US: SAE Platooning - LTE-V2X TCP

Description:

This solution is used within the U.S.. It combines standards associated with US: SAE Platooning with those for V-X: LTE-V2X TCP. The US: SAE Platooning standards include upper-layer standards required to manage platooning and cooperative adaptive cruise control. The V-X: LTE-V2X TCP standards include lower-layer standards that support connection-oriented vehicle-to-any communications using the Transmission Control Protocol (TCP) over Internet Protocol version 6 (IPv6) over C-V2X in the 5.9GHz spectrum.

Solution Issues Severity: 21

Solution Issues:

Default	Severity	Name	Type	Description
True	Low	Data not defined in standard format	ITS Info Gap	The definition of data concepts should conform to ISO 14817-1 to promote reuse among ITS.
True	Medium	Overlap of standards	Overlap	Multiple standards have been developed to address this information and it is unclear which standard should be used to address this specific information flow.
True	Medium	Regulatory Permission Needed	Standardization Gap	Deployment of this standard requires regulatory approval, which is currently subject to significant delays.
True	Medium	Still under development	Standardization Gap	A draft of the standard has been developed by the working group, but it was still under development at the time this analysis was performed.
True	Medium	Uncertainty about trust revocation mechanism	Security Gap	The mechanisms used to prevent bad actors from sending authorized messages is unproven.
True	High	Draft not available (Critical)	Standardization Gap	The standards development organization has established a work item for the subject standard but a draft is not available for this critical feature to enable the interface. The draft may be missing due to the work item being new or simply a lack of activity on the work item.
