Page 27 DH-PFM880 User Manual DaHua All Right Reserved 7.6 Static Routes This feature can be set to static routing. 7.7 Traffic Shaping Traffic shaping is used to control the traffic of ingress/egress based on each network port. As shown in figure 24, the ingress of wlan0 is limited to 1024Kbps, 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, thats because we could not control how quickly the traffic arrives. However, 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.
