roadmap identifying NGN management specifications has been published on the
ITU-T SG 4 website.
roadmap will provide an insight into how NGN management will differ from the
management of traditional telecommunication. And as specifications are added
this picture will become clearer, experts said.
The NGN Management Specification Roadmap is an
output of the NGN Management Focus Group, a group sponsored by ITU-T SG 4. The
document identifies the various existing, or work-in-progress specifications
relevant to NGN management. These specifications are not all ITU-T
Recommendations, but also come from other standards making bodies with expertise
in defining management interfaces. For example, the roadmap tags the 3GPP (3rd
Generation Partnership Project) specs for mobile telephony relevant to the IMS
(IP Multimedia Subsystem) management. IMS is expected to be a key building
block for NGN specifications.
additional and important feature of the document is that it provides gap
analysis, identifying areas where standards are still needed, and also
identifies overlapping specifications requiring harmonization.
The aim is for the roadmap to be a living document at this time,
which is part of the reason that it hasn’t been turned into an official ITU
document – like a Recommendation. Another reason for not giving the document
‘normative’ status is so that non-members can enjoy free access to
