US: SAE Other J2735 - WAVE TCP

Description:

This solution is used within Canada and the U.S.. It combines standards associated with US: SAE Other J2735 with those for V-X: WAVE TCP. The US: SAE Other J2735 standards include upper-layer standards required to implement V2X information flows that do not yet have fully specified functionality and performance charcateristics. The V-X: WAVE TCP standards include lower-layer standards that support connection-oriented vehicle-to-any communications within ~300m using the Transmission Control Protocol (TCP) over Internet Protocol version 6 (IPv6) over IEEE WAVE in the 5.9GHz spectrum.

Relevant Regions:

• Canada
• United States

Solution Issues Severity: 31

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	Uncertainty about trust revocation mechanism	Security Gap	The mechanisms used to prevent bad actors from sending authorized messages is unproven.
True	High	Application specification not defined	ITS Info Gap	The logic, performance, and application security rules are not defined for this information flow.
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.
True	High	Regulatory Issue	Standardization Gap	Deployment of this standard is subject to regulatory approval, which is not currently expected to be granted for deployments in the near-term.
