The present invention concerns a method for dynamic discovery of service functions in an IP network comprising at least one node, called the PDP node, responsible for taking decisions relative to the structuring of a service based on a set of service functions, called SF functions, and for notifying other nodes of said IP network of these decisions, and at least one node, call the SF node, associated with at least one SF function hosted at said SF node or accessible via said SF node. Said method comprises the following steps: the PDP node receives an announcement message sent by the SF node, said announcement message indicating at least one identifier and the location of said SF function associated with this SF node; and the PDP node updates a list of SF functions on the basis of information taken from said announcement message. Application to value added services, for example in an OSPF network. |
