@ 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
@ 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 ''connection-oriented'' or ''connectionless''?
13
ITU-T
Workshop on IPv6Geneva, 22-23 June 2005
NGN & NGI@ 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.
@ NGN adopts the Internet technique (IPv6 or IP friendly protocol) rather than its mechanism, It is not any 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
@ 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
