INTERNET FLOW DATA ANALYSIS METHOD USING PARALLEL COMPUTATIONS

A method of analyzing internet flow data includes: (A) an internet flow data input step of dividing internet flow data stored in a file system and receiving the divided data at one or more data nodes; (B) a Map task step of producing, with respect to each of the data nodes, a (Key, Value) pair from the received data and temporarily storing the (Key, Value) pair; and (C) a Reduce task step of calculating a (Key, SUM(Value)) value from the stored (Key, Value) value and storing the calculated (Key, SUM(Value)) value. In accordance with the method, the analysis task is not performed in one server, but distributed into a plurality of server and then performed. Accordingly, internet flow data can be analyzed within a shorter period.
