"Citrix HDX technologies address the full range of application performance and network challenges presented by virtualization. With HDX technologies, Citrix XenApp and Citrix XenDesktop deliver a brilliant user experience on a wide variety of devices and network connections, equaling or surpassing the local PC experience"


Introducing HDX technologies

         HDX technologies offer a set of capabilities that deliver a "high-definition" experience to users of Windows applications and desktops, on any device and over any network. HDX technologies are built on top of the Citrix® ICA® remoting protocol, renowned for best-of-breed networking and representing more than 20 years of innovation. The ICA protocol is based on TCP/IP and RTP/UDP and is uniquely designed to traverse difficult network topologies such as mobile networks with high variability and low-bandwidth WANs with high latency characteristics.

Underpinning HDX are three technical principles - intelligent redirection, adaptive compression and data de-duplication - which work in concert to optimize the user experience, decrease bandwidth consumption and increase the scalability of the hosting server.

Deliver smooth voice, video and multimedia performance

         Users expect app and desktop virtualization solutions to provide the same audio and multimedia reliability they receive from non-virtual desktop implementations. HDX technologies deliver bandwidth-efficient, crystal-clear voice, multimedia and video.

Enhancing thin clients with HDX SoC embedded technology

         Citrix provides an SDK to system-on-chip (SoC) vendors that enables compute-intensive HDX algorithms to execute outboard from the CPU, allowing inexpensive ARM processor-based devices to deliver a high-definition user experience. Device manufacturers using these SoCs have now brought to market a broad portfolio of low-cost HDX Ready thin clients, zero clients and other products. Unlike competing solutions that burn the remoting protocol into silicon, which can result in device obsolescence within months, the Citrix approach supports ongoing innovation without hardware replacement.

Accelerating printing and scanning

         Citrix supports both local USB and network printing. Local printing entails redirecting and terminating the printer locally to allow the user to interact with it at native USB speeds. Network-based printing is supported using Citrix Universal Print Server and Universal Print Driver technologies.

XenApp, XenDesktop and HDX technology

         HDX technologies are the foundation of the Citrix apps and desktop delivery platform, which provides superior virtual app and desktop solution accessible from any device, over any network and gives end users an application and desktop experience that rivals that of a local PC-even when people are using multimedia, real-time collaboration, USB peripherals and 3D graphics apps over low-bandwidth, high-latency networks. With XenApp and XenDesktop and HDX technologies, IT can successfully extend delivery of virtual apps and desktops beyond the corporate HQ to remote, mobile and branch office users.
