3、tput parameters).Measurement set information, time information, output routing and scheduling information may be completelyor partially pre-defined (initially provided by the supplier but changeable via MML inputs) or fixed (not changeable viaMML inputs). The MML functions described for traffic meas

5、een two consecutive samplings.4 Fascicle X.7 - Rec. Z.3364.2.1 Measurement set informationMeasurement set information consists of one or several selected measurement types with defined objects(object lists) and measurement type dependent parameters (e.g. sampling interval, number of events of a cert
6、aincategory, destination codes, etc.).Note that for traffic measurement administration purposes measurement types are fixed at a given moment intime and they cannot be created, deleted or changed by MML commands; these measurement types may be changedonly later by supplier releases according to new
7、requirements. It is recognized that administrations may require MMLfunctions to administer measurement types, grouping predefined entities of object types. Such functions should beconsidered as system extension and upgrade functions and, therefore, they should belong to the system controlfunctional
8、area. However, due to the fact that system control functions will not be inserted in the presentRecommendations, they are described hereafter.4.2.2 Time informationMeasurements of types A and B may involve continuous recording or recording on predetermined days(recording days).For measurements perfo
9、rming continuous recording only the start data is needed.For recording on predetermined days, these days are determined on a periodical basis (periodicity pattern) incase of measurements of undetermined duration. For measurements of predetermined duration, the recording days aredetermined on a perio
10、dical basis or on a non-periodical basis (dates of recording days). These possibilities aresummarized in Figure 4/Z.336.Time data are defined at three main levels, as shown in Figure 5/Z.336.Measurement level contains information about either: dates of recording days (in case of a non-periodical mea
11、surement). The start and stop date of themeasurement are implicitly defined by the dates of the first and the last recording day. No activationfunction may be needed in this case; periodicity pattern (in case of periodical measurement) of recording and non-recording days.Recording day level contains
12、 information about the start time and stop time for the recording periods within arecording day (e.g. from 09 to 12 and from 15 to 17). No overlap of recording periods is allowed for the samemeasurement.Recording period level contains information about the periodicity of the data collection based on
13、 the resultaccumulation period. The result accumulation period is the time interval within a recording period during which therequired measurement entities are processed and at the end of which results are stored for immediate or later output(e.g. 15 minutes). The result accumulation period can be s
14、horter than the recording period; in that case more than oneset of data is collected for each of the recording periods to be routed toward the output media according to the resultsoutput schedule.Fascicle X.7 - Rec. Z.336 55 Additional information5.1 Measurement output contents and proceduresActivat
15、ion of a traffic measurement causes the output of measurement results with the following procedures.The produced output is routed toward the media specified in the output routing list associated to themeasurement, e.g. printers, magnetic tapes, data links, system output files, etc. The output is mad
16、e according to theoutput schedule.The measurement results output is done according to time data related to the measurement. A measurementresults output is made with the following logical blocks:a) a “begin block” which contains measurement data, parameters i.e. measurement types data, time data,outp
17、ut data and data of interest related to the exchange configuration;b) one or more “result blocks”, one for each result output period, which contain the measurement results;c) an “end block” which contains a general summary about the performance of the measurement, i.e. numberof result blocks, number
18、 of interruptions of the measurement and the causes of the deactivation of themeasurement (scheduled or forced).If during the performance of the measurement, the measurement is suspended (e.g. due to a system crash) themeasurement results output could be continued after the system restart with a new
19、 output of the begin block. Thiscontinuation may be accomplished automatically by the system or by user action. The system should notify the user viaan output if the latter case applies.The relationship between time data for the result accumulation period and time data defining the results outputsch
20、edule is system or even measurement dependent and it is not considered herein.5.2 Simplification of traffic measurement administrationIt is recognized that, for particular applications, there may not be an interest in administering the data base oftraffic measurements. Consequently, the only MML fun
21、ctions needed are activation and deactivation functions.In such cases, in order to ease the operators work, the association between the measurement and the objectsmay be made when activating the measurement itself, provided that the association is unambiguous.6 Glossary of used termsRecordingPerform
