1. Related concepts

Now we introduce CN2 GIA and some related concepts.

ChinaNet: The world's largest Chinese resource Internet network, also called the 163 backbone network, is the first line established by China Telecom to access the international Internet. Because there are many people using it and the level of optimization is low, the outbound routes are relatively congested, the speed is slow, and the packet loss rate is high.

CN2: English Chinatelecom Next Carrier Network, Chinese is China Telecom's next generation bearer network, abbreviated as CNCN or CN2. CN2 is a project established to provide China Telecom's backbone bearer network with higher quality requirements. It operates global Internet transfer services and can achieve high-speed, large-capacity, safe and stable transfer services between Europe, North America and Asia.

CN2 GT: GT stands for Global Transit, providing transfer services for global customers to access global Internet resources. CN2 GT international export has its own separate line, but the link in mainland China still uses the 163 backbone network. The line is generally in good condition and moderately loaded, so good speeds and latency are guaranteed. The level in CN2 is low and better than the 163 backbone network.

CN2 GIA: GIA is Global Internet Access, which is the highest level and has an excellent experience in speed and latency. Note that GIA specifically refers to dedicated line services with China, providing corporate customers with high-quality China-directed Internet dedicated line access services. It is connected to the CN2 (AS4809) network, and the entire export is routed by CN2 (AS4809). The international line is connected to the network in mainland China at high speed and stably. The main advantage of GIA is that it has a separate line back to the country, with high priority and high quality, but the access price is relatively expensive.

One-way/two-way (one-way/two-way) CN2: The route is two-way, going and returning. One-way CN2 means that only one side goes through CN2, and the other side goes through other networks. The two-way route goes back and forth. CN2. Peak congestion mainly occurs at the international entrance, so the optimized route takes at least CN2 for the return trip, including CN2 GT and CN2 GIA.

Three Networks CN2 GIA: Generally speaking, telecom users will use CN2 GIA lines, but some businesses optimize routing and let China Mobile and China Unicom users also use CN2 GIA, which is faster than direct connection.

BGP: Directly connect to multiple operators without going through a third operator.

IPLC: The abbreviation of "International Private Leased Circuit" refers to a user-dedicated cross-border communication line for comprehensive information services such as data and voice. It has the advantages of low latency, fast speed, and does not pass through the wall. The disadvantage is that the traffic is expensive.

In general, the ranking in terms of speed is: IPLC > CN2 GIA > CN2 GT > No optimization line.
