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 and RMON have been attempted to overcome the problems with SNMP. However, these interfaces lack the standardization effort and simplicity of the usage that SNMP provides. This paper demonstrates a new technique to decrease a number of messages between manager and agent in the SNMP (i.e. traffic reduction). The base idea of the technique is to make a system manager keeps the MIB objects that are frequently required. They simulate the proposed technique using a network simulator called NS2.
