Abstract
A method and system are provided for measuring the bandwidth of a network segment between a first location and a second location by generating a plurality of synthetic packets at the first location and marking each generated synthetic packet with a transmission timestamp indicative of a first clock time at which the synthetic packet is generated; transmitting each of the generated synthetic packets to the second location; receiving each synthetic packet at the second location and marking each received synthetic packet with a reception timestamp indicative of a second clock time at which the synthetic packet is received at the second location; calculating an inter-packet delay variation of the network segment based on the transmission timestamp and the reception timestamp of two or more synthetic packets; and deriving an available bandwidth of the network segment based on the calculated inter-packet delay variation.
