  "The worldwide hosted virtual desktop (HVD) market will accelerate through 2013 to reach 49 million units, up from more than 500,000 units in 2009, according to Gartner Inc.

  Worldwide HVD revenue will grow from about $1.3 billion to $1.5 billion in 2009, which is less than 1 percent of the worldwide professional PC market, to $65.7 billion in 2013, which will be equal to more than 40 percent of the worldwide professional PC market.”

Desktop Virtualization Challenges

Return on Investment


  Protocols in the virtual desktop environment appear “monochrome” to QoS

  Lack of flow differentiation prevents prioritization within a display protocol stream

  Video stream competes with other flows in class – (e.g.: CIFS, SAMBA or NFS, )

•  Monolithic data flows •  Voice/Video in the display protocol Media

flow goes all the way back to data center and back

•  Heavy processing on virtual desktop in data center

  Zero clients are the simplest devices

  They have embedded operating systems that are not exposed to the user

  Zero clients have reduced local capabilities and depend heavily on the resources available within the virtual desktop

  This class of devices is typically slated toward the task worker since it provides no enhancements for media streaming

  Because there is no exposed OS, there is no virus infection, making them a very secure endpoint


  Introducing the Cisco VXC 2100 and 2200 Support for PCoIP and ICA/RDP display protocols Cisco VXC 2100 is a compact device that integrates with the Cisco Unified IP Phone 8961 and 9900 Cisco VXC 2200 is a standalone unit Both units support PoE (Power over Ethernet)

Cisco VXC 2200 Cisco VXC 2100


 VXC endpoints don’t have native telephony capabilities today.   Hardphone control is used to integrate telephony: Example: in a video call the video will not be displayed on the monitor connected to VXC

 VXI specific feature support   MMR : Supported in VXC 2x12 (Citrix) – RDP only   Smartcard : Supported in VXC 2x12 (Citrix)   USB Redirection: Supported on all VXC endpoints   Native Dot1x: Supported in VXC 2x12 (Citrix) only. Dot1x supplicants can’t be installed separately on any VXC

 VXC 2x11 (VMware) supports PCoIP in hardware using Terradici chipset

 Virtual Experience Client Manager (VXC Manager) can be used for enforcing peripheral policies, pushing configurations (DHCP etc) and firmware upgrades.

  Thin client devices usually contain more local capabilities and often have a customizable local embedded operating system (usually Linux or Windows)

  This class of endpoint provides greater flexibility

  They are generally customized by the system administrators and then locked down

  Thin clients are typically used by power users who need access not only to browsers, email clients and office automation tools, but also additional features such as streaming audio and video


  CIUS supports simultaneous voice/video telephony and desktop virtualization – Integrated Cisco Softphone

  Supports external display in “mirror mode” – Users can’t see phone control and virtual desktop at the same time

  Base supports POE (Requires 30 W)

Software Thick Desktop Display Protocol Clients

  Thick client devices refer to standard PC or Laptops running a standard OS but have similar software as the thin client installed as an application

  Thick client devices allow users to work offline and are often the choice of the “Road Warrior” user

End-users see pixelization as media is rendered from the data center


  Watching Video with RDP is unacceptable without WAAS, due to bandwidth explosion. WAAS provides 91% compression ratio

  There is no benefit to WAN Optimization with PCoIP PCoIP is an encrypted protocol over UDP

  WAAS improves Citrix ICA “XenDesktop 4.0” with a compression ratio of 55%


  When an endpoint sends a document to a printer, the request actually takes place within the data center where the virtual desktop and print server are located

  The print data going to the network printer travels outside the desktop display protocol and can be optimized with WAAS
