Client-Server Architecture

Another component of the WBEM standards, xmlCIM (a specialization of the eXtensible Markup Language or XML), defines the encoding that CIM clients and servers use to comunicate about CIM objects, and the operations that can be performed on them. An example of a typical XML exchange is shown in the Appendix B, XML Example.

The HyperText Transfer Protocol (HTTP) is used to transport xmlCIM messages over a network. WBEM-compliant systems and devices implement an HTTP server. In the recommended implementation, the HTTP server listens on port 5988 for unencrypted communication or 5989 for encrypted communication.
