| bool "QoS and/or fair queueing" |
| select NET_SCH_FIFO |
| help |
| When the kernel has several packets to send out over a network |
| device, it has to decide which ones to send first, which ones to |
| delay, and which ones to drop. This is the job of the queueing |
| disciplines, several different algorithms for how to do this |
| "fairly" have been proposed. |
| |
| If you say N here, you will get the standard packet scheduler, which |
| is a FIFO (first come, first served). If you say Y here, you will be |
| able to choose from among several alternative algorithms which can |
| then be attached to different network devices. This is useful for |
| example if some of your network devices are real time devices that |
| need a certain minimum data flow rate, or if you need to limit the |
| maximum data flow rate for traffic which matches specified criteria. |
| This code is considered to be experimental. |
| |
| To administer these schedulers, you'll need the user-level utilities |
| from the package iproute2+tc at |
| <https://www.kernel.org/pub/linux/utils/net/iproute2/>. That package |
| also contains some documentation; for more, check out |
| <http://www.linuxfoundation.org/collaborate/workgroups/networking/iproute2>. |
| |
| This Quality of Service (QoS) support will enable you to use |
| Differentiated Services (diffserv) and Resource Reservation Protocol |
| (RSVP) on your Linux router if you also say Y to the corresponding |
| classifiers below. Documentation and software is at |
| <http://diffserv.sourceforge.net/>. |
| |
| If you say Y here and to "/proc file system" below, you will be able |
| to read status information about packet schedulers from the file |
| /proc/net/psched. |

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