* The Who-Is service is used by a sending BACnet-user to determine the device * object identifier, the network address, or both, of other BACnet devices * that share the same internetwork. * The Who-Is service is an unconfirmed service. The Who-Is service may be used * to determine the device object identifier and network addresses of all devices * on the network, or to determine the network address of a specific device whose * device object identifier is known, but whose address is not.
* The I-Am service is also an unconfirmed service. The I-Am service is used to * respond to Who-Is service requests. However, the I-Am service request may be * issued at any time. It does not need to be preceded by the receipt of a * Who-Is service request. In particular, a device may wish to broadcast an I-Am * service request when it powers up. The network address is derived either * from the MAC address associated with the I-Am service request, if the device * issuing the request is on the local network, or from the NPCI if the device * is on a remote network. */ #endif
