본 논문에서는 네트워크 관리 시스템에서 SNMP(Simple Network Management Protocol) 프로토콜을 이용한 중앙 집중형 방식과 이동 에이젠트(mobile agent)를 이용한 분산방식 각각의 성능을 평가하기 위한 성능평가 모델을 제시한다. 먼저 균등 네트워크 상에서 적용 가능한 모델을 제시하고 실제 실험을 통하여 각 파라미터 값의 변화에 따른 네트워크 수행 시간을 비교한다. 다음으로 비균등 네트워크에 적용 가능하도록 모델을 확장하고, 제시한 모델을 응용하여 실제 가상의 시나리오 하에서 네트워크 소요시간을 줄일 수 있는 방안과 그에 대한 실험 결과를 제시한다. 본 성능평가 모델은 차후 네트워크 관리시스템을 개발할 때에, 효율적인 패러타임(paradigm)과 수행 구조를 선택하는데 도움이 될 수 있을 것이다.
