Abstract

A network traffic analyzing device, method and system are provided that reliably analyze network traffic with high precision, and reliably analyze alert generation cause. The network traffic analyzing device accurately analyzes traffic of a communications network. The traffic analysis device includes a real time monitoring unit configured to collect information regarding communication data between a primary network and an access network from a traffic collecting device in real time; an alert managing/notifying unit that generates an alert regarding traffic between the primary network and the access network based on the information collected in real time by the traffic collecting device; and an alert generation cause analyzing unit that analyzes a cause of the alert generated by the alert managing/notifying unit based on information regarding at least one of normal data and abnormal data transmitted and received between the primary network and the access network prior to generation of the alert by the alert managing/notifying unit.

Description

technical field [0001] The invention relates to a traffic analysis device, a traffic analysis method and a traffic analysis system. Background technique [0002] Conventionally, as a method of analyzing traffic on a line, a method of extracting traffic data collected by a traffic collecting device and entrusting a professional technician to perform traffic analysis is known. Furthermore, there is known a method in which the traffic data collected by the traffic collection device is directly converted into a count table or a waveform, and the administrator analyzes the waveform based on these waveforms. [0003] [Patent Document 1] Japanese Patent Laid-Open No. 2007-006477 [0004] However, in the prior art mentioned above, when there is a problem in the communication traffic, the manager needs to collect information (data) through manual operation. Explain why. On the other hand, even when the information can be collected, there is a problem in that a large amount of info...
