Introduction
• “Home network” and “Home gateway” have been
“existing” for long time.
• But, recently, these words have been widely accepted
by the following popularity
– Technologies
• Infrastructure: Internet, especially broadband services by fixed fare
• Terminal: Networked home appliance
– Lifestyle using network by end users
• Easy networking (enhancement of usability)
• Secure and reliable
– Various contents with right management

Study on home network in
ITU-T
•Several SGs are interested in home networks from several points of view.
•Studies in each SG has been started.
•In the next study period (2009-2012), it will be one of main topics
SG9: Home network based on
Cable network (J.190)
SG16: Home network architecture
(Control) (H.gha)

Home network configuration
and services
• Physical home network configuration is typically “Tree” or
“Star” centralized by gateway, such as home gateway.
• Logically, terminals or home appliances are categorized into 4
planes, such as PC, Phone/fax, AV, and living planes.
