Quality Service
Quality Service provides network traffic management to guarantee the quality of services in higher priority,
especially when network is insufficient. DSCP (Different Service Code Point) is a 6-bit IP header which defines
the service level of the packet. According to the DSCP value, routers with PHB (Per-Hop Behavior) will define
a specific class of traffic for the packet, in terms of bandwidth, latency, or loss rate, etc. Enable QoS and set
DSCP value for the service to ensure its quality to be maintained.
NOTE
To make the QoS function work, all the switches and routers in the network must support QoS.
