A communication device (B) for a communication network with an IP control plane, comprises communication resources to transfer data in said network, a signalling controller capable of receiving an open connection message comprising a first traffic descriptor (11) for a down data flow to be transmitted by an initiator node (A) to a terminator node (C) and a second traffic descriptor (12) for an up data flow to be transmitted by the terminator node from the initiator node, and an admission controller capable of evaluating communication resources of the communication device available for said down flow and said up flow as a function of the first and second traffic descriptors, said signalling controller being capable of producing an updated open connection message as a function of said received open connection message and said available communication resources.
