SNMP 기능확장을 통한 Network 성능 향상에 관한 연구 = Research on Improvement of Network Performance by Extending a Function of SNMP

다국어 초록 (Multilingual Abstract)

On internet environment multimedia information containing voice and image is tramitted, which is tens times or hundreds times larger than oridnary information Analytic types for network management in this environment are consisted of a real time analysis, a basis analysis and an intensive analysis.
An intensive analysis is to gather trend information on specific objects periodically, and to analyze this information in order to monitor network conditions When SNMP is applied to collect the trend information, it brings on an increase of network load, a delay of response time and a decrease of accuracy of data collection since an agent responds to each managers' polling.
In this paper, an efficient SNMP is proposed and implemented to add time variables in the existing SNMP PDU It minimizes unnecessary traffic at an intensive analysis between manager and agent, and collects trend information accurately The results of experiments show that it has compatibility with the existing SNMP, decreases an amount of network traffic greatly and increases the accuracy of data collection.
