A method for diagnosing service functions in an IP domain including a PDP node, which makes decisions relating to structuring of a service function chain relying on a set of service functions (SF), and notifies these decisions to other nodes of the IP domain, and at least one SF node associated with at least one SF function hosted by or accessible via the SF node. The method includes: a diagnosing node sending a request to an SF node (a diagnosed node) concerning a diagnosed SF function, which is identified in the request and/or is the only SF function associated with the diagnosed node; the diagnosed node forms at least one diagnostic operation concerning the diagnosed function; and the diagnosed node sends a response to the diagnosing node, the response including an indication of success or failure of the diagnostic operation or of non-operation or malfunction of the diagnosed function. |
