[Keynote Address] From CERNET to CNGI-CERNET2, then to the Future Internet
Xing Li (Tsinghua Univ.) IA2009-43
Abstract (in Japanese) (See Japanese page) 
(in English) The Internet has been becoming an important infrastructure of network society. Recently, the research on future Internet increases the importance in world wide scale. In this presentation, the author shares the experience of the design, construction and the operation of China Education and Research Network (CERNET), the second generation China Education and Research Network (CNGI-CERNET2) and presents the prospective for the future Internet.
CERNET is the first nation wide TCP/IP network in mainland China, it grows from 10 Pops to 38 Pop covering all the provincial capitals connected via 2.5Gbps to 10Gbps lambdas. There are about 1,600 universities and institutes connected to CERNET and the number of the end users is about 20 million. The major challenges of CERNET are the scalability, the security and the charging model.
CNGI-CERNET2 is the first national wide IPv6 network in mainland China, it has 25 Pops connected via 2.5Gbps to 10Gbps lambdas. There are about 200 research universities connected to CNGI-CERNET2 and the number of the end users is about 1.5 million. The unique features of CNGI-CERNET2 are: it is an IPv6 single-stack network; it consists of equipment from multiple vendors and it is a multiple autonomous system network. CNGI-CERNET2 also supports the new technology trials, for example IPv4 over IPv6 and source address validation.
Based on the experience of CERNET and CNGI-CERNET2, the author summarizes the challenges which the future Internet must address. They are: the routing system scalability, the security, the quality of service, the charging model, the mobility and the transition. Some examples are also discussed in the presentation.
