Usage Guidelines
DSCP levels can be assigned to specific traffic patterns in order to ensure that data packets are delivered
according to the precedence with which they're tagged. The diffserv markings are applied to the IP header of
every subscriber data packet transmitted over the Gn' interface(s).
The four traffic patterns have the following order of precedence: background (lowest), interactive, streaming,
and conversational (highest). Data packets falling under the category of each of the traffic patterns are tagged
with a DSCP that further indicate their precedence as shown in the following tables:
