![]() Encoding using these standards can happen for the entire session, which is ideal for full-screen motion, or selectively to certain regions with motion as required. The end result is a highly responsive session for a wide range of client endpoints.Ĭitrix display optimizations make use of both H.264 and H.265 codecs for superior image quality with minimal bandwidth consumption. Adaptive Transport allows sessions to seamlessly switch between EDT/UDP and TCP as needed without any configuration required. This display optimization is accomplished through Citrix’s Enlightened Data Transport (EDT) Protocol which makes intelligent, reliable use of UDP for optimum performance. HDX Adaptive Transport ensures that all functions within user sessions perform well, including graphics, even as network characteristics change. HDX technologies deliver bandwidth-efficient multimedia and video through the use of policies and templates-and they do it with exceptional display optimization. Users expect app and desktop delivery solutions to have near real-time audio and multimedia characteristics-similar to those they receive from local app and desktop implementations. HDX also supports multicasting of multimedia streams, where a single transmission from the source is viewed by multiple “subscribers” at one location, rather than a one-to-one connection for each user. Caching these patterns allows only the changes to be transmitted across the network, eliminating duplicate traffic. De-duplication of network trafficĭe-duplication of network traffic reduces the aggregate data sent between client and server by taking advantage of repeated patterns in commonly accessed data such as bitmap graphics, documents, print jobs, and streamed media. It then intelligently adapts based on each unique user or session. Next, it chooses the optimal compression codec and the best proportion of CPU or GPU utilization. ![]() HDX first evaluates variables such as the type of input, device, and display (text, video, voice, multimedia). Adaptive compressionĪdaptive compression is a core intellectual property of the ICA protocol which allows rich multimedia displays to be delivered on thin network connections. 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. Rendering can occur on either the endpoint device or hosting server.Ĭlient redirection leverages processing power on endpoints, if available, to free up the server to handle other processes or more users. Intelligent redirection examines screen activity, application commands, endpoint devices, and network and server capabilities to instantly determine how and where to render an application or desktop activity.

A central component of Citrix DaaS, HDX ensures users have a consistent experience across a wide array of devices and networks. Built on top of the Independent Computing Architecture (ICA) remoting protocol, it’s used by global enterprises to support millions of users. Citrix HDX is a suite of proprietary technologies that delivers a high-definition experience to users of virtual desktops and virtual applications.
