At present, Google BBR is widely used in TCP unilateral congestion algorithm. Even some small partners have developed BBR violent version, BBR violence magic version, BBR plus version, etc. at present, many people use sharp speed, but sharp speed has broken down. This is not recommended,Among the BBR versions, BBR plus is the best.Tencent's kernel team has recently announced that it uses TCP unilateral congestion algorithm TcpA, which can be used by webmasters, individuals and enterprises for free.
For station users, TcpA is more suitable, but BBR plus is more suitable for large bandwidth applications such as watching videos.
Tencent internal use of TcpA, Tencent TEG operating system group research and development, based on rhel7.4 source code, customized TcpA.
Tencent TEG operating system group, established in 2010, has a professional kernel team to maintain and develop Tencent's internal Linux operating system tlinux, so as to ensure the efficient and stable operation of millions of servers and provide strong support for Tencent business.
Advantages:After TcpA is enabled, small files can be increased by more than 40% compared with BBR, and large files can be increased by 5% ~ 10% compared with BBR.The advantage of TcpA lies in the performance improvement of small files.By default, the program only speeds up ports 80, 443 and 8080, which is more suitable for site building scenarios and can be added by itself.
