Zoom Integration Update

By March 22, 2021 March 25th, 2021 News, Tech Tips

The Calyx engineering team recently completed the integration of the Zoom optimization pack within the Framework platform. This enables you to run your Zoom video meetings directly within your Framework Desktop, eliminating the need to access your local device. This optimization utilizes Citrix Virtual Channel SDK and Citrix HDX technologies to allow streaming video and audio without delay or loss of quality while reducing bandwidth consumption. 

Important Note: 
Our team must install and configure the Zoom software plugin on your local devices for this new feature to function. Interested in the Zoom Integration for Framework? Please email help@calyxIT.com and let our team know that you would like the Zoom integration enabled for you and your staff. They will schedule the work to occur off-hours. We’ll fulfill your request within 7-10 days.

About Citrix Virtual Channel SDX

A Citrix virtual channel is a bi-directional, reliable connection used to exchange generalized packet data between a Citrix host (XenApp or XenDesktop) and Citrix Receiver on end-user devices. Sound, graphics, client drive mapping and printing, for example, are just a few of the virtual channels written by Citrix.

The Citrix Virtual Channel Software Development Kit (VCSDK) allows software engineers to write host-side applications and Citrix Receiver-side drivers to support additional virtual channels using the Citrix ICA protocol. Host-side virtual channel applications run on XenApp or XenDesktop, and the client-side portion of the virtual channel runs on the local device where Citrix Receiver resides. This SDK provides support for writing new virtual channels for the Win32, Linux and Mac OSX versions of Citrix Receiver.

About Citrix HDX

HDX technology delivers a “high-definition” experience to users of centralized applications and desktops, on any device and over any network. HDX is built on the Independent Computing Architecture (ICA) remoting protocol. It is renowned for best-of-breed networking and representing over 20 years of innovation. It is proven in large enterprise environments and accessed by millions of users globally.


HDX is designed around three technical principles: intelligent redirection, adaptive compression, and data de-duplication. Applied in different combinations, they are designed to optimize the IT and user experience, decrease bandwidth consumption, and increase hosting server density. 

What are the three technical principles behind HDX Technology?

1. Intelligent redirection

Intelligent redirection examines screen activity, application commands, endpoint device, and network and server capabilities. It instantly determines how and where to render an application or desktop activity. Rendering can occur on either the endpoint device or hosting server. Client redirection leverages processing power on endpoints, if available, to free up the server to handle other processes or more users. Device redirection intercepts peripherals such as webcams, printers, scanners, digital pens, and 3D mice at a local level to allow users to interact with these devices in sessions.

2. Adaptive compression

Adaptive compression, a core intellectual property of the ICA protocol, enables rich multimedia displays to be delivered on thin network connections. HDX first evaluates a number of variables —such as the type of input, device, and display (text, video, voice, multimedia). Next, it chooses the optimal compression codec and the best proportion of CPU and/or GPU utilization. Then, it intelligently adapts based on each unique user and basis. This is intelligently adapted per user or per-session.

3. De-duplication of network traffic

De-duplication of network traffic reduces the aggregate data sent between client and server. It takes advantage of repeated patterns in commonly accessed data such as bitmap graphics, documents, print jobs and streamed media. Caching these patterns allows only the changes to be transmitted across the network, eliminating duplicate traffic. HDX also supports multicasting of multimedia streams. A single transmission from the source is viewed by multiple “subscribers” at one location, rather than a one-to-one connection per user.
