Abstract

A study on network traffic analysis and modeling has been exclusively done due to its importance. However, conventional studies on network traffic analysis and modeling only focus on transmitting simple packet stream or traffic features of specific application, such as HTTP. In this paper, we propose a network traffic generator, which reflects the characteristics of multimedia data. To analyze the traffics of online game, which is one of the most popular multimedia contents, we modeled the distribution according to the time between packets and packet size random variable and designed the traffic generator which has the model for input. We generated the traffics of L4D(Left4Dead), WoW(World of Warcraft) with proposed network traffic generator and we found that the generated traffics have similar distributions with real data.

네트워크 트래픽 분석 및 모델링은 그 중요성에 따라 많은 연구가 진행되어온 영역이다. 기존의 네트워크 트래픽 분석 및 모델링 관련 연구는 간단한 패킷 스트림을 전송하거나 HTTP와 같은 특정 어플리케이션의 트래픽 특성을 반영하는데 초점이 맞춰져 있다. 본 논문에서는 멀티미디어 데이터의 특성을 반영한 네트워크 트래픽 생성기를 제안한다. 멀티미디어 데이터의 특성을 반영하기 위해 대표적인 멀티미디어 콘텐츠인 온라인 게임의 트래픽을 분석하기 위해서 온라인 게임의 패킷 전송간 시간과 패킷 크기 확률변수들에 따른 분포를 모델링 하였으며 그 모델을 입력으로 갖는 네트워크 트래픽 생성기의 구조를 제시하였다. 제안된 네트워크 트래픽 생성기를 이용하여 L4D(Left4Dead), WoW(World of Warcraft)의 트래픽을 생성해 본 결과 실제 데이터와 유사도가 높은 분포를 갖는 것을 확인 할 수 있었다.
