Abstract

Internet traffic has rapidly increased due to the supplying wireless devices and the appearance of various applications and services. By increasing internet traffic rapidly, the need of Internet traffic classification becomes important for the effective use of network resource. However, the traffic classification scheme is not much studied comparing to the study for classification method. This paper proposes novel classification scheme for multilateral and hierarchical traffic identification. The proposed scheme can support multilateral identification with 4 classification criteria such as service, application, protocol, and function. In addition, the proposed scheme can support hierarchical analysis based on roll-up and drill-down operation. We prove the applicability and advantages of the proposed scheme by applying it to real campus network traffic.

인터넷을 기반으로 하는 다양한 서비스 및 응용의 등장과 무선 디바이스의 보급은 인터넷 트래픽을 급격하게 증가시켰다. 인터넷 트래픽의 급격한 증가로 한정적인 네트워크 자원을 효율적으로 사용하기 위해 인터넷 트래픽 분석의 중요성이 증가하고 있다. 하지만 트래픽 분석 방법론에 비해 분석 결과를 체계적으로 관리하는 분류 체계에 대한 연구는 이루어지지 않고 있다. 본 논문에서는 다각적이고 계층적인 트래픽 분석을 위한 분류 체계를 제안한다. 제안하는 분류 체계는 서비스, 응용, 프로토콜, 기준의 4가지 분류 기준을 사용하여 다각적으로 분석이 가능하며, 분류 기준 별로 계층화된 속성을 가지고 있어 결과의 통합화 및 세분화가 가능하다. 논문에서는 제안한 분류 기준을 실제 학내 망에 적용하여 분석함으로 분류 체계의 장점과 활용성을 보인다.
