A Novel Technique for SNMP Bandwidth Reduction: Simulation and Evaluation

One of the most popular and widely used Network Management Protocols (NMP) is SNMP. SNMP is extremely simple and versatile but it has scalability problems. A number of alternative NMPs such as RMI interfaces, CORBA [1] and RMON [2] have been attempted to overcome the problems with SNMP. However, these interfaces lack the standardization effort and simplicity of the usage that SNMP provides. So currently, every application develops models to achieve the desired level of scalability on its own. In this paper, we demonstrate a new technique to decrease a number of messages between manager and agent in the SNMP (i.e. traffic reduction). The base idea of our technique is to make a system manager keeps the MIB objects that are frequently required. We simulate our proposed technique using a network simulator called NS2. We compare our proposed technique with the Kwang Sik Shin attempt [3] and general polling technique [4].
