The present invention relates to methods and devices for monitoring a data path extending from an originating node to a terminating node in a network. In a first aspect of the present invention, the method comprises the step of submitting, to the originating node, a request to monitor at least one network status parameter associated with a particular data flow transported on the data path. Further, the method comprises the step of submitting, to all nodes in the data path, a data flow identifier indicating the particular data flow being one out of a plurality of data flows that can be transported on the data path. Moreover, the method comprises the step of receiving, from at least one of the nodes in the data path, a response message comprising the requested at least one network status parameter.
