5.2.2.4 QoS/DSCP (Quality of Server/Differentiated Services Code-point)
DSCP specifies a simple mechanism for classifying and managing network traffic and provide 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 items 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).
The three stream control the protocols respectively:
• Live Stream (Video and audio): RTP / RTSP
• Event/Alarm : FTP / SMTP / SAMBA / SIP
• Management: HTTPS / HTTP / SNMP
The "Management" stream handles both the live view and the setting area of
the web page on which the data is transferred via http/https protocol. If you
prefer to distribute more bandwidth when using the web browser to access
the camera, please adjust the Management stream.
