摘要
Variation in delay in transmission of data from a transmitting station to a receiving station is measured by encapsulating a portion of the data and an outgoing time stamp in a packet, the outgoing time stamp substantially representing the degree of progression of a periodic process at the time of including the outgoing time stamp in the packet. The packet is transmitted from the transmitting station and is received at the receiving station. At the receiving station, an incoming time stamp is added to the packet. The incoming time stamp substantially represents the degree of progression of a periodic process at the time of adding the incoming time stamp to the packet. The incoming time stamp is compared to the outgoing time stamp.
