Recently, the cn2 line has become more and more popular. Many customers only look for the cn2 line when renting a Hong Kong server. So what advantages does the Hong Kong cn2 server have? How to judge whether the Hong Kong server is a cn2 line?

CN2 serves the key business of China Telecom itself and the SLA business of QOS guarantee. It can provide high-performance network metrics. The average single-item delay, the maximum single-item delay, and the single-item packet loss rate are all at the top level. The CN2 line of the Hong Kong server far exceeds the ordinary network in terms of access speed and network stability. It is the fastest and most stable network line from the mainland to Hong Kong.

How to judge whether the server is a cn2 server?

We can judge whether the server line is the cn2 line through route tracing. The Windows system uses the tracert command, and the Linux system uses the mtr test. Get the routing node from the local to the target ip, if there are 59, 43, *, *, it is the cn2 line, and vice versa. Second, the lines are bidirectional. In addition to route tracing from the local to the computer room, route tracing from the computer room to the local is also required. The method is the same, to judge whether the CN2 line is bidirectional.

The CN2 line is not without its drawbacks. While ensuring high quality and high stability, the price is much more expensive than other ordinary lines. Users can decide whether to use CN2 line according to their own budget.

Advantages of Hong Kong cn2 line server:

First, at the IP level, Hong Kong's direct connection to the CN2 server line achieves fast route convergence of less than 500ms on average, smooth restart of IGP/BGP protocols, network-wide multicast, and has the potential for a smooth upgrade to IPv6.

Second, the CN2 backbone network directly connected to the CN2 server line in Hong Kong adopts a three-layer network structure: the core layer, the connection layer and the edge layer, and the corresponding nodes are the core node, the connection node and the edge node. At the same time, the construction of CN2 backbone nodes, business nodes and overseas POP nodes covering 31 provinces, autonomous regions, and municipalities directly under the Central Government has been realized.

Third, the biggest advantage of Hong Kong's direct connection to CN2 server over other domestic lines is that it solves the problem of data exchange between different ISPs, and the problem of network access between China Telecom, China Unicom, and China Mobile, so it is faster and more stable!

Fourth, the line directly connected to the CN2 server in Hong Kong carries SLA services with QoS guarantees on CN2, and in order to meet the QoS requirements of the carried services, CN2 provides high-performance network indicators. For example, significant progress has been made in one-way delay and one-way packet loss rate. Therefore, the use of CN2 server can increase the flexibility and scalability of enterprise business.
