Delivering a High Definition User Experience
The Citrix HDX Philosophy
1. “Generic + Optimized”
– User experience comes first; optimized solutions also drive down cost
2. “Leverage what’s there” and “Any device, anywhere”
– Automatically leverage user device and server capabilities 3. “Dynamically adapt”
– Self‐tune to the network

Delivering Graphics, Video & Unified Communications with HDX
• HDX optimizations for Microsoft Lync, Cisco Unified Communications Manager and Avaya one‐X
• Universal Print Server
• HDX‐Ready System‐on‐Chip thin clients
• HDX 3D Pro • HDX enhancements in new versions of Citrix Receiver
side 4
HDX Technology Overview
side 5
•
Technology to orchestrate all of the other HDX technologies, and enhance virtual application and desktop performance.
Evaluates the resources on the end user’s client device running Citrix Receiver, bandwidth available on the network connection, server resources, key application and desktop characteristics to determine the best delivery method for a high definition user experience. •
•
•
•
Available in both XenApp and XenDesktop
Optimizes the delivery of multimedia content
Using server‐side rendering or client‐side rendering (multimedia redirection)
Flash Redirection (Flash version 2) and Windows Media Redirection. •
side 6
•
•
•
•
•
Technology provides an optimal end user experience with real‐time audio and video
For XenDesktop, HDX RealTime is able to utilize Real‐time Transport Protocol (RTP) built on UDP
Still utilizing the more reliable TCP protocol for the virtual desktop delivery
UDP/RTP is well suited for delivering audio over congested or wireless networks
Ability to utilize the client’s real‐time resources (such as web camera, microphone, and speakers)
•
Technology leverages the ICA and RDP protocols to deliver virtualized applications to any device over any network connection
By using Session reliability, Queuing and Tossing, mouse click feedback and more
•
side 7
•
•
•
•
•
•
Technology that simplifies access to virtualized desktops, applications, and other resources through various Citrix products
Citrix Netscaler Access Gateway provides secure remote and internal access to applications and desktops while supporting the Multi‐Stream ICA and RealTime RTP/UDP technology previously discussed
Through Citrix Open Cloud Gateway, SmartAccess technology can also provide single sign‐on for applications supporting the SAML protocol
Supports the ability to recognize and enumerate peripheral devices within a virtual application and desktop. Supports peripheral devices such as USB devices, printers, scanners, multiple monitors, smart card devices, and more
Provide end users with a peripheral device experience that is on par with applications running on a local desktop
side 8
•
•
Primarily supported by Citrix Branch Repeater which is available as both a physical and virtual appliance
With the XenDesktop 5.5 and XenApp 6.5 release, Citrix unveiled the new Multi‐Stream technology which allows for the individual virtual channels within the HDX (ICA) protocol to be assigned to individual ports for Quality of Service (QoS) network traffic prioritization across a WAN connection

•
•
Group of XenApp and XenDesktop features designed to enhance the graphic performance within a virtualized desktop or application
The individual features address different graphic requirements of both desktops and applications
Aero Redirection provides XenDesktop virtual desktops with Windows 7 Aero Glass themes and features, such as Aero Shake, Flip 3D, and Peek, over a LAN connection by leveraging the GPU or IGP (Integrated Graphics Processor) for rasterizing the Aero commands sent to Citrix Receiver running on the client via the ICA protocol
GDI+ Remoting is included in both XenApp and XenDesktop
Adaptive Orchestration determines whether to send GDI/GDI+ graphics commands to the user device for local rendering by the Citrix Receiver, or to render the graphics on the server and send compressed bitmaps over the wire
HDX 3D is the HDX RichGraphics technology used to deliver DirectX‐based applications
HDX 3D allows multiple XenApp sessions to share a single GPU for DirectX graphics acceleration
HDX 3D Pro can accelerate both DirectX and OpenGL applications inside a virtual desktop
