Hong Kong's CN2 bandwidth road capacity is generally not too large, generally between 3m and 10m, because the price of CN2 bandwidth roads is very expensive. The bandwidth is very large, and many users will not use it. In order to attract customers, many merchants will promote CN2 bandwidth to fool customers, so users must distinguish them clearly when choosing. Today, the most used overseas computer rooms on the CN2 bandwidth are Hong Kong machine rooms, American computer rooms and Southeast Asian countries.

　　The difference between the use of the Hong Kong CN2 bandwidth and the non -CN2 bandwidth will not be very large, because Hong Kong is close to the mainland, and its line is interacting with the mainland, but if you choose the US CN2 bandwidth road, it will be different. Hong Kong's CN2 bandwidth road is mainly for users who want to quickly open the website, but the general bandwidth is not very large, so it cannot accept too much traffic. The US CN2 bandwidth can accept a large amount of traffic, but the speed is lower than Hong Kong, and the two are complementary.

　　Through the above description, we know that the Hong Kong CN2 bandwidth is relatively small compared to ordinary bandwidth. Users who intend to choose the CN2 bandwidth will have a clearer understanding, so as to better choose the CN2 bandwidth that suits them. At present, the most useful overseas computer rooms connected to the CN2 bandwidth are Hong Kong machine rooms and American computer rooms. Because the bandwidth of the Hong Kong CN2 bandwidth is relatively expensive, the bandwidth of the Hong Kong server CN2 provided by many Hong Kong IDCs is also very small, generally only about 5m.

　　Based on the straight line distance from Beijing to Los Angeles, 1s (seconds) = 1000ms (milliseconds), even if the speed of light is about 70ms. If a ping request is sent to the US server, and no more interference, the data needs to be issued and accepted at least 140 milliseconds. The ping value of the server is about 180ms.

　　If the PING value measured by the service provider is between 170ms-180ms, it is considered fast. If the data of the U.S. room has passed through multiple routers before entering the submarine optical cable, it is not surprising that the transmission speed is 200ms.

　　1. For the US CN2, the most significant advantage of the Hong Kong CN2 server is that it has fast access and good stability. Because the China Telecom line line connected by CN2 bandwidth is much faster than ordinary lines, it has low delay, low packet loss rate, and high safety. Therefore, if the webmaster who needs to be highly required, the use of the CN2 Hong Kong server is comparable to the domestic network speed. Generally, the PING value is about 30ms.

　　2. The CN2 bandwidth Hong Kong server can be exempted from filing, and the control is relatively loose. For webmasters, you can build most of the legal websites. If you rent a CN2 bandwidth Hong Kong server, you can build your own website at any time.

　　3. The biggest advantage of the Hong Kong direct CN2 server for other domestic lines is to solve the problem of data exchange between different ISPs. Telecom, Unicom, Mobile and other online visits issues, so it is faster and stable.

　　4. Hong Kong Direct CN2 server lines are carried out with the SLA business with QOS guarantee, and in order to meet the requirements of QoS, CN2 provides high -performance network indicators. For example, there have been significant improvements in one -way delay and one -way packet loss rate. Therefore, using the CN2 server can increase the flexibility and expansion of the business business.

　　The Hong Kong CN2 bandwidth is currently positioned in large customer business and high -quality Internet business. The price is relatively high, far exceeding the normal network bandwidth. However, it is not that the bandwidth of CN2 is outrageous, but it is more expensive than ordinary lines, but it is also within the range of most users. The Hong Kong CN2 bandwidth is suitable for the smooth development of international interoperability, foreign trade e -commerce, direct sales, online games, international mail receipt and other businesses for the customer base for mainland China, Southeast Asia and even the Asia -Pacific region.
