They are the -simplest queues possible and therefore have no overhead. -.B pfifo -constrains the queue size as measured in packets. -.B bfifo -does so as measured in bytes. - -Like all non-default qdiscs, they maintain statistics. This might be a reason to prefer -pfifo or bfifo over the default. - -.SH ALGORITHM -A list of packets is maintained, when a packet is enqueued it gets inserted at the tail of -a list. When a packet needs to be sent out to the network, it is taken from the head of the list. - -If the list is too long, no further packets are allowed on. This is called 'tail drop'. - -.SH PARAMETERS -.TP -limit -Maximum queue size. Specified in bytes for bfifo, in packets for pfifo. For pfifo, defaults -to the interface txqueuelen, as specified with -.BR ifconfig (8) -or -.BR ip (8). - -For bfifo, it defaults to the txqueuelen multiplied by the interface MTU. - -.SH OUTPUT -The output of -.B tc -s qdisc ls -contains the limit, either in packets or in bytes, and the number of bytes -and packets actually sent. An unsent and dropped packet only appears between braces -and is not counted as 'Sent'. - -In this example, the queue length is 100 packets, 45894 bytes were sent over 681 packets. -No packets were dropped, and as the pfifo queue does not slow down packets, there were also no -overlimits: -.P -.nf -# tc -s qdisc ls dev eth0 -qdisc pfifo 8001: dev eth0 limit 100p - Sent 45894 bytes 681 pkts (dropped 0, overlimits 0) -.fi - -If a backlog occurs, this is displayed as well. -.SH SEE ALSO -.BR tc (8) - -.SH AUTHORS -Alexey N.
