Telecom expansion: CN2 GT speed increased, packet loss reduced, with speed comparison before and after expansion

In "163 Backbone Network / CN2 GT / CN2 GIA Route Concept Introduction and VPS Service Provider Recommendation", this site introduces the concepts of Telecom 163 and Telecom CN2. Recently, Telecom's international bandwidth seems to have expanded a lot, CN2 GT The speed has been significantly improved, and packet loss is much less than before. This article compares the speed and packet loss before and after the telecom expansion.

1. Speed ​​comparison before and after telecom expansion

Although CN2 GT is also optimized for Telecom CN2, the speed was very slow before. This was shared in the Bricklayer DC3 data center review "Bricklayer DC3 CN2 GT Evaluation: Speed, Delay, Packet Loss Rate and Routing Test" shared in 2020 It can be seen that the telecommunications speed is very unstable:

After the expansion, the telecommunications speed of the same data center has been significantly improved. This is also shared in the "2021 Bricklayer DC3 CN2 GT Telecom, China Mobile, and China Unicom Three Network Speed ​​Test":

2. Comparison of packet loss before and after telecom expansion

In addition to speed, packet loss rate is also very important. If the packet loss is serious, even if the speed test result is good, it will feel very slow in actual use. When building the website, the web page will not be opened at all, and it will be very laggy. Packet loss before CN2 GT The rate is also very high, also taken from the 2020 Bricklayer DC3 data center review "Bricklayer DC3 CN2 GT Evaluation: Speed, Latency, Packet Loss Rate and Routing Test"

Now in the same DC3 data center, the packet loss situation has also been greatly improved:

3. Recommended telecommunications optimization solutions

In short:

• Before expansion: only CN2 GIA can be used in Telecom CN2, and CN2 GT is not working
• After expansion: the speed of CN2 GIA is naturally better, and the speed and packet loss of CN2 GT have also been greatly improved
