ATM(Asynchronous Transfer Mode)
Asynchronous Transfer Mode = 비동기전달모드
<GNS With ATM>
우선 ATM을 지원하는 라우터를 추가한다.
ex) C7200
※ 참고! GNS 셋팅

<ATM> VCI설정
ATM의 Configure 선택
Frame-relay의 DLCI처럼 ATM의 VCI를 설정해준다.

l 회선 교환의 실시간성 및 패킷 교환의 유연성을 통합시킨 연결 지향적 패킷 교환 복합 기술
- 주소 포맷, 신호 방식 등 : 회선 교환 방식 이용 (Circuit)
- ATM 셀 처리 등 : 패킷 교환 방식 이용 (Packet)
