Developing efficient XML-SNMP model: An XML-template based approach

XML-SNMP based network management model is essential parts of the network management infrastructure. It is generally recognised that there are two problems remained unsolved for this kind of model. These two problems are load balance of the XML manager and the potential bottleneck of the XML/SNMP gateway. This paper presents a novel XML-template based approach to tackle these two problems. We developed three XML templates including host, graph, and data query templates. This paper gives detail discussion of the three templates in regard of the structure, content and relationship as well as the mapping mechanism in the relational databases. The experimental results performed on a real deployed XML-SNMP system demonstrate the effectiveness of the proposed approach. When compared with traditional XML-SNMP system, our approach effectively reduces the types and quantities of management data and overhead of translation between XML and SNMP. The proposed approach solves the load balance and bottleneck issues resulting in significantly overall performance improvement of the XML-SNMP model.
