RealTime Optimization Pack 2.4 (LTSR)
The Long Term Service Release (LTSR) program for the HDX RealTime Optimization Pack provides stability and long-term support for the HDX RealTime Optimization Pack 2.4 release.
In addition, Citrix also recommends specific versions of Citrix Receiver and other components. While not required for LTSR compliance, upgrading to the current versions, latest LTSR or LTSR Cumulative Update (CU), or Microsoft equivalent of those components ensures further ease of maintenance and the availability of the latest fixes in your deployment.

HDX RealTime Optimization Pack provides a scalable solution for delivering audio-video conferencing and Voice over Internet Protocol enterprise telephony through Microsoft Skype for Business. The Optimization Pack supports XenDesktop and XenApp environments to users on Linux, Mac, Windows, and (through a partnership with Dell) Wyse ThinOS devices. The Optimization Pack uses your existing Microsoft Skype for Business infrastructure, on premises or in the cloud, and inter-operates with other Microsoft Skype for Business endpoints running natively on devices.
The Optimization Pack consists of both client and server components:
- Client component. Citrix HDX RealTime Media Engine and Citrix Receiver integrate on the endpoint device and performs media processing directly on the user device. It offloads the server for maximum scalability, minimizing network bandwidth consumption, and ensuring optimal audio-video quality.
The RealTime Optimization Pack Capability Checker for Windows determines endpoint ability to support the Optimization Pack. For information, see https://support.citrix.com/article/CTX222459.
- Server-side (and virtual desktop) component. Citrix HDX RealTime Connector is a connector to the virtualized Microsoft Skype for Business client running on the XenApp or XenDesktop server. It drives the RealTime Media Engine on the endpoint. RealTime Connector runs in the virtual server environment alongside Microsoft Skype for Business. It communicates signaling information over a Citrix ICA virtual channel to the RealTime Media Engine running on the user device.
The Optimization Pack supports users who are on the corporate network or working remotely. For information about configuring secure remote access to Skype for Business using the HDX RealTime Optimization Pack, see https://support.citrix.com/article/CTX201116.
