QoS/DSCP
(Quality of Server/Differentiated Services Code-point) specifies a simple mechanism for
classifying and managing network traffic and provides QoS on IP networks. DSCP is a 6-bit in the IP
header for packet classification purpose. The number 0~63 for Live Stream, Event / Alarm, and
Management represent the ratio that the bandwidth is divided. For example, if you set 5, 10, and 20 for
the three items, then the bandwidth of the three item is 5:10:20. There is no difference between setting
"0, 0, 0" or "63, 63, 63" because under these two setting the three items will get equal bandwidth (1/3).
