|---|---|---|---|
| Access | Wireless Internet Alternatives (NA) | A set of alternative standards that supports any technology that allows a mobile device (e.g., a vehicle) to connect to the Internet (or an intranet) while stationary or moving within a limited area. For example, this would include both Wi-Fi and cellular technologies among others. NOTE: Use of the WAVE Subnet should be coupled with use of IEEE 1609.3 at the TransNet Layer. | |
| Mgmt | Bundle: SNMPv3 MIB | A bundle of standards (RFCs) that groups the common management information bases (MIBs) used to manage IP networks at the transport layer and below using SNMPv3. | |
| Security | Secure Session Alternatives | A set of alternative standards that identifies standards that are used to establish and maintain secure Internet sessions. If an information exchange does not require encryption, the (D)TLS session can negotiate NULL encryption. NOTE: If TCP is selected in the TransNet Layer, one of the TLS alternatives must be selected from this alternative set; if UDP is selected in the TransNet Layer, one of the DTLS alternatives must be selected from this alternative set. | |
| TransNet | Internet Transport Alternatives | A set of alternative standards that identifies the two major options for the transport layer for mainstream IP-based deployments. | |
| TransNet | IP Alternatives | A set of alternative standards that allows for the selection of IPv4 or IPv6. |

| Facilities | IETF RFC 9110 | IETF RFC 9110 HTTP Semantics | The Hypertext Transfer Protocol (HTTP) is a stateless application-level protocol for distributed, collaborative, hypertext information systems. This document describes the overall architecture of HTTP, establishes common terminology, and defines aspects of the protocol that are shared by all versions. In this definition are core protocol elements, extensibility mechanisms, and the "http" and "https" Uniform Resource Identifier (URI) schemes. |
| Facilities | IETF RFC 9112 | IETF RFC 9112 HTTP/1.1 | The Hypertext Transfer Protocol (HTTP) is a stateless application-level protocol for distributed, collaborative, hypertext information systems. This document specifies the HTTP/1.1 message syntax, message parsing, connection management, and related security concerns. |
| Facilities | Presentation Format Alternatives | A set of alternative standards for formatting that can be used for data presentation. | |
| Facilities | SAE J2354 | SAE J2354 ATIS Messages | This standard defines how to exchange data for Advanced Traveler Information Systems (ATIS). The messages contained herein address all stages of travel (pre-trip and en-route), all types of travelers (drivers, passengers), all categories of information, and all platforms for delivery of information (in-vehicle, portable devices, kiosks, etc.). |
| ITS Application Entity | SAE J2353 | SAE J2353 ATIS DD | This document provides a set of core data elements needed by information service providers for Advanced Traveler Information Systems (ATIS). The data dictionary herein provides the foundation for ATIS message sets for all stages of travel (pre-trip and en route), all types of travelers (drivers, passengers), all categories of information, and all platforms for delivery of information (in-vehicle, portable devices, kiosks, etc.). The elements of this document are the basis for the SAE ATIS Message Set Standard J2354 and are entered into the SAE Data Registry for ITS wide coordination. |
One serious or several significant issues. This category often includes proprietary or partial solutions. The communications solution may fail to provide even a base level of interoperability and security. Consider alternative solutions, or define specific revisions or upgrades that would provide a level of interoperability or security that are needed for the deployment.
