Question

Your organization has enabled RDP Shortpath for managed networks so that AVD session traffic flows over UDP. Users on a congested WAN link report choppy audio and laggy screen updates during peak hours. Network engineers want to prioritize the AVD real-time traffic across QoS-enabled routers. What must you configure so that AVD UDP traffic is correctly tagged for QoS prioritization end to end?

Accepted Answer

Create a Group Policy QoS policy that marks the session host's outbound RDP UDP traffic with DSCP value 46 (Expedited Forwarding) for the Shortpath port range.

Answer

Enable Accelerated Networking on the session host NICs so the UDP packets are automatically tagged with the correct DSCP value.

Answer

Configure a network security group (NSG) rule that sets a priority value on the inbound UDP 3390 traffic to the session hosts.

Answer

Apply an Azure Firewall application rule that rewrites the DSCP header of AVD traffic to Expedited Forwarding as it leaves the VNet.
