In April, Beijing has been hot, the rain danced, and the street occasional short shirt longprints are quietly adjacent. The same hot places also include the venue of the Beijing International Convention Center, but this kind of hot more comes from the industry's attention to the next generation network, the attention of China's CNGI (China Next Generation ".
The background of this conference was in 2003 China's eight major parties jointly launched a CNGi China's next-generation Internet demonstration project, which will build an IPv6 network throughout the country at the end of 2005. They will also become one of the world's largest IPv6 networks. The theme of this conference is: "CNGI is working China IPv6 Engine". The meeting gathers foreign experts, manufacturers representatives, researchers and end users in one, with the number of participants more than 3,000.
After careful, I have finished the report of the manufacturer and expert, and after visiting the CNGi demo network of the General Assembly, summarized as follows:
1. Network Equipment Manufacturer (Cisco, Hitachi, Juniper, Huawei, etc.) has made a lot of work in IPv6, and its product features: hardware implementation (high speed), IPv4 / V6 dual protocol stack, supply capacity of each grade product in the whole line.
CNGI demo network - Shownet is based on Cisco, Hitachi, Juniper, and Huawei products. SHOWNET is based on a variety of routing protocols, inter-domain: BGP 4 , domain: OSPF V3, IS-IS V6, RIPNG. The routers between each autonomous domain are connected through 10G Ethernet.
Summary: Network device manufacturers have made a lot of preparations for IPv6, which has end-to-end IPv6 solutions (including: access layers, aggregation layers, backbone, V6 / V4 interoperability). Huawei company's performance makes each representative feel a shock. The software platform of all the company's data communication products - VRP has already supported IPv6. The platform has been developed in Huawei Indian Software Institute (CMM 5), which has invested 240 Chinese-launched engineers, lasted for two years, invested more than 200 million yuan. In addition, Huawei's high-end IPv6 ASIC is coming soon (2004.7), which is the longest (3 years) of Huawei (3 years), which is going to invest the largest (140 million) a chip project.

2. IPv6 network applications are still inadequate, which is also the root cause of IPv6 delay. The IPv6 displayed in ShowNet is not more than more, including: IPv6 webcam, IPv6 visual conference system, etc. These applications are far from trying to pay for the consumer for IPv6.
Summary: The application of IPv6 is still pale, and operators are cautious about deploying IPv6.
Small tidbits: I heard a participant said: "No matter how beautiful CNGi's prospects, now it is still more than China Telecom (Netcom) pays attention to Xiao Songtong, the latter is the only gold and silver! ".
3. There are no safety in the conference, there is no safety product display. Although the ShowNet's network topology claims that there is an IPv6 firewall, the firewall is not involved in the actual display. The firewall comes from the Chinese Academy of Sciences calculation, and the inquiry is known to be a simple firewall based on software implementation.
4. Many end users have also come in this conference, such as: Shenzhen University Network Center, Renmin University Network Center, China. They have recently upgraded the network, which is more concerned about the applicability and scalability of the current investment in the future.
Summary: End users 'attention to IPv6 will stimulate network equipment manufacturers for IPv6 investment, and network equipment manufacturers will affect more users' attention. This loop will promote the benign development of IPv6 industry. Conclusion: Through this participation, we clearly see the current situation of IPv6 development, IPv6 is gradually moving towards the stage. What people have for IPv6 have been manipulated: Is it possible to deploy IPv6? Go to: How to deploy IPv6 to save resources to the maximum resource. Although IPv6 pale application model is not enough to deploy IPv6 under the operation. With the maturity and influence of IPv6 technology, more and more end users will pay attention to IPv6, they care about whether they will invest in smoothing and apply in IPv6 networks. When more and more end users choose to invest in IPv6, the more opportunities for IPv6 will also be bigger!
