d. 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.
Set up instruction:
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. The item getting more bandwidth has lower probability to be
delayed. 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
Note: 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 watch the live video, please adjust the Management Stream
instead of Live Stream.
