Research On SNMP/XML Gateway

With the enormously evolved of the network, especially the rapid development of the Internet, the scale and complexity of networks has increased greatly. Under this background, the traditional simple network management protocols (SNMP) can not meet the requirement of network management. Management information and all the messages are described with XML in XML-based network management which has widely believed as the future of the network management for its merits. The research of this area can help us understand the development of the network management. And it can provide academic and practical supports to establish the standard of XML-based network management for our country.Although the SNMP was not declared as the international network management standard, it has been thought as the industrial standard for it was so simple and useful. A large number of network devices were designed to support SNMP, which represents huge investments. So it is difficult to replace SNMP with XML-based network management in a short time. This thesis designs a SNMP/XML gateway which is used to transfer management information between an XML-based manager and SNMP-based agents. XML-based manager can manage SNMP-based agents using this gateway. The proposed approach can save the money for change network devices and strive for more time to produce devices support XML-based network management.The architecture of SNMP-base network management and the XML-based network management are analysed and compared with each other in this thesis. We design the architecture of the SNMP/XML Gateway and introduce the function of each module. Key technology including the translation of the protocol operations and the implementation of the SNMP module are described in details. We also develop a SNMP MIB to XML Schema translation algorithm and design a MIB translator using this algorithm. At the last, we summarize the whole thesis and discuss the prospect of the area.
