How the DSCP Marking Works for 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 that is based on 5QI+ARP combination.

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

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

  • Allows implementation of associated DSCP marking for 5QI+ARP for Uplink and Downlink functionality.
