A method for sending a data packet, which directly or indirectly indicates a quality-of-service requirement, to a mobile node from a correspondent node via a multi-bearer network, or MBN, that provides at least one interface unit to each of multiple alternative bearer networks between the MBN and the mobile node includes, in one embodiment, selecting an optimal bearer network for sending a data packet between the MBN and the mobile node based on the quality-of-service requirement of the data packet in question; traffic load data related to the multiple bearers; interface unit availability information; and bearer type preference information.
