Overview

WS-Management specifies a web services SOAP-based protocol for the management of personal computers, servers, devices, applications and more. The specification is based on Distributed Management Task Force (DMTF) open standards and Internet standards for Web Services. WS-Management provides a common way for systems to access and exchange management information across the IT infrastructure. A mapping of the DMTF-originated Common Information Model (CIM) into WS-Management is also defined. The CIM classes relate to each other by means of “association classes”. Each class is defined with a MOF (Managed Object Format) that specifies all of the properties and methods of the class as well as its dependence (if any) on another parent class.

Intel AMT resources can be viewed as a number of CIM objects. Their properties (“fields” in CIM terminology) and methods are the means for utilizing the capabilities of Intel AMT.

Intel AMT has two kinds of objects: objects based on the DMTF-defined classes (named with a prefix of CIM_), and Intel proprietary classes for functionality not covered by the standard classes (named with a prefix of AMT_ or IPS_). An application that interacts with Intel AMT to create a new object, get an existing object, put an object (a means to change the value of an existing object), delete an object, enumerate a list of objects, or invoke a method that is special to the object uses the standard operations of the WS-Management protocol to do this. The message sent to Intel AMT is a SOAP message that contains a serialized CIM request embedded in a WS-Management request with all of the necessary headers, namespace references, addressing, and so on.
