Method For Calculating Statistic Data of Traffic Flows in Data Network And Probe Thereof

摘要

The disclosure provides a probe and a method for calculating statistic data of traffic flows. The probe comprises at least one link processor (LP) and a correlation processor (CP). Each LP includes two buffers, receives packets from directional traffic flows, generates information of bi-directional traffic flows based on the received packets, stores the generated information in one buffer within a reporting period and, reports the stored information to CP when the reporting period boundary is reached. The information of each bi-directional traffic flow includes the relevant identification information and statistic data. The CP calculates statistic data of a particular group of traffic flows with a predetermined characteristic based on the reported information, and the other buffer stores information of bi-directional traffic flows to be generated within a next reporting period and the stored information is to be reported to the correlation processor when the next reporting period boundary is reached.

1. A probe comprising:
at least one link processor and a correlation processor connected thereto, wherein each of the at least one link processor includes two buffers, and each link processor receives a plurality of packets from a plurality of directional traffic flows, generates information of a plurality of bi-directional traffic flows based on the received packets, stores the generated information in one of the two buffers within a reporting period, and reports the information stored in the one of the two buffers to the correlation processor when the reporting period boundary is reached, wherein the information of each of the bi-directional traffic flows includes identification information extracted from received packets related to each of the bi-directional traffic flows, and statistic data accumulated based on the received packets related to the each of the bi-directional traffic flows, wherein the correlation processor calculates statistic data of a particular group of traffic flows associated with a predetermined characteristic, based on the reported information of bi-directional traffic flows corresponding to the particular group of traffic flows, and wherein the other of the two buffers stores information of bi-directional traffic flows which is to be generated within a next reporting period and reports the stored information in the other of the two buffers to the correlation processor when the next reporting period boundary is reached.
