Remote MIB-item look-up service

Despite some deficiencies, the Internet management framework is widely deployed and thousands of management information base (MIB) modules have been defined thus far. These modules are used by implementers of agent software, as well as by managers and management applications, to understand the syntax and semantics of the management information that may be exchanged. At the manager\´s side, MIB modules are usually stored in separate files, which are maintained by the human manager and read by the management application. Since maintenance of this file repository can be cumbersome, management applications are often confronted with incomplete and outdated information. To solve this "meta-management" problem, this paper discusses the design of a remote look-up service for MIB-item definitions. Such a service facilitates the retrieval of missing MIB module definitions, as well as definitions of individual MIB-items. Initially the service may be provided by a single server, but other servers can be added at later stages to improve performance and prevent copyright problems. It is envisaged that vendors of network equipment will also install servers, to distribute their vendor specific MIB. The paper describes how the service, which is provided on a best effort basis, can be accessed by managers/management applications, and how servers inform each other about the MIB modules they support.
