICATION NETWORK

Abstract

In the article, a new topical scientific task is solved regarding the evaluation of the channel resource of the aggregated data flow for the protected information transmission channel of the special purpose information communication network.

A model for calculating the channel resource of the aggregated data flow of a special purpose information communication network has been developed and presented. The presented model makes it possible to obtain quantitative values of the channel resource for various methods of service depending on the load of the aggregated flow of the protected channel of the special purpose information communication network. The difference of the model is the ability to make calculations taking into account the quality criterion of data transmission channel service depending on the selected method of data flow maintenance of the protected information transmission channel.

It is shown that the growth of the load on the protected data transmission channel increases the necessary channel resource. At the same time, the required value of the channel resource depends on the method of servicing the aggregated data flow in the protected channel of the special purpose information communication network. The use of the isolated service method gives a gain in the required channel resource of 10 to 20 percent compared to the group service method for IP telephony.

The presented results can be applied in the development of new and improved existing telecommunication systems intended for the transmission of confidential information through secure channels.
