QoS Configuration
DSCP tags set packet priorities for QoS.
DSCP Tag
DSCP (Differentiated Services Code Point) is a QoS mechanism for setting
relative priorities. Packets are tagged with a DSCP field in the IP header. The
decimal value may be set as a number from 0-63 and may be different for each
traffic class listed on the screen.
•
Administration
tags set the priority for telnet, TFTP, and other
administrative traffic. Administrative traffic can have the lowest priority
because it does not require voice quality.
•
WT (In call)
traffic requires voice quality and may be set to a higher
priority than
WT
(
Standby
) traffic.
•
RTP
traffic is the audio traffic to the IP PBX. It requires voice quality.
•
PBX
traffic is not audio to the PBX.
•
Inter-SVP2
traffic is the information-passing protocol that SVP Servers
use to communicate with each other.
When forwarding packets, the SVP Server shall always overwrite the received
DSCP value. The final DSCP tag for packets in each of the traffic classes are
assigned a DSCP value based on the following rules. (Please see table on next
page.)
• If both
Administration
and the
Traffic
Class
setting is
Default
, the
Default
value as shown in the table below will be used.
• If
Administration
is set at any number (
Value
X
) other than
Default
, that
setting (
Value X
) it will override the
Default
value of the
Traffic
Class
.
