NetBSD TCP Congestion Control Configuration Possible?

["Mukosi Mukwevho" <mukosi%gmail.com@localhost>]

Hi Manuel;

 

Complements for 2009!

 

Just a quick question; I am now in the experimentation part of my MSc studies. As part of the research, I need to be able to simulate the ealier version of TCP (as per RFC 793), that means running TCP stack without congestion control algorithms. How can I run TCP stack on NetBSD without the support of TCP Congestion Control Algorithms, i.e. Slow Start, Cogestion Avoidance, Fast Retransmit and Fast Recovery?

 

Also, if feasible, is it possible to recompile the kernel disabling congestion control? Are there specific settings to enable/disable congestion control in NetBSD?

 

Your help will be much appreciated, thank you.

 

Regards,

Abraham
