실시간 네트워크 관리를 위한 SNMP 의 확장에 관한 연구
김동수(Kim Dong Soo),정태명(Chung Tai Myong) 한국정보처리학회 1999 정보처리학회논문지 Vol.6 No.2
In real-time systems, the accurate response time and minimal communication delay is highly desired. However, a conventional SNMP uses network resources inefficiently and introduces too much network traffic for periodic requests in particular. This paper presents an extended SNMP called Real-Time SNMP. It is designed to support real time applications with time constraints to provide more accurate response time and less network traffic for periodic SNMP requests. While keeping current Client/Server implementation unchanged, we simply add a periodic SNMP request PDU which is sent from management station to agents. In addition, the module of the Real-Time SNMP agent works between management station and each SNMP agent module and extended SNMP PDU. We also show the experimental results that indicate more punctual response time and reduced communication delay using the proposed Real-Time SNMP.
