Abstract: PURPOSE: A flow data analysis method by parallel operation is provided to distribute flow data to a plurality of servers and to analyze the flow data in the server. CONSTITUTION: A manager node reads flow data stored in a file system from the first line of the flow data, and assigns and inputs the flow data to one or more data nodes(101). The data node is composed of one or more servers. The data node creates a (Key, Value) pair from data inputted from each data node and temporarily stores the pair(102). The data node reads the pair stored in a temporary storage and creates a result by flow data(103).

Abstract: PURPOSE: A method and an apparatus for decoding Korean or Japanese strings in HTTP packets, and a method for analyzing web contents using the same are provided to compare Korean and Japanese strings with a complete Korean code value when the Korean and Japanese strings encoded in the HTTP packets are detected and decoded, thereby outputting Korean or Japanese characters corresponding to the complete Korean code value. CONSTITUTION: When a packet is an HTTP(Hypertext Transfer Protocol) response packet and a packet capable of decoding Korean and Japanese, a flow table for the packet is generated. A payload part of the packet is saved. When the packet is the last packet of a flow, the flow table is initialized. When the packet is not the last packet of the flow, the flow table is updated. In case of a compressed packet, compression of a payload of a flow is decompressed and Korean or Japanese is decoded from a string of an HTTP payload of the flow.

Abstract: 본발명은플로우데이터분석방법에관한것으로, 보다상세하게는 (A) 메니져노드에서파일시스템에저장되어있는플로우데이터를분할하여한 개이상의데이터노드로분배하는플로우데이터입력단계; (B) 각각의데이터노드에서입력된데이터로부터 (Key, Value) 쌍을생성하고임시저장하는맵 작업단계; 및 (C) 맵작업단계에서저장된 (Key, Value) 값으로부터데이터노드에서 (Key, SUM(Value))값을계산하여저장하는리듀스작업단계;로이루어지는맵(Map)-리듀스(Reduce) 방법에의해병렬연산하는것을특징으로하는네트워크트래픽모니터링을위한플로우데이터분석방법에관한것이다. 본발명의플로우데이터분석방법에의하면트래픽모니터링장비에서플로우데이터기반의트래픽분석작업을수행할때 기존에하나의서버에서이루어지던분석작업을다수의서버에분산하여병렬로처리할수 있으므로, 최단시간에 Flow Data를분석하여그 결과를사용자에게전달할수 있다.
