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.
Data on the evaluation of the channel resource of the aggregated data flow for the protected information transmission channel of the special purpose information communication network are provided. It is shown that an increase in the load on a protected data transmission channel causes an increase in the required 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 and the type of traffic. The use of the isolated service method gives a gain in the necessary channel resource from 10 to 20 percent compared to the group service method for IP telephony and up to 25 percent for Video telephony.
It was established that with an increased load of the aggregated data flow on the protected channel, the necessary delay in the processing of data packets is not provided within the established regulatory values. When aggregated data flows are served in a protected channel, the type of data traffic is important. For the aggregated data flow of encrypted Video-telephony, the specified level of the necessary delay in the processing of data packets is ensured by exceeding the reserved resource of the peak value of the transmission speed.
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.
