US: TMDD - NTCIP Messaging

Description:

This solution is used within the U.S.. It combines standards associated with US: TMDD with those for C-C: NTCIP Messaging. The US: TMDD standards include upper-layer standards required to implement center-to-center communications with traffic management systems. The C-C: NTCIP Messaging standards include lower-layer standards that support partially secure communications between two centers as commonly used in the US.

Comm Profile: C-C: NTCIP Messaging

Level	Doc #	Standard	Description
Access		Internet Subnet Alternatives	A set of alternative standards that includes any Subnet Layer method of connecting to the Internet.
Facilities	NTCIP 2306	NTCIP C2C Alternatives	This standard defines alternatives for deploying center-to-center communications using XML directly over HTTPS. This solution works for request/reply exchanges and one-way publications, but not with the subscription/publication model.
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.
Mgmt	W3C WSDL 1.1	W3C WSDL	This standard defines the mechanism for a system to describe the web services that it supports.
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	IETF RFC 9293	IETF RFC 9293 TCP	This document specifies the Transmission Control Protocol (TCP). TCP is an important transport-layer protocol in the Internet protocol stack, and it has continuously evolved over decades of use and growth of the Internet. Over this time, a number of changes have been made to TCP as it was specified in RFC 793, though these have only been documented in a piecemeal fashion. This document collects and brings those changes together with the protocol specification from RFC 793. This document obsoletes RFC 793, as well as RFCs 879, 2873, 6093, 6429, 6528, and 6691 that updated parts of RFC 793. It updates RFCs 1011 and 1122, and it should be considered as a replacement for the portions of those documents dealing with TCP requirements. It also updates RFC 5961 by adding a small clarification in reset handling while in the SYN-RECEIVED state. The TCP header control bits from RFC 793 have also been updated based on RFC 3168.
TransNet		IP Alternatives	A set of alternative standards that allows for the selection of IPv4 or IPv6.

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.
