Abstract: In a method for measurement of a round-trip performance in a packet-switched communication network, a measurement device cooperating with the communication network generates a flow of test packets formatted according to the network protocol supported by the network and comprising the address of the measurement device as destination address. The test packets are then transmitted within a tunnel set up in the network and the measurement device generates one or more transmission parameters. At the end of the tunnel, the test packets are extracted therefrom and sent back to the measurement device by the forwarding function of the network protocol supported by the network. Upon receipt of the test packets, it generates one or more reception parameters, which are then combined with the transmission parameters to provide the round-trip performance measurement.

Abstract: It is disclosed a method for performing a performance measurement on a packet flow transmitted through a packet-switched communication network. In the packet flow, first blocks of packets having a first packet feature and second blocks of packets having a second packet feature are provided by periodically switching a packet feature in the packet flow, so that the first blocks of packets alternate in time with the second blocks of packets. Two or more measurement points on the path of the packet flow provide performance parameters relating to the first and second blocks of packets, and alternately provide their values to a network controller, which the controller uses to perform the performance measurement. The periodic switching of the packet feature and the alternate provision of the performance parameter values are in response to remote commands received from the controller.
