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.

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.

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.

W3C WSDL
|
This standard defines the mechanism for a system to describe the web services that it supports.

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.

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.
