[photopress:it_Ipv6.jpg,full,alignright]The first generation of the Internet was wildly successful and, in a sense, it success meant it had to be transformed into the next generation. Professor Wu Jianping with Tsinghua University stressed in a recent interview with Outlook Weekly said, ‘Our nation has quickly caught up in the development of the next generation Internet and has made outstanding achievements. However, if we don’t pay enough attention to these projects, we will lose our voice in this field.’
Professor Zhang Hongke, President of the School of Electronics and Information said currently the network address allocation is not balanced, with more than 70% assigned to North America. Address distribution imbalance has seriously hindered China’s ability to develop an information society.
Currently the commonly used Internet IPv4 adopts 32-figure addresses and has a total of 4.3 billion IP addresses, mostly owned by the United States, leaving less than 800 million addresses to be distributed globally outside of America.
IPv6, a data packet transformation for the next generation Internet, was designed and officially released by the Internet Engineering Task Force (IETF) in 1995 to deal with the rapid development of the Internet. CERNET, Tsinghua University established the first virtual IPv6 test bed in China in 1998, and combined the test bed with 6Bone, which is the test bed of the international IPv6 next generation Internet.
China is the first country to build massive IPv6-only networks, and proposed real source address identification based on IPv6, which ensures the construction of a secured CNGI.
So what are the benefits?
Larger — available for all kinds of electronic devices in addition to computers.
Faster — end-to-end data transmission speed should range between 10Mbps and 100Mbps.
Safer — capable of object identification, user ID authentication, and network access authorization.
More punctual — adopts effective and reliable methods to control the quality of online services.
More convenient — will apply advanced wireless mobile telecommunication technologies.
More manageable — overcome the current difficulty of precise network management.
More profitable — bring benefits to all parties by adopting a new profit-making mode.
