Solving the North-South Network Problem Qiandu North-South Interoperability

  
                  "The farthest distance on the Internet is not from China to the United States, but from telecommunications to Netcom." Although this is a joke, it truly reflects the current reality of the domestic Internet. The average home user, whether it is sending files or video chat, will greatly slow down in the process of "north" or "southern". As for online games, it is even more important to choose a local server, otherwise too high a ping value will make you extremely depressed. The author has also worked in some companies in Shanghai. With 10M bandwidth, when sending files to colleagues in Beijing, the transmission speed is almost slower than the turtle speed, and it can't be solved at all. For this reason, I still have a lot of bosses. Solving the problem of the speed of the North and the South has become a big hope for Chinese netizens. It is based on the belief that the North and the South are interoperable, and Qiandu came into being. Principle

thousand crossing North-South exchange is actually very simple, equivalent to the concept of VPN. It purchased the server and the dedicated line of Telecom and China Netcom. After using the company, the user first sends data to the server of Qiandu when accessing the network, and then the server sends a data request to the website. It can also be understood as using a proxy server. Some readers may ask, isn't this a node more, isn't the speed slower? According to the theory, the two sides of China's north and south are the networks of telecommunications and Netcom. The data transfer rate between them is very slow, which is equivalent to connecting the other party's network through a small pipe. The Qiandu server is like a big pipe, which is connected to the network of Telecom and Netcom. Whether you are a telecom or Netcom user, when you connect another network through the server of Qiandu, you use the large pipeline of Qiandu as the transit. Go up.

Frequently Asked Questions about Qiandu:

As a newly launched software, Qiandu still has some problems like this. The author went to the Qiandu Forum to check some posts and collected some common questions. And the solution, I hope to help everyone.

1. I do not thousands of ferry landing server, how to solve the Arab-Israeli?
First download the latest 2.3 version on the Qiandu website http://www.1000du.net. When logging in, select the 4 5 6 server in the server list and try it out.

2. Why do I visit some websites after I use Qiandu, but it is slower than before.
Remove the "automatic routing mode" before logging in and log in again.

3. Why do I play online games after using Qiandu, the ping value is still very high.
Some online games (such as CS) and programs use the UDP (User Datagram) protocol for communication. Qiandu cannot send and receive data based on UDP protocol, so it cannot improve the connection speed of these games and programs. Try to go down the "automatic routing mode" and log in again.

4. I am a user, why is it that the landing of Qiandu always fails.
First check if the operating system installs a firewall. If so, please turn off the firewall or add the corresponding rules in the firewall software. If there is a router in the network, you need to contact the network administrator to set the PPTP option to allow.

5. I am a long-width/iron-pass user. Is it effective with Qiandu?
Qiandu is currently only connected to the network of Telecom and Netcom, and has no effect on other broadband access.
