ITU-T RECOMMENDATION SUMMARY
Rec. No. : E.503
Title : Traffic measurement data analysis
Study Group : II - Network Operation
Version : RΘvisΘe
Date of adoption : 1992
Notes :
The aim of traffic measurements is to provide data that can be used by
an Administration for planning, engineering and managing its network.
The resulting measured data can be used to support various activities
as stated in Recommendation E.502. In order to reduce the amount of
data transfer and off-line processing, the exchange or operations
system can be used to make preliminary analyses for purposes of:
- eliminating unnecessary data values;
- replacing missing or wrong values in an approriate way;
- performing simple calculations on the values of the basic
measurement entities to derive characteristic parameter
values of the traffic;
- storing some measured or calculated values, in particular,
traffic data records;
- producing appropriate user friendly report printouts.
For each measurement object, there is a data record in which a certain
number of traffic values are stored. Also, some calculated values,
e.g. moving average, can be stored and updated in this data record
area.
The internal functions of the analysis are not specified in
Recommendation E.503. They depend on the requirements for the output
results which are specified by the Administration. An acceptable
method may be to collect and store the data in real time, either in a
temporary data base file or directly in the traffic data record, and
later perform the calculations and report printout during periods of
low exchange processing activity. Alternatively, the records can be
transferred to an off-line system for processing, to reduce the load
on the exchange.

Order Form for ITU-T Recommendations. An electronic version of this
form is available on ITUDOC (Winword: UPI=ITU-5265; ASCII: UPI=ITU-2488).
