DSCP Marking for MSRP and Media Over TCP
The Oracle Communications Session Border Controller supports Differentiated Services Code Point (DSCP) marking of MSRP and Media over TCP traffic. This feature may be used for MSRP traffic in both B2BUA and non-B2BUA modes.
In order to configure the Oracle Communications Session Border Controller to mark MSRP or media over TCP packets with a value in the IP header's DSCP field, create a media-manager, media-policy, tos-settings configuration element and set the media-type parameter to message. This has the effect of marking all traffic described by prior SDP with m=message with this DSCP value.
Note that setting
media-type to
message can
potentially mark a large range of traffic. For other common traffic to remain
marked differently than marked MSRP, you need to create additional
tos-settings
configuration elements with valid
media-sub-type
configurations. The following values may be provisioned in the
media-sub-type
parameter to mark these other types of traffic differently (with an
accompanying
tos-value).
