Definitions

personnel device fault data (Information Flow): Personnel device fault information that can be used to identify personnel devices that require initialization, reconfiguration, repair or replacement. This flow identifies the device, the nature of the fault, and associated error codes and diagnostic data.

Service Monitor System (Source 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.

Center (Destination Physical Object): This general physical object is used to model core capabilities that are common to any center.

Communication Solutions

(None-Data) - Secure Internet (ITS) (32)
(None-Data) - Apache Kafka (36)
(None-Data) - OMG DDS (36)
(None-Data) - OASIS MQTT (42)
(None-Data) - OASIS AMQP (45)

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

(None-Data) - OASIS MQTT

Solution Description

This solution is used within Australia and the U.S.. It combines standards associated with (None-Data) with those for OASIS MQTT. The (None-Data) standards include an unspecified set of standards at the upper layers. The OASIS MQTT standards include lower-layer standards that support data distribution of specific types of data.

Note that some layers might have alternatives, in which case all of the gap icons associated with every alternative may be shown on the diagram, but the solution severity calculations (and resulting ordering of solutions) includes only the issues associated with the default (i.e., best, least severe) alternative.

Interoperability	Description
Regional	Interoperability throughout the geopolitical region is highly desirable, but if implemented differently in different transportation management jurisdictions, significant benefits will still accrue in each jurisdiction. Regardless, this Information Flow Triple should be implemented consistently within a transportation jurisdiction (i.e., the scope of a regional architecture).

Security

Information Flow Security
	Confidentiality	Integrity	Availability
Rating	Moderate	Moderate	Moderate
Basis	Device status information should not be viewable by third parties, as those with criminal intent may use this information toward their own ends.	If incorrect or changed, could lead to inappropriate maintenance activity, which has a significant cost in itself and contributes negatively to system operational status. Scope is small, but impact significant if this occurs with many instances.	A delay in reporting this may cause a delay in necessary maintenance. Considered higher availability requirement than the source flow (RSE status) because this information aggregates many instances of the source.
