Extension of SNMP function for improvement of network performance

Abstract

A manager requests a MIB value for a desired object to an agent by management policy defined in SNMP, and then it responds to the manager. So, it causes a lot of network traffic between them. Specially, repetitious occurrence of sending-receiving information is very inefficient for a same object when a trend analysis of traffic is performed. In this paper, an efficient SNMP is proposed to add new PDUs into the existing SNMP in order to accept time function. Utilizing this PDU, it minimizes unnecessary sending-receiving message and collects information for trend management of network efficiently. This proposed SNMP is tested for compatibility with the existing SNMP and decreases amount of network traffic largely. © Springer-Verlag 2004.
