How the DSCP Marking Works for Data Packets

This section describes how the DSCP marking can be performed for the data packets.

Allocation of different DSCP values for flows with the same 5QI, but different ARP values, works as follows:

  • Allows DSCP marking of packets based on 5QI and ARP combination.

  • 5QI and ARP configuration overrides any pre-entry of DSCP marking of packets that was based on 5QI and ARP combination.

  • 5QI-only DSCP entry overrides all the existing 5QI and ARP configuration.

  • Allows implementation of associated DSCP marking for 5QI and ARP for uplink and downlink traffic.
