One yuan CN domain-wide experience activities and national domain name Take-off plan

With the "one Yuan CN domain name national experience activities and national domain name Take-off plan" Implementation and the rapid spread in the country, CN domain name register quickly climbed.

CNNIC director Mao Wei said that the rapid growth of the CN domain name registration, on the one hand, reflects the government for the country's top level domain name as a national strategic resources of the high priority, and, on the other hand, due to the frequency of broken network crisis, domain name users of the national top-level domain security can understand more More and more enterprises from the Internet also began to switch to CN domain name. CNNIC announced that the Domain Name Service quality report shows that despite the rapid growth of the CN domain name, but the CN domain resolution response rate has been maintained at 100%.

It is not difficult to see that the safety factor is the national domain name CN take-off A big impetus, and cnnic for the maintenance of Chinese domain Name system to run the triple insurance, has become the escort of national domain name CN take-off The most solid background protection.

First insurance: Ensure the "central nervous" smooth

At the end of 2006, the "Broken network" crisis still makes the netizens remember, due to several strong earthquakes in southern Taiwan Sea, resulting in at least 6 international submarine communication Cable rupture, leading to domestic access to foreign domain name resolution interrupted.

Why the small domain name can set off the Internet uproar? How did the rupture of several cables lead to such serious consequences? The key problem here is that domain name resolution is interrupted.

CNNIC Assistant director Liuzhijiang for reporters to do a figurative analogy, if the internet compared to a person, then a variety of web sites and network applications like people's muscles and skin, data communication lines and hardware equipment is human skeleton, and the domain Name system is like Human central nervous. It is not difficult to understand that individual Web sites or data communication line failures can only produce local impact, and the domain Name system failure caused by domain name resolution interruption will cause the entire Internet paralysis. Therefore, the submarine cable interruption is due to internet COM domain name resolution pathway in the "spine fracture" indirectly affected the central nervous, so that the internet has caused a large area of paralysis.

And cnnic is the CN domain Name System This Internet central nervous management defender. "China can not be a day without the Internet, the Internet can not be a day without cnnic," the reporter visited the cnnic room after the issue of such feelings. In the cnnic of the monitoring room, the electronic screen in seconds to beat the number is very eye-catching, distributed in the country's 5 domain name resolution of the top node almost covered the south and north of all telecom operators, 24 hours of uninterrupted domain name analysis to protect the Chinese Internet application of the stability of implementation, Servers that are located on each node always respond to requests from netizens to log on to the site. Maintenance of the "central nervous" daily smooth for China's domain Name System operation on the first "insurance."

Second insurance: Five nodes escort CN domain Name

In order to be able to calmly deal with the potential crisis of China's Internet, cnnic for CN domain name analysis of the country-wide node layout, which is cnnic on China's Internet address resource platform on the second "insurance." CNNIC Technical director Xiaodong told reporters that in most cases, the CN domain name mainly through the domestic domain name server resolution, users visit the CN domain name of the site more stable and fast. At the same time, responsible for the CN domain name resolution CNNIC launched the multi-node CN top Node deployment plan, thus greatly improved the stability of the CN domain name. The top five top-level nodes were deployed last June and are fully enabled.

Compared with the original node, the new top-node advantages are more prominent: first, the distribution of more reasonable, all over China's major ISPs, so as to ensure the fairness of different ISP users access to the domain name, so as to effectively balance the CN domain resolution flow; Second, the performance is more superior. The new top-level node emphasizes the minimization of the number of hops from the national backbone nodes, and the optimization of the domain Name Service processing capability, which ensures the network access performance of the nodes, which is like driving to a certain destination, traveling on the expressway, which is very convenient and quick, and the structure is more secure. The new top-level node in the design process, fully considered in recent years the development of Internet security issues, from the framework, performance, strategy to ensure that the new node has a high security.

The deployment of the new five top-level nodes, like eggs in different baskets, spread the risk of a single node architecture, even if a node system failure, does not affect the CN domain name resolution.

Third insurance: Crisis warning and anticipatory

In the CNNIC data protection system, in addition to taking all kinds of preventive measures, but also prepared a fairly rigorous contingency plan, in the worst case, you can emergency recovery of domain Name System, provide normal domain name resolution and management services to ensure the normal operation of CNNIC data.

"We have data centers in Beijing, data backup storage, and multiple branch nodes in other cities and overseas," Cnnic said, CNNIC's data capacity has been growing at a geometric level, facing significant data security responsibilities, Although the data core has been safely stored in the CNNIC center room, as well as in other backup rooms, and cnnic for these rooms have already used a redundant network structure, important data offsite distribution, the same city data backup and a series of security measures.

At the same time, a more secure and complete disaster recovery backup program has been put on the CNNIC key agenda. CNNIC engineer said: "From the disaster preparedness intention to the final conclusion, spent a full two years." "Disaster preparedness is the last line of defense for information security and must be handled with care," he said. Domestic cities have entered our horizons, but after many comparisons, Sichuan Telecom Disaster Preparedness Center in the network quality, physical conditions, management level are well satisfied with the disaster preparedness needs, the final disaster preparedness in Chengdu.

For China's Internet address resource platform, the three-way cnnic set up a three-dimensional security system, "central nervous" maintenance to ensure the day-to-day domain name analysis of the stability of the operation, the opening of five nodes to improve the security and efficiency of the analysis, and the disaster-preparedness system guarantees the rapidity of reconstructing the central nervous system after the analysis of paralysis from the data source. For network application based on network Address resource platform, this triple insurance provides a safe, powerful and reliable support to improve the performance of Internet infrastructure in China, so as to effectively guarantee the healthy and orderly development of Internet in our country.
