Improving FreeBSD’s transport layer

Posted: October 9th, 2015 | Author: | Filed under: FreeBSD, networking, tcp | Tags: , , | Comments Off on Improving FreeBSD’s transport layer

FreeBSD network stack is quite stable but lacks some of the improvements/features available in other OSes.

A bunch of us have started an effort to try and identify current problems to improve transport layer (TCP, UDP, SCTP and others) for FreeBSD:

Transport Protocols wiki

Traditionally, freebsd-net has been the mailing list where networking problems get discussed but some have complained it to be too spammy and too focused on NIC drivers related issues. So a new mailing list has been created to specifically talk about transport level protocols: transport@

We’ve also started creating a list of TCP related RFCs and their support for FreeBSD to have a single point of reference.

Plan is to have a coordinated effort to improve TCP, UDP, etc.. so if you are interested in any of those protocols, please join the mailing list and help FreeBSD. :-)
