Abstract: An intermediary node (105) comprises a first control node communication module (151) adapted for forming a first communication network (152) with a first control node (101); a second control node communication module (153) adapted for forming a second communication network (154) with a second control node (103), wherein the first communication network is communicatively separated from the second communication network; and a user node communication module (155) adapted for forming a user communication network (127) with at least one first user node (109) and for receiving a user request (141) from the first user node, wherein the intermediary node (105) is adapted to generate an anonymous user request (143) based on the user request and to perform a selection to transmit the anonymous user request selectively to the first control node (101) or to the second control node (103).

Abstract: A communication network comprises a first control node (101) and at least one second control node (103), wherein the first control node and the second control node form a first-level communication network (113) which communicatively couples the first control node to the second control node, wherein the first control node comprises a first intermediary node communication module (123) for forming a first second-level communication network (121) between the first control node (101) and a first intermediary node (105), wherein the first intermediary node communication module is adapted to receive an anonymous request (143) from the first intermediary node (105), the anonymous request (143) being based on a first user request (141) transmitted from a first user node (109) to the first intermediary node (105), wherein the first control node (101) is adapted to transmit the anonymous request (143) to the second control node (103).
