The Number of Broadband Access Will
Overrun that of Narrow Band in China
ITU-T @
45.5% of Internet users have been used ADSL, the proportion of broadband
subscribers will exceeded 78% of total Internet users if the number of LAN
users is included in count.

Network Development Entering New Stage
ITU-T
@ IP----dominant traffic
q Accumulative call duration of domestic long distance and Int’l
communications: VOIP beyond TDM.
q Bandwidth of trunk occupied by IP traffic has been overtake
traditional TDM fixed and mobile.
@ Broadband ----new focus for Competition on service
q China’s cities/towns with population high density are in favor of
broadband deployment. Internet users to use broadband access
will more than that narrow band after a few years.
@ Mobile----entering 3G era
q Mobile frequency resource is scarcer in cities. Mobile operators in
China will select 3G as start point of new competition.

Network Development Entering New Stage
ITU-T @ Network----changes to next generation
q Problems such as IP scalability, QOS and security are going
more and more serious.
q Internet entering the domain to carry real time services has
to confront challenge on QOS,while telecom network endures
the pressure from broadband services.
q NGI and NGN---New generation network goals respectively for
Internet and telecom network.
q The evolution vs. revolution on network development
debates come in. Should the network be ''connectionoriented'' or ''connectionless''?

NGN & NGI
ITU-T
@ NGI is following the thought-way of
Internet. Commonly believe that IPv6
is one of the character of NGI,
besides, several protocols need to be
extended.
Applications
NGN
NGI
@ NGN adopts the Internet technique
(IPv6 or IP friendly protocol) rather
Computer
than its mechanism, It is not any
circle
longer that network is stupid and
complex functions is pushed to
terminal. Network must be active and
smart in resource assignment and
service delivery aspects.

NGN & NGI
ITU-T
@ NGN and NGI co-develop in the competition between them
by learning technique each other
@ Although NGI is not the unique solution to NGN, but NGI can
see as a main component of NGN.
@ It is relatively easy to develop NGN with NGI as start point

Traits of CNGI
ITU-T
@ CNGI attaches importance to QOS architecture and
technologies.CNGI takes care of wireless and mobile service
and pay attention on administrable network and controllable
service with the object of commercial application.
@ Research and trial coordinating NGI and NGN technology
development direction was put forward and encouraged by
CNGI project.
@ CNGI develops network hardware,software and application to
possibly use to NGN.
@ CNGI explores the road to converge NGI and NGN.
