Annotation of standard text IEC 61162-450-ed.2.0 :
IEC 61162-450:2018 is also available as IEC 61162-450:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61162-450:2018 specifies interface requirements and methods of test for high speed communication between shipboard navigation and radiocommunication equipment as well as between such systems and other ship systems that need to communicate with navigation and radio-communication equipment. This document is based on the application of an appropriate suite of existing international standards to provide a framework for implementing data transfer between devices on a shipboard Ethernet network. This document specifies an Ethernet based bus type network where any listener can receive messages from any sender with the following properties. - This document includes provisions for multicast distribution of information formatted according to IEC 61162-1, for example position fixes and other measurements, as well as provisions for transmission of general data blocks (binary file), for example between radar and VDR, and also includes provisions for multicast distribution of information formatted according to IEC 61162-3, for example position fixes and other measurements. - This document is limited to protocols for equipment (network nodes) connected to a single Ethernet network consisting only of OSI level one or two devices and cables (Network infrastructure). - This document provides requirements only for equipment interfaces. By specifying protocols for transmission of IEC 61162-1 sentences, IEC 61162-3 PGN messages and general binary file data, these requirements will guarantee interoperability between equipment implementing this document as well as a certain level of safe behaviour of the equipment itself. - This document permits equipment using other protocols than those specified in this document to share a network infrastructure, provided that it is supplied with interfaces which satisfy the requirements described for ONF. - This document includes provisions for filtering of the network traffic in order to limit the amount of traffic to manageable level for each individual equipment. This document does not contain any system requirements other than the ones that can be inferred from the sum of individual equipment requirements. An associated standard, IEC 61162-460, further addresses system requirements. This second edition of IEC 61162-450 cancels and replaces the first edition published in 2011 and Amendment 1:2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) network traffic filtering based on IGMP snooping added; b) network traffic balancing added; c) new encapsulation of IEC 61162-3 PGNs added; d) new alternative for binary file transfer added: TCP/IP based on Annex H of IEC 62388:2007 on radars; e) general authentication tag "a:" added to support managing of cyber security risk. IEC 61162-450:2018 est disponible sous forme de IEC 61162-450:2018 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis ledition precedente. LIEC 61162-450:2018 specifie les exigences dinterface et les methodes dessai de la communication a grande vitesse entre les materiels de navigation et de radiocommunication embarques, et entre ce type de systemes et dautres systemes de navigation qui necessitent de communiquer avec les materiels de navigation et de radiocommunication. Le present document repose sur lapplication dune serie appropriee de normes internationales existantes visant a definir le cadre de mise en ouvre du transfert de donnees entre les dispositifs sur un reseau Ethernet embarque. Le present document specifie un reseau de type bus Ethernet dans lequel un recepteur peut recevoir des messages dun emetteur avec les proprietes suivantes. - Le present document comporte les dispositions en matiere de distribution multidiffusion des informations mises en forme selon lIEC 61162-1 (releves de position et autres mesurages, par exemple) et en matiere de transmission de blocs de donnees generales (fichier binaire) entre un radar et un VDR, par exemple. Enfin, il contient les dispositions relatives a la distribution multidiffusion des informations mises en forme selon lIEC 61162-3 (releves de position et autres mesurages, par exemple). - Le present document se limite aux protocoles pour les materiels (nouds de reseau) connectes a un seul reseau Ethernet compose uniquement dun ou de deux dispositifs et cables de niveau OSI (Infrastructure de reseau). - Le present document fournit les exigences relatives aux interfaces de materiel uniquement. En specifiant les protocoles de transmission des sentences IEC 61162-1, des messages PGN IEC 61162-3 et des donnees generales de fichier binaire, ces exigences assurent linteroperabilite entre le materiel mettant en ouvre le present document, ainsi quun certain niveau de comportement sur du materiel lui-meme. - Le present document permet au materiel utilisant dautres protocoles que ceux quil specifie de partager une infrastructure de reseau comportant des interfaces satisfaisant aux exigences decrites pour lONF. - Le present document comporte les dispositions en matiere de filtrage du trafic reseau afin de limiter la quantite de trafic a un niveau que chaque materiel individuel peut gerer. Le present document ne comporte aucune exigence systeme autre que celles qui peuvent etre deduites de la somme des exigences du materiel seul. La norme connexe IEC 61162-460 aborde les exigences systeme. Cette deuxieme edition de lIEC 61162-450 annule et remplace la premiere edition parue en 2011 et lAmendement 1:2016. Cette edition constitue une revision technique. C
