13、O member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, gove

14、rnmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC D

15、irectives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member b

17、gy, Subcommittee SC 6, Navigation and ship operations.iv ISO 2013 All rights reservedBS ISO 16425:2013ISO 16425:2013(E)IntroductionThis International Standard gives guidelines relating to such matters as the communication network-system architecture, data requirements, administration, operation, com

18、missioning, inspection and testing.This International Standard also takes into account differences between shipboard communication networks and networks that are used outside of ships, and stipulates requirements and the like in clauses relating to matters unique to shipboard use.Until now, there ha

19、ve not been comprehensive guidelines for connecting devices provided by many different manufacturers to a network via generic means, and this has impeded the wider use of shipboard networks.This International Standard will make it possible to provide guidelines for all aspects of communication netwo

20、rk-system design, commissioning, inspection, testing and operation, and improve convenience to all involved parties, including manufacturers, engineering firms, shipbuilders, and shipping companies.This communication network for shipboard equipment connects equipment, and shares information gathered

21、 from shipboard equipment and systems via a network. This communication network is connected to the navigational equipment network and engine-control network via an appropriate gateway.The independence of such a network is ensured by using a gateway.This network is intended for information sharing a

22、nd is not directly related to safety of navigation. Also, it is not a system targeted for classification rules.Additionally, Annex A is attached to provide detailed examples of technical information that serve as guidelines for some difficulties caused when the information network system is designed

23、.NOTE Requirements for wireless communication systems, which serve as an effective method of onboard wireless communication, is specified in IEEE 802.11, and national laws are established based on the aforementioned IEEE in each country. Different frequency and output range are allotted by each coun

24、try, and regulations exist for such frequencies and ranges in some countries. Given the circumstances, it is possible that wireless communication systems cannot be used when calling at a port. Therefore, wireless communication systems are outside the scope of this International Standard. ISO 2013 Al

27、peration, and installation.The new guidelines specifically include: redundancy if necessary for a shipboard communication network system; network administration that does not require experts; physical as well as logical security; and network installation.2 Normative referencesThe following documents

38、 Pair5 Network system architecture5.1 Network system designThe design of this network system shall give due consideration to such matters as the compatibility of the various devices in the network as a whole, and data transmission (amount of information, latency, and routes). Consequently, a network

39、-system designer should have a grasp of the overall system, comprehensive knowledge, and consideration for shipboard use.When designing the network system, the effective data volume and network load factor should be pre-calculated when the network media are under maximum load. In addition, provision

40、 should be made for further network expansion and increase of the data traffic. ISO 2013 All rights reserved 3BS ISO 16425:2013ISO 16425:2013(E)The design shall also foresee the various potential system states, including initial state, failure state, and normal state, in order to define which commun

41、ication is to be granted in various failure scenarios.The network diagrams shall be equipped on the vessel. When the network design is changed, the network-system designer shall retest the network and update the network diagrams.As a data requirement, it is extremely vital to consider such factors a

42、nd to prevent ship equipment connected to the network that does not send or receive data from being excessively impacted.Data requirements are specified in 6.2 and 6.3.5.1.1 Scope of network system architectureThis network system shall be designed specifically for ships, with the purpose of sharing

43、information between shipboard devices. It shall be independent from navigational equipment networks and engine-control networks.The scope of the network systems architecture is not limited to the bridge. It extends to all key locations on the ship.The network shall not operate (control) the ships na

44、vigational equipment, however it should allow monitoring of navigational equipment.Figure 1 shows a sample network-architecture scope. The typical implementation of the contents provided in this International Standard is specified in Annex A.NOTE The following are some examples of areas within the s

45、cope of the network-system architecture:-Navigation Bridge / Control Centre;-Captains Office;-Officers Office;-Officers Mess;-Captains Cabin;-Officers Day Room;-Engine Control Room;-Engine Room;-Cargo Control Room;-Field / Cargo.5.1.2 Network system separationThe network system shall be separated fr

46、om other networks by an L3 switch so that it will not be adversely affected by failures on other networks. The routing and filtering rules should be configured appropriately on the L3 switch for traffic and security. For more advanced security, a firewall for the upper layer may be used.5.1.3 Networ

47、k divisionThe network shall be divided into sub-networks (the broadcast domains) depending on the types of information handled, in order to control traffic and ensure security. In order to ensure the security and the control of traffic, the network shall be logically segregated to form sub-networks,

48、 depending on the 4 ISO 2013 All rights reservedBS ISO 16425:2013ISO 16425:2013(E)type of information to be handled. Each network should be designed so that network soundness can be maintained at all times, including when failures occur on other sub-networks.NOTE The following are some examples of s

49、ub-networks formed from the main network:-Navigational data collection sub-network;-Engine data collection sub-network;-Shipboard telephone sub-network;-Imaging sub-network;-General shipboard document-review sub-network.5.1.4 Traffic divisionThe network shall be built to minimize the collision domain (the scope of packet collisions), and appropriately divide the broadcast domain (the domain reached by broadcasts).The bandwidth used by the core network shall be designed appropriately, and a logical network system sh
