This document defines a subnetwork profile that is a combination of standards intended to meet specific requirements for data transfers to a

14、nd from roadside devices in either a networked or direct-connect environment. This document is an NTCIP Subnetwork Profile Standard. Subnetwork Profile (SP) Standards provide definitions and requirements for the data link and physical layers of a communications stack that follows the OSI Basic Refer

22、RODUCTION The context of the NTCIP is one part of the Intelligent Transportation Systems standardization activities covering base standards, profiles, and registration mechanisms. Base Standards define procedures and rules for providing the fundamental operations associated with communications and i

23、nformation 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 standards necessary for accomplishing a particular function

24、 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 profiles. Within the Joint Committee on the NTCIP, the Prof

25、iles Working Group is concerned with the methodology of defining profiles, and the definition and documentation of profiles in Standards Publications. This document is intended to provide a complete subnetwork profile (SP) that specifies the communications over an asynchronous, half-duplex or full-d

26、uplex dedicated digital circuit. This SP specifies the requirements for an unbalanced connectionless operation. This subnetwork profile can be used with different transport profiles (TP) addressing the network and transport layers with protocols such as UDP or TCP, or it can be used directly with an

27、 application profile (AP) such as the Simple Transportation Management Framework. The objective is to facilitate the specification of ITS systems characterized by a high degree of interoperability and interchangeability of its components. This publication defines a subnetwork profile that is a combi

28、nation of standards intended to meet specific requirements for data transfers to and from roadside devices in either a networked or direct-connect environment. The purpose of this standard is to provide the information necessary to establish a connection using the Point to Multi-Point Protocol (PMPP

29、) via an RS-232 interface. This combination of protocols and standards has been combined in a profile termed SP-PMPP232 within the NTCIP. The SP-PMPP232 is a subnetwork specification and uses protocols and standards to address the Data Link Layer (Layer 2 of the OSI Reference Model) and Physical Lay

30、er (Layer 1 of the OSI Reference Model) to manage connected devices that coexist on a common channel. The SP-PMPP232 supports a variety of upper layer protocols over a common physical implementation. It contains mandatory requirement statements that are applicable to all devices claiming conformance

31、 to this standard. It also contains options and conditional requirements, which may be applicable to a specific environment in which a device is used. In 1992, the NEMA 3-TS Transportation Management Systems and Associated Control Devices Section began the effort to develop the NTCIP. The Transporta

32、tion Sections purpose was to respond to user needs to include standardized systems communication in the NEMA TS 2 standard, Traffic Controller Assemblies. Under the guidance of the Federal Highway Administrations NTCIP Steering Group, the NEMA effort was expanded to include the development of commun

33、ications standards for all transportation field devices that could be used in an Intelligent Transportation Systems (ITS) network. In September 1996, an agreement was executed among AASHTO, ITE, and NEMA to jointly develop, approve, and maintain the NTCIP standards. The Joint Committee on the NTCIP

34、created the Profiles Working Group to develop a method for organizing Class Profiles. The first meeting of the working group was in September 1997. After research into how national and international standards organizations combine protocols and standards to address all seven layers of the OSI Basic

35、Reference Model, the committee adopted the approach defined in the NTCIP Profile Framework. Following that approach, a protocol stack was specified by application, transport, and subnetwork profiles. An application profile addresses the NTCIP 2101:2001 v01.19 Page viDo Not Copy Without Written Permi

A subnetwork profile addresses the data link and physical layers. The NTCIP - Point to Multi-Point Protocol Using RS-232 Subnetwork Profile (SP - PMPP232) is

37、a subnetwork profile for use in center-to-roadside communications.
