Andrew Nunn, Convener ITU-T JCA-HN (Joint Co-ordination Activity – Home
Networking)
Home Networking in ITU-T
An overview of the Home Networking studies in ITU-T
and of the Joint Co-ordination Activity which has been
set up to harmonize these studies across the various
ITU-T Study Groups and seek co-operation with
outside Home Networking bodies
Submission Date:
July 1, 2008
Highlight of Current Activities (1)
• Work is currently underway on a total of 10 Home
Networking related Recommendations in ITU-T SGs 5, 6, 9,
15, 16 and 17
• ITU-T SG15 have invited comment from a number of
external bodies on their new draft Recommendations G.hnta
- “Generic Home Network transport architecture & G.hn “Next generation home networking transceivers”
• SG15 is also co-operating with ISO/IEC JTC1 SC25 WG1 on
the harmonization of their emerging Home Network
management standards with Broadband Forum (ex DSL
Forum) TR-69. In addition, SG15 are contributing to the
ISO/IEC JTC1 SC25 PTTI on Home Networking terminology

Highlight of Current Activities (2)
New draft Recommendations are being developed on:
• Electromagnetic environment in Home Networking
• Network noise models due to Home electromagnetic environment
• Common facilities for telecommunications elements inside buildings
• Optical fibre cable functions for indoor applications
• IP over IEEE 1394 as a function of protocol conversion for cable-based
Home Network
• Generic Home Network Architecture
• Next generation Home Networking Transceivers
• Generic Home Network Architecture with support for multimedia services
• Architecture and functional requirements for Home Network supporting
IPTV
• Authorization framework for Home Network
3
Strategic Direction
• ITU-T continues to develop a number of Recommendations in the
Home Networking area
• The JCA-HN continues to encourage co-operation with other
Home Networking bodies
4
Challenges
• With the ever growing number of computers, audio/video
devices and home automation products etc. deployed in
the home environment, Home Networking is becoming
increasingly important. The main challenge is how to bring
together the many standards bodies working on Home
Networking in order to develop global standards in this
area which would bring benefits to manufacturers,
Network Operators and consumers alike
• Network Provider: Responsibility ends at UNI
Customer: Expect QoS at service end point (STB)
-> Gap between formal responsibility and customer’s
expectation
5
Next Steps/Actions
• Continue to encourage members to contribute to Home
Networking studies in the ITU-T
• Continue to encourage co-operation with other Home Networking
bodies
