Abstract:

With the world's second-largest and fastest-growing Internet user population, more net-citizen share an IPv4 address in China, it is indispensable to update to IPv6.

VOIP has become dominant in long-distance voice service. The proportion of int'l VOIP in China was as 4 times as the world level. Internet entering the domain to carry real time services has to confront the problems such as QOS and security. IPTV needs a manageable IP network to carry.

China's cities/towns with population high density are in favor of broadband deployment especially FTTB/FTTZ. Chinese broadband users download video content in greater percentages than users in the US. P2P file share traffic now is single largest traffic type by volume on the backbone network. The carriers press for scalable network bandwidth and loss of revenues for emerging traffic. Internet was facing challenges on convergence with telecommunications and broadcasting. But over-lapping responsibility and different goals of broadcast and communication regulation to restrict triple play popularization should be resolved.

China's mobile packet data subscribers accounted for 25% of total mobile subscribers. The 3G development will further impel mobile Internet development. TD-SCDMA used TDD mode is flexible in uplink or downlink bandwidth allocation and thus especially suits to asymmetric services such as access to Internet.

The development history of the Internet itself is an innovative course. In order to enable new paradigm shifts that preserves and expands opportunities for innovation and economic growth. It wills to be seen the evolution or revolution of Internet protocol are required, but more important is to build an innovation environment.

NGI / NGN trial in China is in process of underway. At present CNGI (China's next generation Internet demonstration network project) is the most large-scale IPv6 experiment network in the whole world. It is other than NGI experiments carried on in overseas, because of the active participation of major telecommunication operators in China, CNGI has paid much more attention for to research on QOS architecture and technologies and to support for wireless and mobile business development.
