Hi,
If I write the value of a tunable parameter to the /proc/web100/<cid>
file, how soon after that will the TCP stack be able to see and use this
value. I am trying to add a tunable parameter to set the initial cwnd. For
now I am using MaxSsthresh WAD parameter for setting the init cwnd value
and setting cwnd to MaxSsthresh in tcp_input.c:reno_cong_avoid(). I was
expecting that TCP would be able to use the init cwnd value as soon as it
gets an ACK after the init cwnd value has been written to the
/proc/web100/<cid> file, but that's not happening.
Would anyone could tell me how a value written to /proc/web100/<cid> gets
stored in the web100stats structure of the tcp_opt structure and how soon
it is available to the TCP stack?
Thanks,
Anant.
