US: GTFS - Secure Internet (ITS)

Description

This solution is used within the U.S.. It combines standards associated with US: GTFS with those for I–I: Secure Internet (ITS). The US: GTFS standards include upper–layer standards required to implement public, transit–related communications. The I–I: Secure Internet (ITS) standards include lower–layer standards that support secure communications between ITS equipment using X.509 or IEEE 1609.2 security certificates.

Includes Standards

LevelDocNumFullNameDescription
MgmtIETF RFC 3411An Architecture for Describing Simple Network Management Protocol (SNMP) Management FrameworksThis standard (RFC) defines the basic architecture for SNMPv3 and includes the definition of information objects for managing the SNMP entity's architecture.
MgmtIETF RFC 3412Message Processing and Dispatching for the Simple Network Management Protocol (SNMP)This standard (RFC) contains a MIB that assists in managing the message processing and dispatching subsystem of an SNMP entity.
MgmtIETF RFC 3413Simple Network Management Protocol (SNMP) ApplicationsThis standard (RFC) includes MIBs that allow for the configuration and management of remote Targets, Notifications, and Proxys.
MgmtIETF RFC 3414User–based Security Model (USM) for version 3 of the Simple Network Management Protocol (SNMPv3)This standard (RFC) contains a MIB that assists in configuring and managing the user–based security model.
MgmtIETF RFC 3415View–based Access Control Model (VACM) for the Simple Network Management Protocol (SNMP)This standard (RFC) contains a MIB that supports the configuration and management of the View–based access control model of SNMP.
MgmtIETF RFC 3416Version 2 of the Protocol Operations for the Simple Network Management Protocol (SNMP)This standard (RFC) defines the message structure and protocol operations used by SNMPv3.
MgmtIETF RFC 3418Management Information Base (MIB) for the Simple Network Management Protocol (SNMP)This standard (RFC) defines the MIB to configure and manage an SNMP entity.
MgmtIETF RFC 4293Management Information Base for the Internet Protocol (IP)This standard (RFC) defines the MIB that manages an IP entity.
SecurityIETF RFC 5280Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) ProfileThis standard (RFC) defines how to use X.509 certificates for secure communications over the Internet.
SecurityIETF RFC 8446The Transport Layer Security (TLS) ProtocolThis standard (RFC) specifies Version 1.3 of the Transport Layer Security (TLS) protocol. The TLS protocol provides communications security over the Internet. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery.
ITS Application EntityGTFS RealtimeGeneral Transit Feed Specification RealtimeThis document defines a feed specification that allows public transportation agencies to provide real–time updates about their fleet to application developers. It is an extension to GTFS (General Transit Feed Specification), an open data format for public transportation schedules and associated geographic information. GTFS Realtime was designed around ease of implementation, good GTFS interoperability and a focus on passenger information.
ITS Application EntityGTFSGeneral Transit Feed SpecificationThis document defines a common (open data) format for exchanging public transportation schedules and associated geographic information.
FacilitiesIETF RFC 7230Hypertext Transfer Protocol (HTTP/1.1): Message Syntax and RoutingThis standard (RFC) defines the main Application Layer protocol used for the world–wide web.
FacilitiesISO 21320–1Information technology — Document Container File — Part 1: CoreISO/IEC 21320–1 specifies the core requirements for 1) document container files, and 2) implementations that produce and/or consume document container files. It normatively references the Zip File Format Specification version 6.3.3 of PKWARE(R) Inc. Document container files are conforming Zip files as specified by that document.
FacilitiesIETF RFC 4180Common Format and MIME Type for Comma–Separated Values (CSV) FilesThis standard (RFC) documents the format used for Comma–Separated Values (CSV) files and registers the associated MIME type "text/csv".
TransNetIETF RFC 2460Internet Protocol, Version 6 (IPv6) SpecificationThis standard (RFC) specifies version 6 of the Internet Protocol (IPv6), also sometimes referred to as IP Next Generation or IPng.
TransNetIETF RFC 4291IP Version 6 Addressing ArchitectureThis 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.
TransNetIETF RFC 4443Internet Control Message Protocol (ICMPv6) for the Internet Protocol Version 6 (IPv6) SpecificationThis standard (RFC) defines the control messages to manage IPv6.
TransNetIETF RFC 793Transmission Control ProtocolThis standard (RFC) defines the main connection–oriented Transport Layer protocol used on Internet–based networks.
Access Internet Subnet AlternativesA set of alternative standards that includes any Subnet Layer method of connecting to the Internet.

Readiness: Moderate

Readiness Description

Two significant or one significant and several 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. 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.
