Question 16/II - Application of traffic measurements in
telecommunication networks (continuation of Question 30/II, amended,
of the 1985 1988 study period)

Considering

(a) that traffic measurements have different purposes, for forecasting,
dimensioning and monitoring;
(b) that measurements may be taken on a continuous or non-
continuous basis;

(c) that new routing techniques and service protection methods have
been recommended;

(d) that existing telephone network has to respond to new traffic
demands with other traffic characteristics than those of traditional
telephone traffic;

(e) that for voice and non-voice services in existing networks further
work in determining traffic measurement analysis procedures is
required;

(f) that for the service mixture in the ISDN appropriate traffic
measurements have to be defined;

(g) that traffic measurements on a destination basis are gaining more
interest;

(h) that for planning of the ISDN knowledge of traffic profiles
according
to the service mix is needed,

the following is to be studied:

1. What new traffic measurement analysis procedures are required?

2. What evaluation procedures should be recommended to obtain
relevant traffic parameter values (carrier traffic intensity, grade of
service, etc.) from the measured data?

3. What improvements to Recommendation E.500 can be made?

4. What are typical traffic profiles and the characteristics of other
traffic
parameters of the services of the ISDN separately or heterogeneously
mixed with telephone traffic?

Note - Studies under this Question require close coordination with
Question 10/II (Traffic measurement requirements on
telecommunications networks).
