* 16.9 Who-Has and I-Have Services <br>
* The Who-Has service is used by a sending BACnet-user to identify the device
* object identifiers and network addresses of other BACnet devices whose local
* databases contain an object with a given Object_Name or a given Object_Identifier.
* The I-Have service is used to respond to Who-Has service requests or to
* advertise the existence of an object with a given Object_Name or
* Object_Identifier. The I-Have service request may be issued at any time and
* does not need to be preceded by the receipt of a Who-Has service request.
* The Who-Has and I-Have services are unconfirmed services.
