Patent ID: 7826448

Claim:
Method for setting up a connection between external nodes (Nj) connected to a communication network with Generalized Multiprotocol Label Switching (GMPLS) control plane (RG) and each comprising a portion (PAj) of a distributed application and a signaling module (MSj) configured to manage the setting up of connections, comprising the steps of: i) when a connection between a first (N 1 ) and a second (N 2 ) external nodes must be set up, generating in the first external node (N 1 ), by means of a communication service session protocol, a first message requesting the setting up of a connection session and comprising parameters defining a connection to be set up, then transmitting the first message from the first external node towards the second external node (N 2 ), via said network (RG), ii) in a point of said network (RG), detecting each such first message in a communication service session and analyzing the first message in order to convert the parameters which it contains for the GMPLS control plane and to check their compatibility with another application resident in the network and with the GMPLS control plane, iii) if the parameters are compatible, sending said first message in said network (RG) from said point of said network, by means of the communication service session protocol, transmitting it to said second external node (N 2 ), iv) on receipt of said first message in said second external node (N 2 ), determining at the second external node whether the connection parameters which it contains are supported by at least one of the portion of the distributed application (PA 2 ) of the second external node and the signaling module (MS 2 ) of the second external node, and v) if the connection parameters are supported, transmitting from the second external node a second message for authorizing the setting up of a session, to said first external node (N 1 ), via said network by means of the communication service session protocol, in order that the signaling module (MS 1 ) of the first external node shall initiate the setting up of said connection.
