  18. When the kernel has several packets to send out over a network
  19. device, it has to decide which ones to send first, which ones to
  20. delay, and which ones to drop. This is the job of the queueing
  21. disciplines, several different algorithms for how to do this
  22. "fairly" have been proposed.
  23. If you say N here, you will get the standard packet scheduler, which
  24. is a FIFO (first come, first served). If you say Y here, you will be
  25. able to choose from among several alternative algorithms which can
  26. then be attached to different network devices. This is useful for
  27. example if some of your network devices are real time devices that
  28. need a certain minimum data flow rate, or if you need to limit the
  29. maximum data flow rate for traffic which matches specified criteria.
  30. This code is considered to be experimental.
  31. To administer these schedulers, you'll need the user-level utilities
  32. from the package iproute2+tc at <ftp://ftp.tux.org/pub/net/ip-routing/>.
  33. That package also contains some documentation; for more, check out
  34. <http://linux-net.osdl.org/index.php/Iproute2>.
  35. This Quality of Service (QoS) support will enable you to use
  36. Differentiated Services (diffserv) and Resource Reservation Protocol
  37. (RSVP) on your Linux router if you also say Y to the corresponding
  38. classifiers below. Documentation and software is at
  39. <http://diffserv.sourceforge.net/>.

  47. Say Y here if you want to use the Class-Based Queueing (CBQ) packet
  48. scheduling algorithm. This algorithm classifies the waiting packets
  49. into a tree-like hierarchy of classes; the leaves of this tree are
  50. in turn scheduled by separate algorithms.
  51. See the top of <file:net/sched/sch_cbq.c> for more details.
  52. CBQ is a commonly used scheduler, so if you're unsure, you should
  53. say Y here. Then say Y to all the queueing algorithms below that you
  54. want to use as leaf disciplines.
