Flow Data Analyze Method by Parallel Computation

摘要

The present invention relates to a flow data analysis method, and more particularly, (A) flow data input step of dividing the flow data stored in the file system in the manager node to one or more data nodes; (B) a map operation step of generating and temporarily storing a (Key, Value) pair from data input at each data node; And (C) a reduce operation step of calculating and storing a (Key, SUM (Value)) value in the data node from the (Key, Value) value stored in the map operation step. It relates to a flow data analysis method for monitoring network traffic, characterized in that the parallel operation by the method). According to the flow data analysis method of the present invention, when performing a traffic data-based traffic analysis in the traffic monitoring equipment, the analysis work previously performed in one server can be distributed to multiple servers and processed in parallel, so that the shortest time You can analyze the flow data in the and send the result to the user.
