Snmp for Ethernet Networks SETH: A Network Benchmark Toolkit for Managing Routers Statistical Information

In this paper authors present a new open source SNMP manager application called SETH. This application includes the following major attributes over existing management tools: MIB file parsing capabilities, automatic discovery of network topology and variable up to real-time probing frequency of network equipment in order to extract useful statistical information regarding network conditions. Network information is acquired from network devices using real-time SNMP probes close to agent systems clock granularity. Then re-configurable network metrics are calculated and visualized. Additionally, SNMP trap or notification messages send by routers, indicating cases of network emergencies, are also recorded. Graphical visualization of metric values, network correlation functions and support for all SNMP protocol versions is also provided by the tool.
