Abstract: A method for enabling a round-trip packet loss measurement between two nodes of a packet-switched communication network exchanging packets comprising a packet loss field settable to an idle value or one or more measurement values. The first node transmits to the second node first packets having the packet loss field set to a measurement value. Upon reception of each first packet, the second node transmits back to the first node a respective second packet having the packet loss field set to a measurement value. Upon reception of each second packet, the first node transmits back to the second node a respective third packet having the packet loss field set to a measurement value. A measurement point placed between the two nodes may count the number of first packets and the number of third packets and use them to provide a round-trip packet loss measurement.
