Techniques are provided for implementing the WS-DeviceProfile standard as a multi-threaded process ("DFM") executing on a multi-function peripheral ("MFP"). The DFM takes care of the discovery of devices and services on a network. The DFM also acts as a facility manager. The DFM implements various web services in a single component that applications can re-use. The DFM insulates these applications from some of the more complex details of the web services that the DFM implements. The MFP may comprise several different applications, each with a different specialized function. Each of these applications uses the web services provided by the DFM. The multi-threaded nature of the DFM permits new services to be added to the MFP dynamically. The threads can handle separate tasks concurrently. For example, one thread can handle communications with processes outside the MFP, while another thread can simultaneously handle communications with processes and applications inside the MFP.
