A communication device (S) for an MPLS network comprises a signaling module capable of establishing a point-to-multipoint MPLS connection tree with a plurality of leaf nodes (A, B) by transmitting a connection request message and by receiving a reservation method in response, said connection request message comprising addresses of said leaf nodes and characteristics of downstream traffic in order to characterize the quality of service desired for a downstream data flow to transmit to said leaf nodes, said reservation message comprising a label for establishing a downstream MPLS connection. To bidirectionally establish the MPLS connection tree (15, 16, 17), the connection request message further comprises characteristics of upstream traffic in order in order to characterize the quality of service desired for upstream data flows to be received from said leaf nodes and a label for establishing an upstream MPLS connection.
