                          TRAFFIC MEASUREMENT ADMINISTRATION
         1      Introduction
               Traffic measurement administration includes the scheduling and  control  of
         traffic data collection,  and  production  of  reports  for  analysis.  The  data
         collected by means of traffic measurements performed by the exchange is output in
         a form suitable for on-line or deferred analysis.
               It may be useful to consider the concept of a generic  Traffic  Measurement
         System (TMS) for purposes of administering traffic measurements.  Such  a  system
         may  comprise  elements  of  an  exchange  working  in  conjunction   with   some
         combinations of remote data processors  and  associated  devices  for  output  of
         measurement reports.
               In  order  to  administer  traffic  measurements,  a  series   of   related
         man-machine activities (referred to as "tasks") will need to be performed through
         one  or  more  man-machine  interfaces,  and  supported  by  appropriate   system
         functions. Details are given below.
               The traffic measurement output should contain the  measured  data  together
         with  reference  information  about  network  conditions  at  the  time  of   the
         measurement which would assist in the data analysis, for example  the  number  of
         blocked devices on a route or temporary alternative routing in effect.
         2      List of tasks
               The following list of tasks is not intended to  be  complete;  however,  it
         aims to cover the essential activities in the area of  the  traffic  measurements
         administration. The TMS will provide functions to support these tasks:
               a)  to create new measurements or measurement components and to modify old
                  ones, by selecting the measurement types, schedules, object  identities
                  and parameters of the measurements (WHAT, WHEN and HOW to measure);
               b)  to delete measurements or measurement components which are  no  longer
                  useful;
               c)  to define output routing and scheduling of measurement  results  (WHEN
                  and WHERE the result will be output);
               d)  to activate and/or to deactivate the scheduling  of  the  measurements
                  that have been previously defined;
               e)  to retrieve the required categories of data related  to  the  existing
                  measurements.
         3      List of system functions
               To support the man-machine  tasks,  the  TMS  should  offer  the  following
         functions:
               a)  a menu of traffic measurements;
               b)  scheduling of traffic measurement execution and results output;
               c)  management of measurement's description data;
               d)  retrieving of measurement's description data.
         4      Man-machine functions
               A preliminary list of man-machine  functions  needed  to  control  the  TMS
         functions previously given is listed below; the complete  specification  of  such
         functions appears in the Z-Series Recommendations:
               -   create a measurement;
               -   create a measurement set;
               -   create an object list;
               -   create a time data list;
               -   create an output routing list;
               -   create a results output schedule;
               -   modify a measurement;
               -   modify a measurement set;
               -   modify an object list;
               -   modify a time data list;
               -   modify an output routing list;
               -   modify a results output schedule;
               -   delete a measurement;
               -   delete a measurement set;
