Current packet networks use a large variety of mechanisms which should support QoS (Quality of Service). One of those mechanisms is routing (calculating connection paths for incoming service requests). The most effective mechanism in QoS context is dynamic routing, which is based on the current network state described by the offered traffic matrix and link states. After switching between calculated available paths, connection path changes may cause received packets to change order within a single stream. This paper includes problem definition and the analysis of all additional effects. Combined model simulation/analytic was proposed in order to answer whether the number of changed packet order is significant and if it should be considered when calculating the end-to-end delay balance in analytical models for packet networks with differentiated services. Furthermore, the proposed model gave the answer how often calculated paths may be switched to avoid network beingout of tune.
