An aspect provides a method of operating a first node (81) in a network, the method comprising receiving (801) a first tunnel request from a second node (82), the first tunnel request comprising an identifier for a target node; assigning (803) a first tunnel identifier to a first tunnel from the second node (82) to the first node (81); sending (805) a first tunnel response to the second node (82), the first tunnel response comprising the first tunnel identifier; sending (807) a second tunnel request to a third node (83) to establish a second tunnel from the first node (81) to the third node (83), the second tunnel request comprising an identifier for a source node and the identifier for the target node; receiving (809) a first communication from the second node (82), the first communication comprising data for the target node and the first tunnel identifier; and sending (811) a second communication to the third node (83) via the second tunnel, the second communication comprising the data for the target node. |
