Connected Vehicle Roadside Equipment --> Service Monitor System:
RSE status
Definitions
RSE status (Information Flow): Monitoring of RSE device status including current mode, operational status, and configuration settings. It includes device housekeeping/heartbeat monitoring and includes network information, the status of installed applications, the configuration of managed devices, cybersecurity and physical security status of the RSE.
Connected Vehicle Roadside Equipment (Source Physical Object): 'Connected Vehicle Roadside Equipment' (CV RSE) represents the Connected Vehicle roadside devices that are used to send messages to, and receive messages from, nearby vehicles using Dedicated Short Range Communications (DSRC) or other alternative wireless communications technologies. Communications with adjacent field equipment and back office centers that monitor and control the RSE are also supported. This device operates from a fixed position and may be permanently deployed or a portable device that is located temporarily in the vicinity of a traffic incident, road construction, or a special event. It includes a processor, data storage, and communications capabilities that support secure communications with passing vehicles, other field equipment, and centers.
Service Monitor System (Destination Physical Object): The 'Service Monitor System' represents one or more center-based systems that provide monitoring, management and control services necessary to other applications and/or devices operating within the Connected Vehicle Environment. These support services enable other applications to provide transportation services.

Interoperability | Description |
---|---|
Local | In cases where an interface is normally encapsulated by a single stakeholder, interoperability is still desirable, but the motive is vendor independence and the efficiencies and choices that an open standards-based interface provides. |

Basis | Will include some sort of identifier for the RSE and given the content of the flow this will indicate what operations the RSE is capable of. This should be considered actionable intelligence: if a hostile actor knows what field devices have particular capabilities, he can target an attack to maximum effect. | Since this is used to monitor the health of the RSE, any corruption or modification of this information could lead to unnecessary maintenance activity, or delay necessary such activity. Impact will be limited to the RSEs who's flows were so affected. | Local connections must be fully available, as it suggests the presence of maintenance personnel attempting to work on the RSE. Without this interface, there is little the field personnel can do, effectively making the RSE useless. |
