- The list of operator jobs and the list of system functions to be

- .sp 1P
- .RT
- .PP
- Network management is the function of supervising the network and taking
- action to control the flow of traffic so as to ensure the maximum
- utilization of the network in all situations. The objective is to enable as
- many calls as possible to be successfully completed. In its current scope,
- Network Management doesn't address the aspects of managing traffic on portions
- of the network that are leased or under the control of network customers.
- .PP
- According to CCITT Recommendations\ E.410 through\ E.414, E.502, Q.542
- and\ Q.544, Network Management requires the performance of a certain number
- of activities to detect abnormal network conditions and to initiate the
- execution of corrective actions and/or controls. The general scenario of
- Network
- Management activities can be described through the involved information
- flow as depicted in Figure\ 1/Z.337. Network Raw Data related to traffic
- parameters and the status (i.e.\ level of overload, out of service conditions,\
- etc.) of the
- Network Elements can be processed to provide Network Management Parameters,
- using the Network Reference Data which are necessary to calculate Network
- Management Parameters. The Network Raw Data are produced from Network
- Management Elements.
- .PP
- Network Management Parameters, describing the current network status and
- performance, can be related to some threshold values (representing the
- boundary between normal and abnormal behaviour) in order to detect abnormal
- conditions.
- .PP
- Abnormal Condition Reports, Network Management Parameters and other
- information (from telephone operators, work centres, news media, etc.)
- are used to identify the origin of the problem and, as a consequence, to
- decide the
- proper actions to be taken or the most suitable controls to be activated.
- .PP
- Network problem identification and consequent corrective actions can be
- handled manually or automatically by an \*Qexpert\*U system which is capable
- of performing the functions of abnormal condition detection, problem analysis
- and problem solving. All the activities carried out for Network Management
- can be handled by the operator supervision.
- .PP
- Furthermore, for cooperation, coordination and planning purposes,
- Network Management Reports could be distributed to other operating centres,
- to higher authorities,\ etc.
- .PP
- Depending on each Administration and network organization, Network
- Management activities can be partially or totally performed at exchange
- level or concentrated in one or more Network Management Centres.
- .PP
- Figure 2/Z.337 contains an example of how the general scenario can be applied
- to a particular operating organization. In this example, the functions
- shown for the Network Element and Network Management Operations System
- are
- performed by the system under operator control.
- .bp
- .PP
- Considering the Network Management scenario and the operator
- activities (listed in Annex\ A to this Recommendation) three different
- sub\(hyareas can be recognized:
- .RT
- .LP
- \(em
- Network Management Data administration;
- .LP
- \(em
- Network Management Controls administration;
- .LP
- \(em
- Network Management Data Distribution administration.
- .PP
- Only the sub\(hyareas for Network Management Data administration is covered
- by the present Recommendation. The remaining two sub\(hyareas, namely
- Network Management Controls administration and Network Management Data
- Distribution administration are left for further study.

- According to the division of Network Management activities in three sub\(hyareas
- as stated in \(sc\ 2, three different models, as indicated in the
- following, have to be developed:
- .RT
- .LP
- \(em

- \fINetwork Management Data administration model\fR
- .sp 9p
- .RT
- .PP
- Network Management Data administration sub\(hyarea concerns the
- operator activities for managing the set of information necessary to monitor
- the network status and performance. This information can be routed toward
- proper display and/or storage devices in the Network Management Centre or
- passed to remote Administrations under operator control.
- .PP
- Data administration is applied to the following data:
- .RT
- .LP
- \(em
- Network Raw Data;
- .LP
- \(em
- Network Management Parameters;
- .LP
- \(em

- .sp 1P
- .LP
- 3.2.1
- \fINetwork Raw Data\fR
- .sp 9p
- .RT
- .PP
- Network Raw Data describe, for each network management element, the current
- operating conditions (e.g.\ exchange load, number of in\(hyservice
- circuits,\ etc.) and traffic behaviour (e.g.\ number of seizures for circuits
- sub\(hygroup).
- .PP
- Network Raw Data are administered by the MML functions for Traffic
- Measurements Administration, therefore they are not considered in the Network
- Management functional area.
- .RT
- .sp 1P
- .LP
- 3.2.2
- \fINetwork Management Parameters\fR
- .sp 9p
- .RT
- .PP
- Network Management Parameters describe the network status and
- performance in terms of entities (as indicated in Recommendation\ E.411) and
- Network Management Objects.
- .PP
- Network Management Objects are the set of Network Elements subject to measurement
- for Network Management purposes.
- .PP
- One or more Network Management Objects can be grouped as origin and/or
- destination objects to define traffic flow; the Network Management Objects
- are hierarchically presented below:

- \(em
- exchange group;
- .LP
- \(em

- .LP
- \(em
- circuit group;
- .LP
- \(em
- circuit sub\(hygroup.
- .PP
- Network management monitoring and control of circuit groups and
- circuit sub\(hygroups can only be performed via an exchange.
- .PP
- In Figure 3/Z.337 is represented, as an example, a Network Management Parameter
- in terms of the entity \*Qanswer/seizure ratio\*U for traffic handled by
- a circuit sub\(hygroup and forwarded to a set of exchanges characterized
- by the

- The list contains possible MML functions for Network Management

- .PP
- This list is not mandatory nor complete, it may vary according to
- administration needs, telecommunication network levels, regulatory needs,\ etc.
- .PP
- These MML functions do not represent the actual command structure of any
- real implementation of the man\(hymachine interface. Each of the MML functions
- identified can be implemented by providing one or more separate distinctive
- commands or several MML functions could be implemented by using a single
- command.
