Question 10/II - Traffic measurement requirements on
telecommunications networks
(Continuation of Question 33/II, renumbered and
amended, from the 1985-1988 study period)

Considering

(a) that CCITT has adopted Recommendations E.502, E.503 and E.504
concerning the traffic measurement requirements for SPC (especially
digital) telecommunications exchange;

(b) that the set of basic measurement types specified in
Recommendation E.502 has to be refined and extended to cover
common channel signalling systems, the ISDN and its services;

(c) that traffic measurement requirements for customer access to ISDN
need to be considered;

(d) that the data analysis functions given in Recommendation E.503 and
the list of man-machine functions given in Recommendation E.504
requires definition and extension to cover all traffic measurement
functions;

(e) that close cooperation is required in providing traffic measurement
functions to complement traffic engineering theory, network
management and Quality of Service requirements;

(f) that TMN protocols and common channel signalling systems, such as
CCITT No. 7, will be available for transporting measurement data
between exchanges, network operations centres and other network
entities such as transmission terminals;

(g) that traffic measurement requirements for network entities for
other than telecommunications exchanges need to be considered;

(h) that internal automatic observations in the Public Switched
Telephone Network are contained in Recommendation E.425;

(i) that progress in other Questions may impose other measurement
requirements on telecommunications networks,

What modifications to existing or new Recommendations are required
in order to provide a comprehensive specification on traffic
measurement requirements for telecommunications networks?

Note 1 - Close coordination will be required between this Question and
Questions 8/II (Quality of Service), 9/II (Network Management), 12/II
(Common Channel Signalling System), 16/II (Application of Traffic
Measurements in Telecommunications Networks), 17/II (ISDN traffic
engineering), Study Groups IV and XV on the TMN, Study Group XI on
signalling and exchange design and Study Group XVIII on ISDN.

Note 2 - It should be noted that the new proposed Question 10/II will
require extensive coordination with other CCITT Study Groups and the
activities relating to Quality of Service and network management to
ensure that sound answers to all aspects of the new Question
proposed by administrations are achieved.
