Adaptive transport

Previously available as an experimental feature, adaptive transport is a fully supported feature in this release.

Adaptive transport is a data transport mechanism for Citrix Virtual Apps and Desktops. It is faster, more scalable, improves application interactivity, and is more interactive on challenging long-haul WAN and internet connections. For more information about adaptive transport, see Adaptive transport.

Enable adaptive transport

In Citrix Studio, verify that the HDX Adaptive Transport policy is set to Preferred or Diagnostic mode. Preferred is selected by default.

  • Preferred: Adaptive transport over Enlightened Data Transport (EDT) is used when possible, with fallback to TCP.
  • Diagnostic mode: EDT is forced on and fallback to TCP is disabled.

Disable adaptive transport

To disable adaptive transport, set the HDX Adaptive Transport policy to Off in Citrix Studio.

Troubleshooting

Check whether adaptive transport is enabled

To check whether UDP listeners are running, run the following command.

netstat -an | grep "1494\|2598"

In normal circumstances, the output is similar to the following.

udp        0      0 0.0.0.0:2598            0.0.0.0:*

udp       0      0 :::1494                 :::*
