Method of selecting a network resource

A method of selecting a network resource, the method comprising:

• a controller device receiving from a controlled-entity device in an Internet Protocol (IP) network a first session control signal, which contains information specifying that the controlled-entity device is capable of selecting network resources among existing physical or virtual network resources by taking into account received transport plane resource identifiers;
• the controller device intercepting in the IP network a request sent or relayed by a controlled-entity device or sent to the controlled-entity device, wherein said request does not recommend that any resource, among said IP network and another physical or virtual network, be used by the controlled-entity device in order to satisfy said request;
• and
• after receiving the first session control signal from the controlled-entity device and intercepting the request, a step of said controller device sending to the controlled-entity device a second session control signal containing a transport plane resource identifier representative of said IP network or of some other physical or virtual network that the controlled-entity device is recommended or required to use in order to satisfy said request.

• interpreting a transport plane resource identifier contained in said received second session control signal and representative of the IP network or of said other physical or virtual network that the controlled-entity device is recommended or required to use in order to satisfy said request;
• and
• setting up a session corresponding to the received second session control signal by selecting a network resource either in the IP network, or in the other physical or virtual network, in the transport plane, by taking into account the transport plane resource identifier received with the second session control signal.

• said controlled-entity device sends a first session control signal to the IP network, which contains information specifying that the controlled-entity device is capable of selecting network resources among existing physical or virtual network resources by taking into account received transport plane resource identifiers;
• sending or relaying a request by said controlled-entity device in said IP network or is sent to said controlled-entity device, wherein said request does not recommend that any resource, among the IP network and said other physical or virtual network, be used by the controlled-entity device in order to satisfy said request;
• after sending the first session control signal and sending or relaying the request, the controlled-entity device receiving via the IP network a second session control signal, in response to the request, containing a transport plane resource identifier representative of the IP network or of said other physical or virtual network that the controlled-entity device is recommended or required to use in order to satisfy said request;
• and
• after receiving the second session control signal containing the transport plane resource identifier, a step of the controlled-entity device setting-up a session corresponding to the received second session control signal by selecting a network resource either in the IP network, or in the other physical or virtual network, in the transport plane, by taking into account the transport plane resource identifier received with the second session control signal.
