Communications Profiles

The communications profiles reflect likely implementation choices have been developed and assigned, where applicable, to triples. The communications profiles have been developed following closely the naming practices of the OSI (Open Systems Interconnection) Model.

ID	Name	Description	Profile Diagram
CCMS	CCMS Communications	This profile identifies applicable standards for secure communications with the Cooperative ITS Credentials Management System (CCMS).
Contact-Proximity-Interface	Proximity Communication Interface	This profile describe applicable standards used in close proximity communications.
DSRC-UDP	Vehicle-to-Vehicle/Infrastructure using UDP	This profile describes a set of standards applicable to broadcast, frequent (non-constant), medium latency vehicle- to-vehicle and vehicle-to-infrastructure communications using the User Datagram Protocol (UDP) over Internet Protocol version 6 (IPv6) over the 5.9GHz spectrum.
DSRC-WSMP	Vehicle-to-Vehicle/Infrastructure using WSMP	This profile describes a set of standards applicable to broadcast, near constant, low latency vehicle- to-vehicle and vehicle-to-infrastructure communications using the WAVE Short Messaging Protocol (WSMP) over the 5.9GHz spectrum.
GENERIC-TEMPLATE	No Standards Identified	This profile is used to show that the CVRIA does not contain standards applicable for this interface.
NTCIP-DATEX	NTCIP using DATEX	This profile describes an alternative set of standards applicable to communications between entities using ISO TC204 WG9 DATa Exchange(DATEX). Information messages are encoded using the NTCIP Octet Encoding Rules (OER).
NTCIP-SMTP	NTCIP using SMTP	This profile describes an alternative set of standards used to communicate with ITS Roadway Devices that uses the NTCIP Octet Encoding Rules (OER), a standard developed specifically for the transportation industry. This template is used primarily for communication with traffic signal controllers, where second-per-second communications is required. This template also includes standards for SNMP traps, that allows an ITS Roadway Device to initiate event-driven communications with a receiver.
NTCIP-SNMP	NTCIP using SNMP	This profile describes applicable standards for communicating between with ITS Roadway devices using the simple network management protocol (SNMP).
Position-Location-Interface	Position-Location Interface	This partial profile, showing only physical objects and flow, describes communications between connected vehicle equipment and on board geolocation equipment such as a GPS receiver.
RSE-C2F	RSE - Center to Field Communications	This profile describes applicable standards for Center to Field communications with RSEs. Common internet standards (HTTPS and TCP) are used in this profile.
RSE-C2F-SNMP	RSE - Center to Field Communications - SNMP	This profile identifies applicable standards for Center to Field communications with RSEs. This profile uses the Simple Network Management Protocol (SNMP), an Internet-standard protocol for managing devices on IP networks.
RSE-F2F	Roadside Equipment to ITS Roadway Equipment	This profile describes standards applicable to communications between roadside equipment and other field equipment such as traffic signal controllers that is represented by ITS Roadway Equipment in CVRIA.
RSEGateway-VehicleDestination	Vehicle Communications via RSEs, Vehicle Destination	This profile describes an alternative set of standards used in vehicle communications where one or more RSEs act as a gateway with the vehicle as destination.
RSEGateway-VehicleSource	Vehicle Communications via RSEs, Vehicle Source	This profile describes an alternative set of standards used in vehicle communications where one or more RSEs act as a gateway with the vehicle as source.
Time	Network Time Protocol	This profile includes a collection of standards that support the Network Time Protocol that allows NTP servers to provide time synchronization services to other NTP servers and clients.
Vehicle-On-Board	Vehicle-On-Board	This partial profile, showing only physical objects and flow, describes communications between equipment that reside on the vehicle. The CVRIA does not contain any specific information on standards for on-board vehicle communications.
WAB	Wide-Area-Broadcast	This profile shows a wide area wireless communications system that offers broadcast services with regional, national, or continental coverage, enabling communications with vehicles and traveler mobile devices at any location on or off the road network. Examples of this link include satellite and terrestrial radio digital broadcast services.
WAB-Via-WAID	Wide-Area-Broadcast-Via-WAID	This profile shows a wide area wireless communications system that offers broadcast services with regional, national, or continental coverage, enabling communications with vehicles and traveler mobile devices at any location on or off the road network. In this profile, the Wide-Area Information Disseminator (WAID) CVRIA Physical Object provides broadcast communications services enabling transportation centers to communicate with all equipped transportation users in their region. Examples of this link include satellite and terrestrial radio digital broadcast services.
WAW-ASN1	Wide Area Wireless using ASN.1 as encoding method	This profile describes applicable ASN.1 standards used in transmissions over wide area wireless communications.
WAW-WWWBrowser-JSON	Wide Area Wireless using JSON as encoding method	This profile describes applicable IETF JSON and W3C web browser standards (e.g., HTML5 and Web Sockets) for transmissions over wide area wireless communications.
WAW-XML	Wide Area Wireless using XML as encoding method	This profile describes applicable XML and W3C web services standards used in transmissions over wide area wireless communications.
XML	eXtensible Markup Language	This profile describes a set of standards applicable to communications between entities using the Web Services standards of the World Wide Web Consortium (W3C) and the IETF (Internet Engineering Task Force). Information messages are encoded using the eXtensible Markup Language (XML).
