MEASURING NETWORK PERFORMANCE WITH REFERENCE PACKET PROBING

摘要

The present invention relates to a method of measuring network performance. The method comprises the following steps : - Transmitting a payload packet (X) from a sending node (GGSN/A) to a receiving node (GGSN/B) via a communication network (IP). - Transmitting a reference packet (Y) to the receiving node (GGSN/B) in connection with sending of the payload packet (X). - Generating receive information (Tr) related to the payload packet and to the reference packet, at the receiving node (GGSN/B). - Receiving send information (Ts) related to the payload packet and to the reference packet, by the receiving node. - Estimating network performance by utilizing the send and receive information (Ts, Tr;).
