초록

본 논문에서는 IP 기반 무선 인터넷 접속망 환경에서 효율적인 패킷 전달 방법을 제안한다. 패킷 전달은 연결형 (connection-oriented) 기반으로 패킷 전달 이전에 구성된 플로우(flow)에 따라 이루어진다. 이를 위하여, 무선 인터넷 접속망에서의 플로우 구성 방법과 패킷 전달을 위한 변형된 IPv6 (modified-IPv6) 헤더를 정의하였다. 또한, 무선 단말의 이동성을 지원하기 위한 방안과 제안한 방법의 구현 방안을 설명하였다. 제안 방법의 성능 분석을 위하여, 무선 인터넷 접속망에서의 패킷 전달 지연 시간을 분석하였다. 수치 해석을 통한 성능 분석 결과는 제안 방법이 매우 효율적임을 보여준다.

In this paper, we propose an efficient packet forwarding method for an IP-based wireless Internet access network. Packets are forwarded along with a flow, that is a kind of connection-oriented connection and established before delivering packets. For this purpose, we also propose a flow resolution method and a modified IPv6 header for delivering packet in the wireless Internet access network. In addition, the method to support the mobility of mobile stations is explained, and the implementation issues are discussed. In order to estimate the performance of the proposed method, we analyzed the delay time to deliver packets in the wireless Internet access network. The numerical results show that the proposed method is very efficient, in the view point of delay.
