Bounded secured managed domain
ISO 21217 "ITS communication architecture" introduced the concept of the ITS station as a - bounded, - secured, - managed domain.
Adopted by ETSI in EN 302 665.

Communications & Applications
Communication protocols are within the Access Layer, the Networking & Transport Layer, and in the Facilities Layer.
C-ITS application protocols are in the Applications entity, and partly in the Facilities layer
The ITS station is managed locally by protocols located in the Management Entity
The Security Entity is providing protocols to secure communications, applications, and physical units.

Conformance & Interoperability Testing
The basis for conformance and interoperability testing was set up by the ETSI guide taking into account base standards from ETSI and ISO.

International Testing Centre for C-ITS
ETSI CTI is the centre for conformance and interoperability testing!
Experienced in writing test specifications for base standards from all interested SDOs
Experienced in building test platforms, e.g. the C-ITS test framework developed under EC mandate M/453
Experienced in running interoperability trials
See presentation of CTI for details.

Next steps
Extension of the existing conformance validation framework at ETSI CTI, which was originally created to test ETSI standard implementations related to road safety, e.g. GeoNetworking, CAM, DENM.
The extended framework will support C-ITS standards developed at ETSI
the set of CALM standards developed at ISO TC204 WG16. Initial implementations will be in support of ISO 21218, ISO 29281-2, ISO 24102-5, 24102-4,
C-ITS application standards currently under joint development at ISO TC204 WG18 / CEN TC278 WG16
Stakeholders are implementing ISO / CEN protocols and ETSI protocols in a single ITS station, and plan to use the extended conformance validation framework.
A subsequent step will be interoperability testing of equipment supporting the full scope of C-ITS.
