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 | |
52ab4ac2 TG |
12 | delay, and which ones to drop. This is the job of the queueing |
13 | disciplines, several different algorithms for how to do this | |
6a2e9b73 SR |
14 | "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 | |
5d330cdd AS |
26 | from the package iproute2+tc at |
27 | <https://www.kernel.org/pub/linux/utils/net/iproute2/>. That package | |
28 | also contains some documentation; for more, check out | |
c996d8b9 | 29 | <http://www.linuxfoundation.org/collaborate/workgroups/networking/iproute2>. |

31 | This Quality of Service (QoS) support will enable you to use | |
32 | Differentiated Services (diffserv) and Resource Reservation Protocol | |
52ab4ac2 TG |
33 | (RSVP) on your Linux router if you also say Y to the corresponding |
34 | classifiers below. Documentation and software is at | |
35 | <http://diffserv.sourceforge.net/>. | |
6a2e9b73 SR |
36 | |
37 | If you say Y here and to "/proc file system" below, you will be able | |
38 | to read status information about packet schedulers from the file | |
39 | /proc/net/psched. | |
40 | ||
41 | The available schedulers are listed in the following questions; you | |
42 | can say Y to as many as you like. If unsure, say N now. | |
