FreeBSD" FreeBSD Foundation funded project. - Add new man pages for the modular congestion control, Khelp and Hhook frameworks (cc.4, cc.9, khelp.9 and hhook.9). - Add new man pages for each available congestion control algorithm (cc_chd.4, cc_cubic.4, cc_hd.4, cc_htcp.4, cc_newreno.4 and cc_vegas.4). - Add a new man page for the Enhanced Round Trip Time (ERTT) Khelp module (h_ertt.4). - Update the TCP (tcp.4) man page to mention the TCP_CONGESTION socket option, cross reference to cc.4 and remove references to the retired "net.inet.tcp.newreno" sysctl MIB variable. In collaboration with: David Hayes <dahayes at swin edu au> and Grenville Armitage <garmitage at swin edu au> Sponsored by: FreeBSD Foundation MFC after: 3 months

|
|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
congestion control algorithm first appeared in its modular form in
|
|
.Fx 9.0 .
|
|
.Pp
|
|
The module was first released in 2007 by James Healy and Lawrence Stewart whilst
|
|
working on the NewTCP research project at Swinburne University's Centre for
|
|
Advanced Internet Architectures, Melbourne, Australia, which was made possible
|
|
in part by a grant from the Cisco University Research Program Fund at Community
|
|
Foundation Silicon Valley.
