If another qdisc is attached, it preempts the default -pfifo_fast, which automatically returns to function when an existing qdisc -is detached. - -In this sense this qdisc is magic, and unlike other qdiscs. - -.SH ALGORITHM -The algorithm is very similar to that of the classful -.BR tc-prio (8) -qdisc. -.B pfifo_fast -is like three -.BR tc-pfifo (8) -queues side by side, where packets can be enqueued in any of the three bands -based on their Type of Service bits or assigned priority. - -Not all three bands are dequeued simultaneously - as long as lower bands -have traffic, higher bands are never dequeued. This can be used to -prioritize interactive traffic or penalize 'lowest cost' traffic. - -Each band can be txqueuelen packets long, as configured with -.BR ifconfig (8) -or -.BR ip (8). -Additional packets coming in are not enqueued but are instead dropped. - -See -.BR tc-prio (8) -for complete details on how TOS bits are translated into bands. -.SH PARAMETERS -.TP -txqueuelen -The length of the three bands depends on the interface txqueuelen, as -specified with -.BR ifconfig (8) -or -.BR ip (8). - -.SH BUGS -Does not maintain statistics and does not show up in tc qdisc ls. This is because -it is the automatic default in the absence of a configured qdisc. - -.SH SEE ALSO -.BR tc (8) - -.SH AUTHORS -Alexey N. Kuznetsov, - -This manpage maintained by bert hubert - -
