32、6014 (1002:CEI)E INTRODUCTION International Standard IEC 61162 is a four-part standard which specifies four digital interfaces for applications in marine navigation, radiocommunication and system integration. The four parts are: IEC 61162-1 Single talker and multiple listeners IEC 61162-2 Single tal

33、ker and multiple listeners, high speed transmission IEC 61162-3 Multiple talkers and multiple listeners Serial data instrument network IEC 61162-4 Multiple talkers and multiple listeners Ship systems interconnection. Part 4 of the standard is subdivided into a number of individual standards with par

34、t numbers in the 400 series. This part of the standard contains the specification of the requirements to an IEC 61162-4 transport profile (T-profile) and also the specification of one implementation, based on redundant Ethernet and Internet protocol functionality. The T-profile is the protocol trans

35、port mechanisms that offer simple message or byte stream transport services to the higher protocol layers (defined in other parts of the standard). In addition, the T-profile also offers services for time distribution and physical network management. The use of Internet and Ethernet protocols offer

36、low cost and high efficiency data transport in any kind of system. However, for safety related applications, certain measures have to be taken to avoid that particulars of office-quality and off-the-shelf technology create safety risks. This part of the standard specifies mechanisms by which a certa

37、in degree of quality of service can be guaranteed from these networks, including the provision of redundancy. Other T-profile documents will be prepared with specifications of the same T-profile require- ments over other transport protocols. This will be issued in the same number series as this stan

38、dard (IEC 61162-41x). Relationship with the other parts of the IEC 61162 series of standards is defined in annex B to IEC 61162-400. Page6 EN61162410:2002 BSI23April2002-26116014 (1002:CEI)E 7 MARITIME NAVIGATION AND RADIOCOMMUNICATION EQUIPMENT AND SYSTEMS DIGITAL INTERFACES Part 410: Multiple talk

39、ers and multiple listeners Ship systems interconnection Transport profile requirements and basic transport profile 1 Scope and object This part of IEC 61162-4 defines the general requirements of the T-profile and three implementations of the T-profile over the Internet V4 (IPV4) protocol suite. Part

40、 400 of this standard defines the relationship between the different protocol levels (T-profile, A-profile and companion standards) and part 401 defines the A-profile, the immediate user of the protocol level defined in this part. The different components of the IEC 61162-4 standard are defined in I

41、EC 61162-400. The T-profile is the specification of the communication services and the communication protocols used by the LNA to implement the A-profile functionality. Basically, the T-profile consists of the following components: a) a transport layer interface (TLI) definition that specifies the s

42、ervices and the semantics that will be available to the application level of the LNA (and in some cases the MAU). This includes data transport as well as time and network management services. The TLI will be general to all T-profiles and is defined in this part 410 of the standard, b) A T-profile pr

43、otocol definition that specifies how the services provided by the TLI and additional time distribution and physical network management services are implemented on the protocol level. This part 410 contains a number of alternative T-profile protocol specifications using the Internet V4 series of stan

44、dards. Additional parts of this standard will address other T-profiles based on other protocol families. Note that the time distribution and network management functionality may or may not include specific TLI services. For some systems this functionality may be interfaced to directly by the underly

45、ing operating system. Note also that time distribution and network management are not strictly speaking transport related protocol functionality. However, the implementation of these services is normally dependent on the transport protocols in use and is, thus, placed in the T-profile part of the st

46、andard. The purpose of this standard is to define and describe the services that will be provided at the transport level interface in a way which is completely independent of the underlying network environment as well as defining one possible implementation of these services over the Internet V4 pro

47、tocols. The separation of service and protocol definitions allows the specification of several different transport profiles, each one dedicated to a specific network environment, and to use the same transport service interface in all cases. Clause 4 defines the transport level services and clause 5

48、describes the transport layer interface through which the services are offered. These clauses define the general, network independent services. Clause 6 defines the transport profile architecture for redundant Ethernet and Internet protocols version 4 (IPV4). Clause 7 defines the architecture for a

49、local area non-redundant Internet network. These clauses define two specific implementations of the T-profile services. Page7 EN61162410:2002 BSI23April2002 8 -26116014 (1002:CEI)E Clause 8 defines a simple MAU-LNA protocol for use over wide area network (WAN) TCP/IP links. This can be used to implement a WAN architecture for the overall system. The WAN architecture is not intended for integrated ship control systems, but can be used for remo
