/** @defgroup RDMS Device and Network Management Service BIBBs

* to interoperably perform the device management functions enumerated in
* 22.2.1.5 for the BACnet devices defined therein.

* The network management BIBBs prescribe the BACnet capabilities required to
* interoperably perform network management functions.
*//** @defgroup DMDCC Device Management-Device Communication Control (DM-DCC)
* @ingroup RDMS
* 16.1 DeviceCommunicationControl Service <br>
* The DeviceCommunicationControl service is used by a client BACnet-user to
* instruct a remote device to stop initiating and optionally stop responding
* to all APDUs (except DeviceCommunicationControl or, if supported,
* ReinitializeDevice) on the communication network or internetwork for a
* specified duration of time. This service is primarily used by a human operator
* for diagnostic purposes. A password may be required from the client
* BACnet-user prior to executing the service. The time duration may be set to
* "indefinite," meaning communication must be re-enabled by a
* DeviceCommunicationControl or, if supported, ReinitializeDevice service,
* not by time.
*//** @defgroup NMRC Network Management-Router Configuration (NM-RC)
* @ingroup RDMS
* The A device may query and change the configuration of routers and
* half-routers.
* The B device responds to router management commands and must meet the
* requirements for BACnet Routers as stated in Clause 6.
*
* 6.4 Network Layer Protocol Messages <br>
* This subclause describes the format and purpose of the ten BACnet network
* layer protocol messages. These messages provide the basis for router
* auto-configuration, router table maintenance, and network layer congestion
* control.
