데이터, 음성, 영상등에 대한 다양한 종류의 서비스들이 요구되어지면서 ATM기술은 중요한 역할을 하게 될 것이다. 그러나 기존의 AAL Type들로는 저속의 짧은 가변길이를 Packet을 사용하는 서비스를 지원하기는 문제점이 있었다. 이러한 문제의 해결을 위해 AAL Type 2는 저속이면서 짧고 가변의 길이를 가지는 패킷들을 사용하며 지연에는 민감한 특성을 가지는 응용들을 지원하기 위해 만들어 졌다. 본 논문에서는 AAL Type 2의 서비스를 지원하는데 있어 ATM 망에서 AAL Type 2 ATM Cell들을 Switching하기 위한 AAL 2 Switch의 구조를 제안하고 CAD 설계하였다. 제안한 AAL2 Switch는 Module화를 통하여 확장성을 가지도록 설계하였다. 또한 Computer Simulation을 통하여 성능 분석하였다.
