2、er defined in 3 to 5.2.2 At the discretion of the Administration concerned, the elements defined in 3 to 5 below can be groupedtogether in a single organizational entity, for example, an International Network Management Centre. This is likely tobe the most convenient and efficient approach where the
3、 level of development and degree of practice of networkmanagement is high. Where such an approach is not possible, or is impractical, international network managementfunctions could be carried out at locations where related activities are performed. 6 offers specific guidance on therelationship betw
4、een network management and network maintenance, and includes consideration for the possiblecombining of organizational elements involved in the two fields of activity.2.3 Irrespective of which arrangement an Administration decides for its international network managementorganization, it must ensure
5、that the functions and responsibilities of a particular organizational element are not dividedbetween two separate locations. Administrations can then issue a list of contact point information (see 7 for guidance)which will give telephone, telex numbers, service hours etc. for each element.3 Network
6、 management planning and liaison3.1 Network management planning and liaison is an element within the international network managementorganization. It is concerned with liaising with other Administrations to develop plans to cater for unforeseen hightraffic levels and any other situation likely to ad
7、versely affect the completion of international calls.3.2 Network management planning and liaison is responsible for the following set of functions:a) liaising with similar points in other Administrations to determine the actions necessary to overcomeunforeseen high traffic levels and other situation
8、s adversely affecting the completion of international calls;b) producing plans to cater for the abnormal traffic levels produced by foreseen national and internationalevents;c) liaising with the restoration liaison officer (RLO) within the Administration concerning networkmanagement plans for failur
9、es and planned outages;d) liaising with similar points in other Administrations to establish the required actions when plans toovercome abnormal situations cannot be implemented;2 Fascicle II.3 - Rec. E.414e) ensuring that the facilities and network management controls required for the rapid impleme
10、ntation ofagreed plans are available and ready for use when required.4 Network management implementation and control4.1 Network management implementation and control is an element within the international network managementorganization. It is concerned with monitoring the performance and status of t
11、he network in real time, determining theneed for network management action, and, when necessary, implementing and controlling such action.4.2 Network management implementation and control is responsible for the following set of functions:a) monitoring the status and performance of the network;b) col
12、lecting and analysing network status and performance data;c) determining the need for the control of traffic as indicated by one or more of the following conditions: the failure or planned outage of an international or national transmission system, the failure or planned outage of an international o
13、r national exchange, congestion in an international exchange, congestion in a distant network, congestion to an international destination, heavy traffic caused by an unusual situation;d) applying or arranging for network management control action, as described in Recommendation E.411, andRecommendat
14、ion E.412;e) liaising and cooperating with similar points in other Administrations in the application of networkmanagement controls;f) liaising with the fault report point (network) 1)within the Administration concerning the exchange ofinformation available at either point;g) liaising with the resto
15、ration control point2)within the Administration concerning failures and plannedoutages;h) disseminating information as appropriate within its own Administration concerning network managementactions which have been taken.5 Network management development5.1 Network management development is an element
16、 within the international network management organization. Itis concerned with the development and introduction of techniques and facilities for the purpose of networkmanagement surveillance and control at the international level, although it may also have similar responsibilities for thenational ne
17、twork.5.2 Network management development is responsible for the following set of functions:a) developing facilities to enable the application of current network management techniques;b) long range planning for the coordinated introduction of new network management techniques andimproved network surv
18、eillance and controls;c) evaluating the effectiveness of current plans, controls and strategies with a view to identifying the need forimproved controls, control strategies and support systems, particularly those which may be required fornew services and the ISDN._1)The fault report point (network)
19、is a functional element in the general maintenance organization (see Recommendation M.716).2)The restoration control point is a functional element in the general maintenance organization (see Recommendation M.725).Fascicle II.3 - Rec. E.414 36 Cooperation and coordination between network management
20、and network maintenance organizationsConsiderable benefit may be obtained by close cooperation and coordination between the network managementorganization identified in this Recommendation and the network maintenance organization identified in the M.700series of Recommendations. For example, reports
21、 of network difficulties received by the fault report point (network) inthe maintenance organization may assist the network management implementation and control point in refining itscontrol action. Similarly, difficulties reported to the fault report point (network) may be explained by informationa
22、lready available to the network management implementation and control point. For this reason, and to take intoaccount the particular operating situation and stage of development of network management within an Administration,some of the functional elements identified in this Recommendation may be lo
23、cated with one of the groupings offunctional elements of the network maintenance organization as outlined in Recommendation M.710.Where it is advantageous to create a separate international management centre containing the elements definedabove, care should be taken to ensure that suitable liaison a
24、nd information flows occur between such a centre and thenetwork maintenance organization.7 Exchange of contact point informationFor each of the three organizational elements in 3 to 5 above, Administrations should exchange contactpoint information. Network management contact points should be exchanged as part of the general exchange of contactpoint information as specified in Recommendation M.93.
