摘要: A network monitoring and congestion analysis can be performed based on a comparison of data packets at multiple different nodes installed locations communication path. downstream node may user location while an upstream access router further up the network. analyzer receive packet information including timestamps from both nodes, compare to group into application flows match corresponding nodes. Based matching, calculate loss, delay, delay variation, perform other techniques for user's various devices applications executing those devices.
