The paper deals with the problem of ensuring the network service quality by using multipath routing protocols by splitting the application data flow to several subflows, each of which is transmitted through its own route in the network. There are two classes of multipath protocols: the static one with fixed number of subflows during the connection lifetime and the dynamic one which varies the number of subflows depending on the current network state and application requirements. The paper presents the comparative analysis of the effectiveness of static and dynamic multipath transport protocols. The comparison methodology is invariant to the network topologies, load, and transport agent settings. The areas of static and dynamic multipath protocol efficiency are derived based on study results. The experimental study has shown the advantage of a dynamic approach.
