초록
최근 IEEE 802.11n 표준의 상용화와 함께 무선랜 환경에서 실시간 멀티미디어 서비스를 이용하려는 수요가 증가하고 있다. 그러나 IEEE 802.11i 보안표준에서 정의한 IEEE 802.1x 인증과정은 끊김 없는 실시간 멀티미디어 서비스를 제공하기에는 핸드오프 지연시간이 너무 길다. 본 논문은 고속의 핸드오프를 지원하기 위해 CAPWAP (Control And Provisioning Wireless Access Point) 아키텍처를 이용한 티켓 기반의 핸드오프 메커니즘을 소개한다.
Abstract
Recently, there is an increase in demand of real-time multimedia service in the WLAN environment, with a commercialization of IEEE 802.11n standard. However, the 802.1x authentication protocol is too slow to provide seamless real-time multimedia service, which defined in an IEEE 802.11i security standard. In this paper, a Ticket-based authentication mechanism in the CAPWAP(Control And Provisioning Wireless Access Point) architecture is introduced to support for the fast handoff.
