10 When the kernel has several packets to send out over a network
11 device, it has to decide which ones to send first, which ones to
Thomas Graf52ab4ac2005-11-01 15:13:02 +010012 delay, and which ones to drop. This is the job of the queueing
13 disciplines, several different algorithms for how to do this
Sam Ravnborg6a2e9b72005-07-11 21:13:56 -070014 "fairly" have been proposed.
15
16 If you say N here, you will get the standard packet scheduler, which
17 is a FIFO (first come, first served). If you say Y here, you will be
18 able to choose from among several alternative algorithms which can
19 then be attached to different network devices. This is useful for
20 example if some of your network devices are real time devices that
21 need a certain minimum data flow rate, or if you need to limit the
22 maximum data flow rate for traffic which matches specified criteria.
23 This code is considered to be experimental.
24
25 To administer these schedulers, you'll need the user-level utilities
26 from the package iproute2+tc at <ftp://ftp.tux.org/pub/net/ip-routing/>.
27 That package also contains some documentation; for more, check out

36 If you say Y here and to "/proc file system" below, you will be able
37 to read status information about packet schedulers from the file

40 The available schedulers are listed in the following questions; you
41 can say Y to as many as you like. If unsure, say N now.
