Claim:
1. A method for performing a performance measurement of a link connecting a first node and a second node of a communication network, the method comprising: a) before starting a performance measurement, providing the first node and the second node with measurement mode information comprising at least a measurement start time and a packet transmission rate; b) at the measurement start time, generating and transmitting a packet flow from the first node to the second node, the packet flow comprising a plurality of packets whose transmission times are determined by the measurement start time and the packet transmission rate, the generating and transmitting comprising generating and transmitting first packets during first block periods and second packets during second block periods which alternate in time with the first block periods; c) at a block period of the first block periods or second block periods, while the packet flow is received at the second node, updating a variable indicative of a behaviour of the packet flow during the block period, by using the measurement mode information and detected information on reception of the packet flow; and d) at a subsequent block period of the first block periods or second block periods, calculating a parameter indicative of a performance of the packet flow during the block period using a value reached by the variable at the end of the block period.
