If your Hong Kong server does not choose the CN2 dedicated line directly connected to China, but takes the international line, the network speed is not as good as the servers in South Korea and Japan. If the customer group is concentrated in mainland China, when renting a Hong Kong server, you must choose a line directly connected to the mainland to ensure the speed and stability of the server. The same is true for renting a Hong Kong cluster server. The two-way CN2 bandwidth is more professional and effective for the cluster, and it is also more perfect in terms of security and stability. So, what are the specific advantages of choosing two-way CN2 bandwidth for Hong Kong multi-IP cluster servers?
　　1. What are the advantages of choosing two-way CN2 bandwidth for Hong Kong multi-IP servers?
　　In addition to ordinary lines, CN2 lines are also divided into two types. When purchasing, you must also pay attention to whether CN2 is two-way or one-way. As the name suggests, the routing nodes of the outbound journey and the routing nodes of the return journey all use the CN2 bearer network. The one-way CN2 is generally the outbound CN2, and the return ordinary telecommunications line is slightly inferior to the two-way CN2 in speed.  
　　1. Ordinary 163: This is the telecom line most often encountered by telecom users. It has the lowest level. The provincial/overseas/international backbone nodes all start with 202.97. There is no CN2 node starting with 59.43. It is congested on the overseas route and has a high packet loss rate. Since it was built earlier, in addition to consumer users, it is also used by some large government and business users, and is greatly affected by domestic line fluctuations, so network congestion often occurs. For users who rent Hong Kong servers, this line is the cheapest, but the line quality is poor and the stability is not high.
　　2. CN2 GT: A product belonging to Global Transit in CN2 (also known as GIS-Global Internet Service). It has a low level in CN2. The provincial/overseas nodes start with 202.97, and there are 2 to 4 CN2 nodes starting with 59.43 on the international backbone nodes. The degree of congestion on the overseas route is average, slightly stronger than that of the 163 backbone network, and more cost-effective than CN2 GIA.
　　Since CN2 lines are more expensive, the compromise solution of CN2 GT, a direct line that uses CN2 lines, is adopted. It is one-way and international lines use CN2 lines, which can balance price and speed. Although the return line may be congested sometimes, many computer rooms will choose CN2 GT lines as their main products due to its high cost performance and sufficient bandwidth resources, because Telecom CN2 GT is not its own network exit, but a shared Telecom 163 backbone network exit.
　　3. CN2 GIA: CN2 is the real two-way CN2 direct line, which belongs to Global Internet Access products and has the highest level. The provincial/overseas/international backbone nodes all start with 59.43, and there are no nodes starting with 202.97 throughout the whole process. It performs best on the overseas line, rarely congested, and theoretically has the fastest and most stable speed. Of course, the price is relatively higher than CN2 GT.
　　It can maximize the access speed of the mainland to the Hong Kong server and has the highest network quality. In terms of price, the CN2 GT line is relatively expensive. If the budget allows, the CN2-GIA line is undoubtedly the best network choice.
　　2. Is the CN2 bandwidth Hong Kong cluster server necessarily faster than the VPS of the ordinary 163 hosting network?
　　CN2 determines that the network quality will be better than the ordinary 163 hosting network, but it is not necessarily. In addition to the hosting network, the geographical location of the computer room is also very important. For example, the Hong Kong computer room of JTTI data, students who have used it know that although it does not use the CN2 network, the speed is really...fast because of the close geographical location!!!
　　Finally, after understanding the concept of CN2 and the difference between ordinary hosting lines, I have to give you some dry goods here. Hong Kong multi-ip cluster server rental recommends JTTI Hong Kong multi-ip cluster server. The cn2 return bandwidth has super fast access speed in China, up to 258 independent IPs, which meets the needs of cluster users. The rental cost-effectiveness is high, and it is the first choice for domestic cluster hosting.
　　JTTI Hong Kong multi-ip cluster server CN2 two-way bandwidth cluster server main advantages
　　1) High hardware configuration: With high-performance and high-quality hardware foundation, it can provide a better user experience for a large number of large-scale cluster websites.
　　2) Exclusive direct network: With Hong Kong's top data center, CN2+BGP multi-line domestic access speed is fast, and the ping value is below 20ms, which can ensure fast access to each cluster website.
　　3) Exclusive local IPv4: You should know that there are relatively few IPV4 resources now. JTTI Hong Kong multi-ip server has rich IP resources, all of which are new native IPs with good quality and large quantity. The cluster pages are included in seconds.
　　4) High security: Relying on the top ISP data link, JTTI officials will also conduct security monitoring, which can effectively defend against any common network attacks such as CC and DDOS to ensure the security of the cluster website.
　　5) Cross-C segment can be mixed: Ensure the normal and stable operation of each user's website, and can guarantee 99.99% normal operation time.
　　6) Timely after-sales: Provide 24-hour Chinese technical support, have perfect technical personnel, and perfect after-sales experience. Users can get solutions as soon as they encounter server problems.
　　JTTICN2 bidirectional multi-IP Hong Kong cluster server is the best, divided into 1 segment of 258IP, 2 segments of 250IP, 4 segments of 244IP. Because the IP is dispersed, it can be replaced in time, and the advantage of multiple C segments is that even if the IP is K-ed, it will not involve too many stations, which is conducive to long-term stable optimization!
