Base Standards define procedures and rules for providing the funda
17、mental operations associated with communications and information that is exchanged over fixed-point communications links. Profiles define subsets or combinations of base standards used to provide specific functions or services. Profiles prescribe particular subsets or options available in base stand
18、ards necessary for accomplishing a particular function or service. This provides a basis for the development of uniform, nationally recognized conformance. Registration Mechanisms provide a means to specify and uniquely identify detailed parameters within the framework of base standards and/or profi
19、les. The Profiles Working Group is concerned with the methodology of defining profiles and their documentation in Standards Publications. The purpose of this standard is to provide the principles and a classification scheme for the development of NTCIP profiles. This standard also defines aspects of
20、 the formatting and technical content of profiles that conform to this standard. The objective is to facilitate the specification of ITS characterized by a high degree of interoperability and interchangeability of its components. In 1992, the NEMA 3-TS Transportation Management Systems and Associate
21、d Control Devices Section began the effort to develop the NTCIP. Under the guidance of the Federal Highway Administrations NTCIP Steering Group, the NEMA effort was expanded to include the development of communications standards for all transportation field devices that could be used in an ITS netwo
22、rk. In September 1996, an agreement was executed among AASHTO, ITE, and NEMA to jointly develop, approve, and maintain the NTCIP standards. In August 1997, the Joint Committee on the NTCIP formed a new working group to develop a method for organizing class profiles. The Profiles WG first met in Sept
23、ember 1997. After research into how national and international standards organizations combine protocols and standards to address all seven layers of the ISO-OSI Reference Model, the committee adopted the approach defined in the NTCIP Profile Framework. Following that approach, a protocol stack is s
24、pecified by application, transport, and subnetwork profiles. An application profile addresses the application, presentation, and session layers. A transport profile addresses the transport and network layers. A subnetwork profile addresses the data link and physical layers. NTCIP 8003:2001 v01.08 Pa
