This month’s XenApp and XenDesktop 7.12 release includes a preview of the next-generation data transport engine for HDX, engineered for Cloud computing. We’ve carefully selected techniques that were previously available only with Framehawk to boost throughput on high-latency network connections for all ICA virtual channels including Thinwire display remoting, printing, audio-video and more. With Adaptive Transport, Citrix engineers have, in effect, put a high-torque electric engine into the HDX technology stack to accelerate user experience while maintaining low TCO.

Step on the accelerator and feel the power! Take a look under the hood! (or “bonnet”, depending on your locale). The preview release of our new “enlightened” data transport engine provides an early look into the next generation of XenApp and XenDesktop user experience technologies. We’re bringing performance like that of a high-end hybrid-electric sports car to all users of Cloud-hosted apps and desktops. Our own internal testing has shown remarkable improvements in UI responsiveness at high network latency and dramatic increases in the speed of file transfers and print jobs. But we want you to test drive this new technology yourself, at transcontinental and intercontinental latencies and beyond, and share your observations with us and with the Citrix community.

You can immediately evaluate this next-generation HDX technology on your corporate WAN (or with a WAN emulator) to see how it handles high network latencies, even with moderate packet loss. And soon you will also be able to evaluate it with NetScaler Gateway to see how it benefits off-net workers such as work-from-home employees.

Here’s what we think you’ll find:

  1. Outstanding interactivity at high latency
  2. Low TCO through compatibility with Thinwire display remoting and multimedia redirection for bandwidth efficiency and server scalability
  3. Faster performance for all virtual channels, including Printing and Client Drive Mapping (file transfers)
  4. Adaptive optimization as network conditions change
  5. Minimal change to existing infrastructure, supporting the popular Receiver versions (with more to follow) and security gateways

We’ll eagerly watch for your feedback on our Discussions Forum.

Buckle up and enjoy your test drive! And stay tuned for my next blog post where I’ll provide an in-depth consideration of approaches for reducing end-to-end latency with virtual apps and desktops.
