Data Distribution System --> Other Data Distribution Systems:
data provision

This triple is bi-directional. See also Other Data Distribution Systems --> Data Distribution System: data provision

Definitions

data provision (Information Flow): Data provision provides the source material for a publish-subscribe or query-retrieval data distribution scheme. This is the 1 of the 1:N data distribution architecture. This flow is a super-flow; it does not define data elements but is inclusive of any flow implemented using publish-subscribe or query-retrieval methods.

Data Distribution System (Source Physical Object): The 'Data Distribution System' collects, processes, and distributes ITS data, connecting data producers with data consumers and facilitating data exchange.

Other Data Distribution Systems (Destination Physical Object): Representing another Data Distribution System, 'Other Data Distribution Systems' is intended to provide a source and destination for information exchange between peer (e.g. inter-regional) data distribution systems. It supports modeling of projects or regions that include multiple interconnected data distribution systems that together manage data distribution in the connected vehicle environment.

Communication Solutions

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

Selected Solution

Data for Distribution (TBD) - OASIS AMQP

Solution Description

This solution is used within Canada, the E.U. and the U.S.. It combines standards associated with Data for Distribution (TBD) with those for OASIS AMQP. The Data for Distribution (TBD) standards include a placeholder for upper-layer standards necessary to define the data (elements and structures) necessary to complete a solution for the information flow based on data distribution technologies. The data standard will need to include a specific customization for the desired data distribution technology used (e.g., Kafka, DDS, etc.).. The OASIS AMQP 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).

  Confidentiality Integrity Availability
Rating High High Moderate
Basis This value is derived from the specific flows satisfied by this super-flow. HIGH is set because some flows may require it. If the implementation includes flows with only a MODERATE or LOW confidentiality requirement, then this could be MODERATE or LOW, as appropriate. This value is derived from the specific flows satisfied by this super-flow. HIGH is set because some flows may require it. If the implementation includes flows with only a MODERATE integrity requirement, then this could be MODERATE. This value is derived from the specific flows are satisfied by this super-flow. MODERATE is set because some flows may require it. If the implementation includes flows with only a LOW availability requirement, then this could be LOW. HIGH is not considered; any flow requiring HIGH availability will not use DDS.
