Measurement of Network Performance in Transporting Packet Streams

摘要

A method and apparatus for measuring network performance. A packet from a stream of multimedia data packets is received from across a network during a measurement interval. The time interval from the start of the measurement interval to receiving the packet is measured. The response of a buffer to the received packet is determined. The level of the buffer just before the packet arrives is calculated, based on the time interval. The level of the buffer just after the packet arrives is calculated, based on the previous level. A performance measure for the network is determined based on at least one of the two levels.
