A roadmap identifying NGN management specifications has been published on the ITU-T SG 4 website.

The 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.

An 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 it.
