Why is there a dual-line technology?

As we all know, China Internet (CHINA NET) service providers are mainly divided into the South. The two state-owned enterprises of China Telecom and China Netcom in the north share the CHINA NET network service. Therefore, the North-South interoperability problem has become the most headache for Chinese Internet users and Internet content service providers (ICP). Commercial website services are getting more and more, and viewers and customers are becoming more and more critical. The network service providers who have undergone the bubble economy in the Internet industry in China have been quite aware of the fact that "only the true quality service for netizens is the only way out for all websites!" Visitors such as netizens and customers provide high-speed network information services, which every network information service provider has always dreamed of.

What is the significance of dual-line technology?

According to recent surveys of Internet users by Internet authoritative agencies at home and abroad, the slow browsing speed of websites is the most intolerable website disaster for netizens. The resistance to this problem is greater than spam and pop-ups. However, the slow browsing speed is usually caused by mutual access between different ISPs, not because the website information content provider's website bandwidth is not enough, simple sentence, double line Technology is to let our netizens and customers bid farewell to the long wait for low cost!

What are the characteristics of dual line technology?

Dual line technology implementation can not increase hardware costs. You don't need to add more maintenance personnel to update, you don't need to spend more energy, just a little bit of different ISP bandwidth access, you can use and use the server's network and hardware resources to improve the traffic. . ---- Her biggest feature is to improve website access speed simply and effectively. Therefore, in the future development of China's Internet, this technology will become the most popular information service solution technology solution for website content information service providers.

Is the dual-line technology difficult to implement?

The implementation of dual-line technology requires our professional engineers and technicians to respond to the user server network configuration and data IDC central room core routing equipment. Setting up, in conjunction with the upcoming LDN technology of ** data, it can be said that selective intelligent resolution of only one domain name can completely point your service visitors to the same ISP. The configuration is all done by our network engineers. Although the dual-line technology is more complicated in configuration, it does not need to know any related technology for the user, and does not require the user to set anything else.

Is the stability of the dual-line technology high?

Dual-line technology needs to be configured by our professional engineers and technicians. The configured server is no different from the two servers you use in two computer rooms, so there is no difference in stability.

What is the specific method for implementing dual-line technology in data centers?

Most data centers use dual-NIC technology in the server to ensure high-speed stability of server dual-line technology applications. The two network cards are respectively bound to the telecommunications and Netcom ip addresses for specific implementation. //This article is quoted from the computer software and hardware application network

Why not use the single-IP dual-line solution?

Because the network communication working principle according to TCP/IP protocol can be known, when the visitor acts as the initiative When connecting to the server (source address), the server accesses the Internet regardless of whether it uses telecom or Netcom network. Even if we configure the core routing device of the equipment room, all active users accessing the user can only connect according to the default route of the ISP! Therefore, this method can not guarantee high-speed and fast access, in order to ensure the stability and speed of the server, we recommend our customers to use dual network card + dual ip access.

Make your previous two servers each placed in the Telecom and Netcom room for users to choose to access. Now only one server is required to place the dual-line room to be truly fully automated to achieve Telecom Netcom interconnection. Reduce costs for your operations and bring greater benefits to your business.

Dual network card + dual IP mode makes the server use two network cards, will it reduce the performance of the server?

The server hardware platform and its operating system are designed for multi-network card multi-route Developed, many Internet cafes currently use a proxy server (dual network card + NAT) to provide access to the client, and have not seen any performance degradation. Most servers are also the default two network cards, so the impact of dual NIC + dual IP technology on the performance of the server can be completely ignored.

What are the shortcomings of dual-line technology?

This technology adds a hardware cost to the server (the professional server defaults to two network cards, if it is a single line, it will definitely Idle a network card, so I said that there is basically no increase in the hardware cost of the server.

What can dual-line technology bring to us?

Dual-line technology is a major technological innovation in the development of the Internet. She has built a fast link between website content providers and Internet users. The bridge of communication has increased the access advantages, reduced costs and greatly improved the competitiveness of portal websites, large and medium-sized enterprise websites, information portal websites, mall websites, personal websites and game industries.

Which industries are suitable for dual-line technology?

I hope that the services and information provided by my website can be easily accessed by the industry, such as portal websites. Large and medium-sized enterprise websites, information portals, mall-like websites, personal websites, game industries, etc., data centers usually provide dual-line system solutions for different industries for different industry users. //This article comes from www.45it.comComputer Software and Hardware Application Network

Is the dual line technology hosting lease high?

Dual line technology is compared to single line technology, **Data Center The hardware and network equipment and operating costs will be more than doubled, but for the majority of users, you can save a space and power consumption, and maintenance is more convenient. So no matter which aspect you compare, using dual-line technology will be much lower than if you host two servers at the same time to different IDC rooms.

What preparations should be made before choosing a dual-line technology solution?

A two-line server must have at least two network cards, and once the dual-line solution is implemented, it will be in the existing traffic. Based on the above, it may double or higher to bring more traffic to your website, which means that the server will increase the bandwidth and data throughput by at least doubled! If the software and hardware performance of the server does not meet the access response requirements, It may cause frequent downtime on your server. Therefore, you should expect the load that the server can bear according to the performance of the server hardware and software and the increase in website access traffic.

Do the corresponding upgrade work in advance (such as increasing the total number of physical memory, cpu or computing power, improving disk performance capacity, upgrading disk raid; upgrading aspects of software such as upgrading operating system, upgrading website main program or service The end program, the main program of the website or the main program of the server can preferably use technical support, so that once there is a problem, technical support is very important), so as to avoid unnecessary loss under the request of large data.

There is nothing to ignore. As the number of visits increases, more industry opponents or some good people may be "very concerned" about your website. Therefore, it is also necessary to strengthen the security work of your server and website!----One sentence in total: Precautions, the heart of the victim can not be, the heart of the person can be indispensable, can be invincible, steady and fast development of.

Two servers are hosted in two computer rooms, and one server is placed in the same data center IDC room. What are the advantages and disadvantages of using dual-line technology?

Hardware investment comparison: Dual server The hardware investment is big. Two servers believe that everyone knows that it will be more expensive than a server. The dual-server hosting cost is high. Everyone knows that the two-machine dual-line will cost more than one machine and two lines!

Update maintenance comparison: dual server, maintenance update trouble, update this machine, but also update that station, just updated the Netcom side, but also to update the telecommunications side, the two sides of the data synchronization is difficult to achieve . . . . With dual-line technology, you can always make the server's data update on both sides, saving you manpower and valuable time to do more things that are good for your development.
