dummynet

DUMMYNET(4)						   BSD Kernel Interfaces Manual 					       DUMMYNET(4)

NAME

     dummynet -- traffic shaper, bandwidth manager and delay emulator

DESCRIPTION

     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.

     The user interface for dummynet is implemented by the dnctl program, so the reader is referred to the dnctl(8) manpage for a complete
     description of the capabilities of dummynet and on how to use it.

SEE ALSO

     dnctl(8), setsockopt(2), bridge(4), ip(4), sysctl(8)

HISTORY

     dummynet was initially implemented as a testing tool for TCP congestion control by Luigi Rizzo <luigi@iet.unipi.it>, as described on ACM Com-
     puter 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.
