Decomposition task of the IPDV value established for the next generation network

This article considers a decomposition problem of the IPDV index that defines variation of packet delay in the next generation network. A model of packet connection between user-network interfaces as a multistage queuing system is proposed. For this model, equations have been derived that allow to decompose the studied index on different stages depending on their number and level of load. An accuracy of proposed method for decomposition of packet delay variation in the next generation network has been estimated.
