Abstract

Wireless Internet is the network which provides wireless access in order to serve the Internet connections and data communication through the mobile handsets. To get efficient wireless access to the Internet, we need the WAP (Wireless Application Protocol) gateway that performs protocol translation and contents conversion between two different networks. We need the capacity dimensioning of the WAP gateway system in order to provide the wireless Internet service stably and cost-effectively. We also need the traffic engineering methods including traffic modelling and forecasting for the economical facility investment. The existing method of WAP gateway capacity dimensioning was intuitive and qualitative. But in this paper, we deal with the capacity dimensioning analytically and quantitatively on the basis of WAP traffic description parameters and traffic forecasting method.

무선인터넷은 이동 단말기를 통해 무선으로 인터넷에 접속하여 데이터 통신이나 인터넷 서비스를 제공받을 수 있는 네트워크이다. 무선 접속망과 유선 인터넷의 다른 두 네트워크를 효율적으로 연동하기 위해서는 프로토콜 전환 시스템인 WAP게이트웨이가 필요하다. 무선인터넷 서비스를 안정적이고 비용 효율적으로 제공하기 위해서는 적절한 게이트웨이 시스템 용량산출이 필요하고 시설투자의 경제성을 획득하기 위해서는 트래픽 모델링 및 예측을 포함한 트래픽 엔지니어링 기법이 필요하다. 기존의 용량산출 기법은 직관적이고 정성적인 방식을 탈피하지 못했으나 본 논문에서는 보다 정량적이며 해석적으로 WAP 서비스에서 트래픽 기술 파라미터 정의하고 트래픽 예측 기법에 근거한 용량산출 기법을 다룬다.
