Wbem Standards-based Network Management Research

In recent years, enterprise distributed networks exponentially grow in size and complexity, but the network environments assemble hardware and software from a variety of vendors. As a result, networks are expensive to maintain and difficult to manage, network administrators are often required to understand relevant technologies of the products from various companies. For this reason is that the real cost of maintaining a distributed computer network—extends far beyond the initial purchase of hardware and software. With these escalating costs in mind, Microsoft and others of the Distributed Management Task Force (DMTF) are working together on several initiatives designed. Key among these efforts is Web-Based Enterprise Management (WBEM), an industry initiative that establishes management infrastructure standards and provides a standardized method for accessing managed resources from various hardware and software management systems. WBEM vastly simplifies the process of creating management applications, and thus of managing enterprise networks.Web-Based Enterprise Management (WBEM) is a set of management and Internet standard technologies developed to unify the management of enterprise computing environments. WBEM provides the ability for the industry to deliver a well-integrated set of standard-based management tools leveraging the emerging Web technologies. The DMTF has developed a core set of standards that make up WBEM, which includes a data model, the Common Information Model (CM) standard; an encoding specification, xmlCM Encoding Specification; and a transport mechanism, CM Operations over HTTP. The Windows Management Instrumentation (WMI) technology is the Microsoft implementation of the Distributed Management Task Force (DMTF) Web-Based Enterprise Management (WBEM) initiative that extends the Common Information Model (CM) to represent management objects in Windows-based management environments. The Common Information Model, also a DMTF standard, is an extensible data model for logically organizing management objects in a consistent, unified manner in a managed environment.This paper provides an overview of WBEM, including a discussion of its history. Combines with the experiments and issues of the software project development, it briefly describes the WBEM standard components and the WBEM-compatible Windows management architecture, brings forward the simple, rapid and effective methods of how to use them as a framework for developing network management software, and a good effect is produced in the practical application.The content of the thesis can be described as following:In the first part, it presents an basic concept of the Web-Based Enterprise Management (WBEM), the Common Information Model (CIM) and the architecture of the Microsoft WBEM Implementation (WMI) technology.? Web-Based Enterprise Management (WBEM) is an industry initiative created by the DMTF. It provides a standardized way to access information from various hardware and software management systems in an enterprise environment.? CM, as part of the WBEM initiative, is an object-oriented data model for describing management information. CIM includes the following information models: A core model, Common models and Extension schemas.? The architecture of the WMI technology, an implementation of WBEM initiative for Microsoft Windows operating systems., is a management infrastructure that supports the syntax of CIM, the Managed Object Format (MOF), and a common programming interface.In the second part, using WMI technology, it studies and brings forward the methods to develop the WMI applications and WMI providers.? In WMI Applications, developers can use the COM application programming interface (API) and scriptable API to access CIM Object Manager directly.? Use the WMI APIs , developers can to write WMI providers to extend the information model to cover new devices, applications, and so on.. WMI Extensions to the Windows Driver Model (WDM) can capture instrumentation data and events from device drivers and kernel-side components.Finally, I use these methods to design and develop the Server Manager software which is network management solution based on WMI technologies. It enables for the administrators to realize the Unified, safe, centralized management of the whole network environment from any Web browser. The system administrators can retrieve all kinds of device information, such as Processor Type, Memory, System Board etc, and view real-time asset and health information about the managed system. When critical thresholds are crossed, Server Manager software will automatically notifies network administrators. Server Manager software improves system availability, and reducing overall infrastructure costs.
