Your lucky day, Brian. Turns out there are a ton of new TCP commands that came out in 11.6. I will get the wiki updated when I get the full documentation, but here's the list:

 

  • TCP::delayed_ack enable | disable
  • TCP::dsack enable | disable
  • TCP::abc enable | disable
  • TCP::pacing enable | disable
  • TCP::limxmit enable | disable
  • TCP::ecn enable | disable
  • TCP::idletime timeval
  • TCP::autowin enable | disable
  • TCP::congestion None | Reno | Newreno | HighSpeed | Scalable | Vegas | CDG | CHD | Illinois | Woodside | Cubic | Westwood+
  • TCP::lossfilter rate burst
  • TCP::sendbuf size
  • TCP::recvwnd size
  • TCP::proxybuffer high low
  • TCP::setmss mssval

Looks like with all these settings, you can essentially create a procs library of "profiles" to switch programmatically base on your traffic analysis.
