As we all know, China and the United States are just across the globe, across the Pacific Ocean. For the "friendship" of the peoples of the two countries and the interconnection of networks, data transmission between China and the United States over the Internet, telephones, etc. must be carried out through the submarine optical cable across the Pacific Ocean.
There are two direct current submarine cable between China and the US, is a direct Sino-US undersea fiber optic cable (China-US CableNetwork) , network capacity reaching 80Gbps . The landing sites in mainland China are Shanghai Chongming Island and Shantou , and the landing sites in the United States are San Luis Obispo (located between San Jose and Los Angeles) in California .
- Shantou
- Fangshan Township, Pingtung County, Taiwan Province
- Chongming County, Shanghai
- Okinawa Prefecture, Japan
- Busan, South Korea
- Chiba Prefecture, Japan
- Tamuning, Guam
- Bandon, Coos County, Oregon, United States
- San Luis Obispo, United States
The other, the famous Trans Pacific Cable , has a design capacity of 5.12Tbps . The mainland landing points are Shanghai (China Telecom) and Qingdao (China Unicom) . The US landing point is Nedonna Beach in Oregon . Both optical cables have been commercialized, but from the results of my many traceroutes at present, it seems that TPE has not been opened to ordinary broadband users.
The bandwidth growth rate between China and the United States is quite alarming. According to the statistics of CNNIC, the bandwidth between China Telecom and the United States was 203980 MB at the end of 2008, while China Netcom was 110456 MB. Currently, China Telecom ’s nodes on the west coast of North America are Washington State. In Seattle, San Jose, California, Los Angeles and Parato.
Then, when we choose the server room to place or purchase VPS, please choose the nearest computer room offshore.
General telecommunications / Netcom users go to the US site network to transmit data through the local ISP network, then the metropolitan area network, then the provincial and municipal network nodes, then the backbone network, and finally export from Shanghai and other cities, spanning more than 10,000 kilometers After the vast Pacific Ocean , it landed in California / Oregon . Network latency (latency) is above 200ms .
Many people mistakenly believe that G_F_W's network filtering will affect the network speed, but in fact this effect is negligible. The network delay above 200ms is mainly due to the long transmission distance. The Japanese / Australian netizens' network delay to the United States and the mainland The users are similar, and European users generally cross the Atlantic Ocean for more than 100ms.
If you are a mobile user, the bandwidth resources should be pitiful for the two giants. Mobile users generally go south to Hong Kong to connect NTT nodes, then bypass Japan to the United States, and the network delay reaches an astonishing seven or eight hundred milliseconds. . So if you want to play games or videos from American service, please do not use broadband provided by operators other than Telecom or Unicom. For example, some local broadband operators such as Mobile, Tietong, Great Wall Broadband, Gehua Cable, Tianwei Shixun, etc., although cheaper, because of his weak broadband. 100M is also a cock, dropping packets, delaying, etc.
In this way, the location of the best computer room for mainland users should be in West Coast California. There are three most concentrated computer rooms in California, SanJose (San Jose), Fremont and Los Angeles. Among them, SanJose and Fremont are located in the Bay Area, which is the entrance of Silicon Valley. Therefore, according to my years of experience, the best ping value from China to the United States is generally 140ms (when the character and location are very good), normally about 200ms, if you insist on comparing with the domestic 30ms, it is indeed defeated. Then you can choose to immigrate to the United States! But with a measured delay of 200ms, there is no pressure to play games and watch videos!
