Description

These are provided via kernel modules cc_cubic and cc_htcp

I am aware pfsense when its not the endpoint these are useless, but when a VPN is configured on the router, then the router becomes an endpoint so as such these have merit in configurations where a VPN is configured.

Add congestion control modules. Implements #7092

History

#1 Updated by Jim Pingle almost 2 years ago

  • Category set to Operating System

There are more available now:

/boot/kernel/cc_cdg.ko
/boot/kernel/cc_chd.ko
/boot/kernel/cc_cubic.ko
/boot/kernel/cc_dctcp.ko
/boot/kernel/cc_hd.ko
/boot/kernel/cc_htcp.ko
/boot/kernel/cc_vegas.ko

Current default is newreno, which is built into the kernel.

Set via `net.inet.tcp.cc.algorithm`

#2 Updated by Viktor Gurov 9 months ago

there is no any '/boot/kernel/cc_*' or 'sysctl net.inet.tcp.cc.available' (except newreno) on 2.4.5-p1 and 2.5.0.a.20200812.1850

#3 Updated by Yuran Yastreb about 1 month ago

Before version 2.5.0, I could use these modules, which I make from source code. But since version 2.5.0, this no longer works, and when you try to load the module, the following entries are visible in dmesg:

link_elf_obj: symbol tcp_do_rfc3465 undefined
linker_load_file: /boot/modules/cc_htcp.ko - unsupported file type
