96a2e9b73SSam Ravnborg	  When the kernel has several packets to send out over a network
106a2e9b73SSam Ravnborg	  device, it has to decide which ones to send first, which ones to
1152ab4ac2SThomas Graf	  delay, and which ones to drop. This is the job of the queueing
1252ab4ac2SThomas Graf	  disciplines, several different algorithms for how to do this
136a2e9b73SSam Ravnborg	  "fairly" have been proposed.
146a2e9b73SSam Ravnborg
156a2e9b73SSam Ravnborg	  If you say N here, you will get the standard packet scheduler, which
166a2e9b73SSam Ravnborg	  is a FIFO (first come, first served). If you say Y here, you will be
176a2e9b73SSam Ravnborg	  able to choose from among several alternative algorithms which can
186a2e9b73SSam Ravnborg	  then be attached to different network devices. This is useful for
196a2e9b73SSam Ravnborg	  example if some of your network devices are real time devices that
206a2e9b73SSam Ravnborg	  need a certain minimum data flow rate, or if you need to limit the
216a2e9b73SSam Ravnborg	  maximum data flow rate for traffic which matches specified criteria.
226a2e9b73SSam Ravnborg	  This code is considered to be experimental.
236a2e9b73SSam Ravnborg
246a2e9b73SSam Ravnborg	  To administer these schedulers, you'll need the user-level utilities
255d330cddSAndrew Shewmaker	  from the package iproute2+tc at
265d330cddSAndrew Shewmaker	  <https://www.kernel.org/pub/linux/utils/net/iproute2/>.  That package
275d330cddSAndrew Shewmaker	  also contains some documentation; for more, check out

316a2e9b73SSam Ravnborg	  Differentiated Services (diffserv) and Resource Reservation Protocol
3252ab4ac2SThomas Graf	  (RSVP) on your Linux router if you also say Y to the corresponding
3352ab4ac2SThomas Graf	  classifiers below.  Documentation and software is at
3452ab4ac2SThomas Graf	  <http://diffserv.sourceforge.net/>.
356a2e9b73SSam Ravnborg
366a2e9b73SSam Ravnborg	  If you say Y here and to "/proc file system" below, you will be able
376a2e9b73SSam Ravnborg	  to read status information about packet schedulers from the file
386a2e9b73SSam Ravnborg	  /proc/net/psched.
396a2e9b73SSam Ravnborg
406a2e9b73SSam Ravnborg	  The available schedulers are listed in the following questions; you
416a2e9b73SSam Ravnborg	  can say Y to as many as you like. If unsure, say N now.
