9 When the kernel has several packets to send out over a network
10 device, it has to decide which ones to send first, which ones to
Thomas Graf52ab4ac2005-11-01 15:13:02 +010011 delay, and which ones to drop. This is the job of the queueing
12 disciplines, several different algorithms for how to do this
Sam Ravnborg6a2e9b72005-07-11 21:13:56 -070013 "fairly" have been proposed.
14
15 If you say N here, you will get the standard packet scheduler, which
16 is a FIFO (first come, first served). If you say Y here, you will be
17 able to choose from among several alternative algorithms which can
18 then be attached to different network devices. This is useful for
19 example if some of your network devices are real time devices that
20 need a certain minimum data flow rate, or if you need to limit the
21 maximum data flow rate for traffic which matches specified criteria.
22 This code is considered to be experimental.
23
24 To administer these schedulers, you'll need the user-level utilities
25 from the package iproute2+tc at <ftp://ftp.tux.org/pub/net/ip-routing/>.
26 That package also contains some documentation; for more, check out
Michael Wittenc996d8b2010-11-15 19:55:34 +000027 <http://www.linuxfoundation.org/collaborate/workgroups/networking/iproute2>.

Sam Ravnborg6a2e9b72005-07-11 21:13:56 -070034
35 If you say Y here and to "/proc file system" below, you will be able
36 to read status information about packet schedulers from the file
37 /proc/net/psched.
38
39 The available schedulers are listed in the following questions; you
40 can say Y to as many as you like. If unsure, say N now.
