1 Type of Question
Task-oriented Question that should result in new Recommendations.
2 Motivation
Network Terminal Equipment (edge devices) providing the
interworking between broadcaster's local area infrastructure and
wide area networks as specified, for example, in ITU-T
Recommendations J.131 (Transport of MPEG-2 signals in PDH
networks) and J.132 (Transport of MPEG-2 signals in SDH
networks) does not comprise standardized management functions
such as management information base, control channels for
signalled connections and application programming interfaces
(APIs).
Whilst some progress has been made in standards for the
exchange of TV-programme materials, no work has been undertaken
in the domain of management information, interaction channels
for broadband networks and APIs for the network terminals. A
consistent reference architecture of network and management
aspects from the broadcaster's perspective already exists, but
it does not cover the specific solutions required from the
network operator's point of view. In the study period 1996-2000,
Study Group 9 has worked and continues to work on a number of
solutions for the transport of television and sound content over
WANs. As new elements for the transport of television and sound-programmes
are implemented for isochronous and packet-based networks on the
edge of WANs, there is a requirement for the management of these
new elements.
Typical management tasks should be supported such as:
- management information base of network terminal
equipment for interworking between local area and wide area
transmission schemes;
- management APIs for such network terminal equipment;
- control channel function for signalled connections;
- management of end-to-end service over the whole
transmission chain.
3 Questions
- What new Recommendations are required for the
specification of management information, interaction
channels and APIs to facilitate the management of network
terminal equipment for the contribution and primary
distribution of television and sound-programmes?
- What will be the impact of the broadcaster's
reference architecture on Study Group 9
Recommendations?
4 Expected results and anticipated target dates
Depending on the contributions that will be received, and on
the progress in the work of the appointed Rapporteur, it is
expected that this Question will result in one or several new
Recommendations before the end of 2002.
5 Relationships
Cooperation with Study Groups 4, 7 and 15 is needed in the studies.
