Numerical Addressing Space Management Team (NASM) Working Group
Scope of Work: NASM is a working group of the
Video Development Initiative (ViDe)
and is responsible for the management of ViDeNet numerical
address space, which is currently utilizing the Global Dialing
Scheme (GDS). This group maintains the GDS numerical address
space and supporting routing schemes, including E.164int integration,
hierarchical and flat structures, with particular emphasis on
the root level and top tier architectures. Of particular importance
is the alignment of existing H.323 addressing to E.164-like structures,
in order to prepare the way for an eventual migration toward
full DNS-based dialing via h323 URL, ENUM and related numerical
address translation schemes. This group is responsible for the
allocation of ViDeNet address space to lower tier domains. In
particular, the group identifies which organizations and research
networks will be responsible for managing national gatekeepers.
The group's operational responsibilities include the review of
new ViDeNet membership requests, assignment of address space,
and configuration of the top-level gatekeeper meshes. Members
of this group will have root administrative access to the ViDeNet
management system and all top-level gatekeepers and will ensure
the integrity of data registered with ViDeNet. All address assignments
made by this group are final.
NASM is not chartered to make changes to the GDS dial plan. Dial
plan changes and other architectural recommendations from NASM
require the support of the ViDeNet Zone Administrators and the
approval of the ViDe Steering Committee.
NASM members are required to have clearance from their employer
to dedicate 5 hours per week to maintaining the hierarchy, reviewing
peering requests, troubleshooting and performing system maintenance.
Additionally, responsibilities include promotion of the service
to constituencies and attending regular meetings.
NASM members may be required to provide hosting services for root
gatekeepers, including 7x24 monitoring, Internet connectivity,
power and rack space. Members will be required to provide host
and gatekeeper application administrative access to the team
in order to facilitate shared, remote management of root clusters.
IMTC Liaison: A significant goal of the ViDeNet
project is to expand ViDeNet membership into the private sector
to include carriers, service providers and technology developers.
Greater private sector participation will help the research and
private sectors speak with a unified voice in order to raise
the level of awareness within the ITU-T and the IETF about the
importance of dial plans and numbering schemes with respect to
video and voice over IP. Goals include the creation of an environment
which stimulates the submission of contributions to standards
bodies on dial plan architectures, increasing the level of participation
in standardization activities, and increasing the level of dialog
about dial plan architectures.
Toward this end IMTC and ViDe will jointly provide representatives
to NASM. This will be an aid to ensuring the broadest possible
perspectives. Further, it will ensure that routing nodes are
deployed across research networks and the public Internet, ensuring
the greatest possible service resiliency.
Membership Guidelines: Project team members are
appointed by the Working Group Chair. All members of this group
must be zone administrators or representatives from active ViDeNet
zones. Membership terms are from January 1 to December 31 of
any calendar year and terminate automatically, with the option
to request renewal. IMTC is responsible for selecting its representatives,
ensuring a fair process for that selection, and presenting its
selected representatives to the Working Group Chair. The Working
Group Chair is expected to accept the IMTC’s selected representatives
unless some reasonable objection is identified, in which case
the IMTC will propose alternate representatives.
