Thomas Graf | 52ab4ac | 2005-11-01 15:13:02 +0100 | [diff] [blame] | 11 | delay, and which ones to drop. This is the job of the queueing |

| 15 | If you say N here, you will get the standard packet scheduler, which |
| 16 | is a FIFO (first come, first served). If you say Y here, you will be |
| 17 | able to choose from among several alternative algorithms which can |
| 18 | then be attached to different network devices. This is useful for |
| 19 | example if some of your network devices are real time devices that |
| 20 | need a certain minimum data flow rate, or if you need to limit the |
| 21 | maximum data flow rate for traffic which matches specified criteria. |
| 22 | This code is considered to be experimental. |

| 333 | This queuing discipline allows userspace to plug/unplug a network |
| 334 | output queue, using the netlink interface. When it receives an |
| 335 | enqueue command it inserts a plug into the outbound queue that |
| 336 | causes following packets to enqueue until a dequeue command arrives |
| 337 | over netlink, causing the plug to be removed and resuming the normal |
| 338 | packet flow. |
| 339 | |
| 340 | This module also provides a generic "network output buffering" |
| 341 | functionality (aka output commit), wherein upon arrival of a dequeue |
| 342 | command, only packets up to the first plug are released for delivery. |
