|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.|
Many serious issues. This category includes solutions that have not been standardized, or do not have a basic level of interoperability or security. Consider selecting a different communications solution or if this is not possible (eg. a pilot of a new application that has not been standardized), take additional measures to provide an acceptable level of security or interoperability.
