Lacks in current standards
 In the following slides:
 This colour means: QoS parameter covered in one existing
standard from the end-user point of view
 This colour means: QoS parameter covered in one existing
standard for measurement method
 Therefore work is needed everywhere it's blue

EG 202 009 revision
 Beside the parameter review, provide
guidance to the user needs analysis for the
definition of appropriate classes of services
(Part 1) see ITU-T G1010
 In addition to the end-to-end QoS concept
(same parameter whatever the bearer
network) define the perimeter for QoS
parameter measurement.
