A method for establishing a monitoring connection associated to a traffic connection established in a network e.g. of MPLS type, the method comprising the steps of: sending a connection establishment message from a first node (B) to a second node (D) of the communication network to establish a monitoring connection () between the first and second nodes, wherein the first and second nodes are disposed in a path of the traffic connection and the connection establishment message is sent along the traffic connection path,sending a make-before-break request from the first node (B) to an ingress node (A) of the traffic connection to cause the ingress node to re-establish the traffic connection along the traffic connection path using a make-before-break signaling procedure,at the first node, processing a re-establishment signaling message sent by the ingress node so as to encapsulate the re-established traffic connection () into the monitoring connection ().
