TCP single side congestion algorithm, Google BBR is currently in great use, and even small partners have developed BBR violent version, BBR violence demon version, BBR plus version and so on. At present, many people use sharp speed, but sharp speed has the situation of disconnection, this is not recommended.BBR BBR plus works best in all versions.Tencent core team recently announced the internal use of TCP unilateral congestion algorithm -TCPA, stationmaster, individual, enterprise can be free of charge.
TCPA is more suitable for station users, but if you want to use large bandwidth applications such as watching videos, or BBR PLUS is more suitable.
The TCPA used by Tencent is developed by Tencent TEG operating system group, based on RHEL7.4 source code and customized TCPA.
Tencent TEG operating system group, established in 2010, is a professional core team. It maintains the R & D of Tencent's internal Linux operating system tlinux, guarantees millions of server efficient and stable operation, and provides strong support for Tencent business.
Advantages:After TCPA is enabled, small files can be increased by more than 40% over BBR, and large files can increase 5%~10% over BBR.The advantage of TCPA lies in the performance improvement of small files.The program only accelerates 80, 443 and 8080 ports by default, which is more suitable for building station scenarios, and can add ports by itself.
