SMIng - Eine neue Sprache zur Definition von Management-Informationen

Frank Strauß


More than ten years various standardization bodies are concerned with the methodic management of computer networks. All concepts include an information model, that is used for the structuring of management information and contains a language that allows a formal description of managed objects and events. In the area of internet management, this language is the Structure of Management Infor- mation (SMI), presently defined in two versions, SMIv1 and SMIv2. They are widely deployed, although their specifications suffer from some drawbacks concerning unambi- guousness, clearness, integrity, and extensibility. As a consequence, there are insufficient definitions of management information and erroneous implementations of parsers. This thesis presents the systematic design and the complete specification of a new language for the description of management information, based on the comparison of the most com- mon information models. “SMIng” eliminates the known problems whilst remaining se- mantically compatible. Secondly, a software library for management information has been developed. Based on this library tools for checking descriptions and converting from SMIv2 to SMIng and from SMIng to SMIv2 prove the approach of SMIng and allow a cost-efficient re-usability of existing descriptions of management information.
