This article studies the loss process in Internet Protocol (IP) networks. Obtaining information about network loss patterns is important for measuring network performance during multimedia traffic. To analyze the packet loss process, specific information was collected about when a loss occurs in the network, which packets are lost, whether the loss clusters into packets (episodes), the duration of the loss episodes, and what was the impact of network protocols on the loss. The main result of the work is a series of measurements in order to find out the mutual influence of information flows between interfaces on the value of the loss probability of a single stream, as well as to find out whether there will be any dependence on packet losses. This article includes 16 pages, 6 figures and 9 references.
