The implementation of dynamically updating MIB variables for SNMP-based network management

摘要

The implementation of dynamically updating Management Information Base (MIB) variables for Network Management based on simple network management protocol (SNMP) is a necessary auxiliary tool for simulation testing various SNMP-based network management systems. In order to monitor the performance of an Ethernet passive optical network (EPON) via an element management system (EMS), the related MIB variables values need to be dynamically updated according to the required period as well as data changing rules following the requirement of EPON EMS performance monitoring. This paper presents the design, implementation, test and analysis of the dynamically updating MIB variables tool by use of a Java programming development environment. The dynamically updated MIB variables tool achieves the functions of dynamically updating the MIB variables value according to certain rules defined by the network management requirement through the set operation to update and use the operation to obtain the MIB variables value.
