Flow model for multipath routing with
guaranteed the quality of service (QoS) is proposed. The
model is based on the updated version of flow conservation
law, which is taking into account the possible packet loss
caused by buffer overflow at the network routers. The
accounting such losses is related to revise conditions
associated with the quality of service. By using tensor
approach analytical boundary conditions were obtained.
The conditions allow ensuring different parameters of the
quality of service (rate, average delay and packet loss
probability) at the same time. In addition, proposed model
provides minimal value of average end-to-end packet delay
where delays along all paths are same. As a result jitter
caused by the multipath routing (difference between delays
along different paths) is minimized. The developed
conditions for QoS ensuring have invariant form which do
not depend on the used at the interface. Changing the
traffic models and/or packet servicing algorithm is related
to a modification of the metric only within the same form of
conditions.
