SNMP는 네트워크의 장비들 사이에서 관리 정보를 주고받는 응용 계층 프로토콜로 동작 방법은 매우 간단하다. SNMP는 PDU를 통해서 관리 정보의 이름과 값을 서로 교환한다. 지금까지 네트워크 관리는 SNMP를 이용해 콘솔 기반으로 관리되었기 때문에 매우 불편했다. 이 논문에서는 새롭게 디자인된 사설 MIB와 GUI를 통한 웹 기반 SNMP 망 관리 시스템을 구현한다. 또한 확장성 문제를 해결하기 위해 가상 에이전트를 제안하고 구현한다. 제안된 가상 에이전트를 사용함으로써, 무분별한 트랩 발생에 대한 필터링과 계층적인 망 관리가 가능하게 된다.
