摘要
It is disclosed a method for exchanging packets between two nodes of a packet-switched communication network. Each packet comprises a marking field and a reflected marking field. Each node sets the value of the marking field in its outgoing packets to be transmitted to the other node. This value is alternately switched between two alternative marking values every N outgoing packets. While incoming packets are received from the other node, each node also sets the value of the reflected marking field of its outgoing packets according to the value of the marking field of the incoming packets. An observer placed between the two nodes may count the packets whose marking field is equal to any of the marking values and/or the packets whose reflected marking field is equal to any of the marking values, and use N and such counts to provide a packet loss measurement.
