.Sh NAME
.Nm dummynet
.Nd traffic shaper, bandwidth manager and delay emulator
.Sh DESCRIPTION
.Em dummynet
is a system facility that permits the control of traffic
going through the various network interfaces, by applying bandwidth
and queue size limitations, implementing different scheduling and queue
management policies, and emulating delays and losses.
.Pp
The user interface for
.Em dummynet
is implemented by the
.Nm dnctl
program, so the reader is referred to the
.Xr dnctl 8
manpage for a complete description of the capabilities of
.Nm
and on how to use it.
.Sh SEE ALSO
.Xr dnctl 8 ,
.Xr setsockopt 2 ,
.Xr bridge 4 ,
.Xr ip 4 ,
.Xr sysctl 8
.Sh HISTORY
.Nm
was initially implemented as a testing tool for TCP congestion control
by
.An Luigi Rizzo Aq luigi@iet.unipi.it ,
as described on ACM Computer Communication Review, Jan.97 issue.
Later it has been then modified to work at the ip and bridging
level, integrated with the IPFW packet filter, and extended to
support multiple queueing and scheduling policies.
