METHOD FOR MEASURING NETWORK PERFORMANCE USING INTERMEDIATE MEASUREMENT NODES

摘要

The present invention relates to methods and arrangements to measure network performance, wherein a send specification (Sx;Sp) for each of at least one probe packet (X;P) is generated at a sending node (GGSN/A; GW/A). The probe packet is transmitted from the sending node on a communication path (A-D) in a communication network (IP; ETHERNET), towards a receiving node (GGSN/B; GW/B). The method comprises the following steps: - The probe packet (X;P) passes at least one intermediate measurement capable node (IMEN1-IMEN3) located on the path (A-D) between the sending node and the receiving node. - At least one time stamp specification (rx1-rx3, sx1-sx3; rp1-rp3, sp1-sp3) for the packet (X;P) is generated at the intermediate measurement capable node (IMEN1-IMEN3). - the probe packet is received by the receiving node (GGSN/B; GW/B) and a receive specification (Rx;Rp) is generated for the probe packet. - Network performance is estimated by utilizing generated specifications (Sx, rx1-rx3, sx1-sx3, Rx; Sp, rp1-rp3, sp1-sp3, Rp).
