Packets may be routed in a heterogeneous communications network as follows: for a set of packets comprising at least one packet to be transmitted from a sending node, said sending node being able to handle communication according to at least two access technologies, —selecting in a selection unit in the sending node an access technology for use when transmitting the set of packets, —selecting a receiving node in the network to which to transmit the set of packets among nodes in the network that are able to handle said selected access technology—transmitting the set of packets to the selected receiving node using the selected access technology. Alternatively, a set of packets may be transmitted to one or more nodes using at least two different access technologies. Depending on the transmission quality, one node may be selected to forward the set of packets.
