Executive Summary

In this paper correspondence between experimental data for packet delay and two theoretical types of distribution is investigated. Calculations have shown that the exponential distribution describes the data on network delay better, than truncated normal distribution. Precision experimental data to within microseconds are gathered by means of the RIPE Test Box. In addition to exact measurements the data gathered by means of the utility ping has been parsed that has not changed the main result. As a result, the equation for an exponential distribution, in the best way describing process of packet delay in a TCP/IP based network is written. The search algorithm for key parameters as for normal, and an exponential distribution is resulted.
