This solution is used within 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.

| TransNet | IETF RFC 2460 | Internet Protocol, Version 6 (IPv6) Specification | This standard (RFC) specifies version 6 of the Internet Protocol (IPv6), also sometimes referred to as IP Next Generation or IPng. |
|---|
| TransNet | IETF RFC 4291 | IP Version 6 Addressing Architecture | This standard (RFC) defines the addressing architecture of the IP Version 6 (IPv6) protocol. It includes the IPv6 addressing model, text representations of IPv6 addresses, definition of IPv6 unicast addresses, anycast addresses, and multicast addresses, and an IPv6 node's required addresses. |
|---|
| TransNet | IETF RFC 4861 | Neighbor Discovery for IP version 6 (IPv6) | This standard (RFC) specifies the Neighbor Discovery protocol for IP Version 6. IPv6 nodes on the same link use Neighbor Discovery to discover each other's presence, to determine each other's link–layer addresses, to find routers, and to maintain reachability information about the paths to active neighbors. |

Multiple significant and minor issues. For existing deployments, the chosen solution is likely deficient in security or management capabilities, and the issues should be reviewed and upgrades developed as needed. Some solutions in this category may also be becoming obsolete from an interoperability perspective and if this is the case, then upgrades should be planned as soon as possible. For new deployments, the solution may be viable for pilots when applied to the triples it supports; such pilot deployments should consider a path to addressing these issues as a part of their design activities. The solution does not provide sufficient interoperability, management, and security to enable proper, full–scale deployment without additional work.
