Feature description
RDP Shortpath establishes direct UDP-based connection between a remote desktop client and session host. Direct connection reduces the dependency on the Azure Virtual Desktop gateways, improves the connection reliability, and increases the bandwidth available for each user session.
To enable AVD Shortpath, please check the box "Manage RDP Shortpath" in the RAS Console > Farm > AVD > Host pools > Host pool properties
Use case
UDP over TCP gives better overal performance in a session, including round-trip latency, image quality and usually the best option to give better user experince. On the other hand, TCP has embedded features which provide error check and its restoration under bad network conditions.
| Transport | Latency | Performance | Error check | Self-recovery |
| UDP | + | + | - | - |
| TCP | - | - | + | + |
There are the following ways to verify which protocol is utilized by RAS session:
- RAS Console > Sessions > double-click on the user session.
