SNMP(Simple Network Management protocol) 기반 망 관리 에이전트 기능을 구현하기 위해서는 에이전트 시스템 특성에 따른 표준 MIB(Management Information Base)을 구현하여 SNMP가 사용할 수 있도록 하여야 한다. 이때, SNMP 망 관리 에이전트 기능에 구현된 MIB은 망 관리를 위해 해당 객체(object)에 접근할 수 있는 가상의 정보일 뿐 MIB에 정의된 각 객체에 대한 값은 해당 MIB 정보를 제공하는 시스템 기능(이하 시스템 기능이라 함.)에서 제공된다. 이때 SNMP 망 관리 에이전트 기능에서는 시스템 기능과 어떠한 정합 방법으로 통신하는가 하는 문제는 시스템 구현 사항이다. 일반적으로 시스템 기능에서 각 객체별로 접근 가능한 API를 제공하여 SNMP 망 관리 에이전트 기능에서 이를 이용하도록 구현되어 있다. 본 논문에서는 이러한 방식의 문제점을 살펴보고, 테라 라우터에 구현하는 SMUX(SNMP Multiplexing) 프로토콜 정합 방법 및 IPC 정합 방법을 설명한다. 또한 IPC통신시 재사용 가능한 메시지 구조를 제안한다.
