scan network for devices

End users scan network for devices through their end device and have certain expectations of appropriate service levels. For example, typical users expect a voice call on a standard phone to be of toll quality. Yet they do not expect that same quality level from a cell phone or a voice call spoken into a microphone on a personal computer. This is the general expectation, regardless of the fact that all three calls might be carried by the same network in the same manner

The end user has no concept of and typically very little interest in the capabilities of the networks in betweenunless, of course, the quality of the network response is lacking. Therefore, end users' perception of the quality of the service that they receive is based on previously observed behavior on similar devices (examples include a PSTN phone call, a PBX phone call, a bank teller application, and the refresh of a web page display) and the cost of the service (which, in an enterprise network, the general end user perceives scan network for devices).
