Traffic S haping
Traffic shaping is used to control the traffic of ingress/egress based on each network port.
As shown in figure 24, the ingress of ath0 is limited to 1024K bps, and the egress is limited
to 2048Kbps. That means the receiving rate of the wireless link is limited within 1Mbps,
the sending rate is limited to less than 2Mbps. But usually, the input limited effect is not
obviously, that’s because we could not control how quickly the traffic arrives. H owever,
when a port sends out egress traffic, it can control how quickly the traffic exits.
Burst defines the how many bytes allowed for downloading/uploading during a quick time.
That leads to momentary throughput can greater than the limit value.
Figure 24 Traffic S haping
Ingress traffic entering ath0, control the input rate
Egress traffic exiting ath0, control the output rate
The relationship of rate and burst for ingress:
S et burst to 0, the rate of ingress is unlimited
S et burst to about 1/10 of rate limit, the rate curve is stable
S et burst larger than rate limit, the rate curve will hold a high value for a while then down to
stable
Below is the table that reflects the relationship between ingress rate limit and burst.
