A method for transferring a data message, in a connectionless manner between a selected source terminal and a selected destination terminal, in a communications network which supports connection-oriented communications. The network has a plurality of source and destination terminals in addition to satellites having up and downlink antenna beams. One of the uplink beams covers the selected source terminal and one of the downlink antenna beams covers the selected destination terminal. Downlink beam identifiers are assigned to each downlink antenna beam in the network. An address is assigned to each destination terminal so that the address of the selected destination terminal includes a downlink beam identifier of one downlink antenna beam in the network which covers the selected destination terminal. The downlink beam identifier is used to route the data message through the network.
