The network is equipped with quality of service management, particularly considering multimedia transfers. Thanks to proposed mechanism of guarantees, multimedia data are delivered with guaranteed delay time, not greater than assumed, and in the case the delivery on time is impossible – they are removed, freeing place for remaining packets.
