A method, program and system for transmitting a data stream to a group of recipient nodes from a source node via an intermediate node over a communication network, wherein the data stream is associated with a first unique identifier to identify the content of the data stream. The method includes the source node generating a second identifier, the second identifier distinct from the first unique identifier, and associating the second identifier with the data stream to identify that the data stream is to be received by the group of recipient nodes; transmitting routing information comprising the second identifier to the intermediate node; transmitting the data stream from the source node to the intermediate node; and responsive to receiving the data stream at the intermediate node, reading the second identifier and routing the data stream to the group of recipient nodes in accordance with the routing information.
