A first data packet is sent through a system under measurement (SUM) from a sender side to a receiver side. A time distance d between the first data packet and a second data packet consecutive thereto in a packet flow is observed on the sender side. A value of d is written into a payload of the second data packet. The second data packet is sent through the SUM. The first data packet and the second data packet are received on the receiver side. A time difference D between the first data packet and the second data packet is observed on the receiver side. The value of d is extracted, at the receiver side, from the payload of the second data packet. The jitter is determined based on the value of d extracted from the payload of the second data packet and the value of the time difference D.
