What is the ping value of the US CN2 server? The ping value of the US overseas CN2 server is about 170ms: The Ping value of the US server is normal at about 170ms. If the data in the computer room needs to be transmitted through multiple routers, its Ping value is also normal if it is above 200ms.
　　The specific content is as follows: Nowadays, the network is transmitted in the form of optical fiber during the transmission process, and the bandwidth and speed of transmission have been qualitatively improved. At present, the distance between China and the United States is nearly half of the earth. Calculated by the distance from Beijing to Washington, it is about 11,200 kilometers. Even if the optical fiber transmission speed reaches 300,000 per second, which is equivalent to 7.5 laps around the earth per second, according to the time 1 second = 1000 milliseconds, it takes about 70 milliseconds to reach the United States through optical fiber.
　　1. What is the US CN2 server? What are the advantages?
　　1. The basic concept of CN2 server
　　The CN2 line is a high-quality commercial circuit quality service launched by China Telecom. The server connected to the CN2 line in the computer room is called a CN2 server. Its characteristics are high line quality and strong stability. Moreover, it has good credibility in China. Many domestic users will choose to use the US cn2 server when using foreign VPS.
　　The US server renting CN2 line has the following advantages:
　　Low latency: The minimum ping value from the US server to China on the CN2 line is only 140ms, and the website access speed is very fast.
　　Large bandwidth and large traffic: Compared with other foreign servers, US servers have larger bandwidth and traffic resources.
　　Bandwidth back to China: The CN2 line is convenient for domestic users to use US servers to access foreign websites.
　　Stability: The US CN2 cloud server uses the telecom CN2 dedicated line to connect to the mainland in both directions, and its speed and stability far exceed ordinary networks.
　　Ping value test of US cn2 server
　　For large websites and applications, stable and high-speed servers are crucial. US server renting CN2 line can meet the construction needs of various large websites such as enterprises, e-commerce, foreign trade, and videos. Not only that, the US computer room management is professional, and the data center has advanced equipment and technical support to ensure the stability and security of server operation.
　　2. Definition of ping value
　　Ping value is a performance indicator in computer network tools. It is used to test the delay time of data transmission in network communication. Simply put, it is the time that a computer is communicating with another computer.
　　3. How to test the ping value
　　When testing the ping value, users can use the command line or test software. The command line program is a tool based on the TCP/IP protocol. Users can directly execute the PING command in the command line window. The test software is relatively simple and easy to use. Commonly used ones include QQ browser and Chrome browser.
　　4. The ping value of the US cn2 server
　　Due to the influence of geographical location and network bandwidth, the ping value of the US cn2 server is not unique and there will definitely be differences. However, when performing this measurement operation, we can get the average value, which is enough for domestic users. The average ping value of the US cn2 server is about 120ms-180ms, and there will be some jitter during peak periods (such as at night).
　　2. How to reduce the ping value of the US server?
　　Webmasters all know that when users use US servers, when the server sends a Ping request, the transmitted data needs to be transmitted twice, and when it is not affected by any interference factors, it takes at least 140ms to transmit data. In the data request, it also needs to pass through the processing time of the router and the server, so the Ping value of the US server is estimated to be nearly 170ms, so the choice is to use the US server Ping value within 200ms, which is relatively fast. If the data in the US server room needs to be transmitted through multiple routers before entering the submarine optical cable, even if the Ping value is above 200ms, it is normal.
　　To reduce the ping value of the US server, the following points need to be done:
　　1. Choose a good US cn2 server; 2. Choose a stable bandwidth; 3. Use a split protocol during network transmission.
　　All of the above are solutions that can successfully reduce the ping value of the US server. The US server renting CN2 line is the first choice for domestic users. It not only provides a stable and low-latency network connection, but also has the advantages of large bandwidth, large traffic and return bandwidth. If you want to use the US cn2 server better, you also need to work hard in the above aspects to avoid the problem of too high ping value.
　　Currently, the closest US server to China should be the data center in California, which is located on the west coast of the United States, so the server in this data center is also very fast in China. The average ping value of the US cn2 server is about 120ms-180ms. When we use the cn2 server, we need to understand the definition of ping value, how to test ping value, and how to reduce ping value, so as to better utilize the advantages of the cn2 server.
