Abstract: 가상사설망을 지원하는 패킷-시간분할다중화 통합 시스템 및 그 방법이 개시된다. 이더넷 스위치부는 패킷의 VLAN ID를 기초로 포워딩 테이블을 참조하여 결정한 출력포트로 상기 패킷을 출력한다. 맵핑부는 TDM 데이터 회선과 일대일 대응되는 가상의 데이터 회선 포트를 생성하고 가상의 데이터 회선 포트를 출력포트로 맵핑한다. TDM 스위치부는 가상의 데이터 회선 포트를 통해 수신한 패킷을 TDM 전송망으로 출력한다. 이로써, 이더넷 가입자망의 다수의 가입자가 하나의 TDM 데이터 회선을 공유하여 사용할 수 있고 QoS 및 신뢰성이 높은 가상사설망을 구성할 수 있다.
