5 Separate the physical endpoint from the logical desktop Host the logical desktop in a data center Allow endpoints to access the logical desktop over the network Endpoints may include a variety of device types; end user continues where he/she last left off Virtualized desktop hosted in DC 5

6 In principle, the business case is compelling. Desktop virtualization helps companies: Improved manageability Streamlined deployment Increased flexibility Connection Broker Improved data protection Better resource utilization Reduced costs Hypervisor 6

10 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 10

11 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, clients and office automation tools, but also additional features such as streaming audio and video 11

12 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 12

16 Quality of user experience Rich media streaming, voice/video, remote access often less than optimal Performance: Voice/Video cannot be prioritized by QoS Jitter: Voice traffic must go round trip Bandwidth: Each new copy streamed for each additional DV client = branch WAN bandwidth overruns Display Protocol Virtualized Virtualization Aware Collaboration Workplace Network Virtualized Data Center Current display protocols are opaque to network services The key to applying services is to separate the flows 16

17 Video Source Video processed on HVD causing bandwidth and server compute overload Branch Office End-users see pixelization as media is rendered from the data center Branch Router E1 Increasing bandwidth might not help Data Center Campus End-users experience no pixelization on LAN 17

18 Branch Office Video Source Branch Router E1 Routing Protocol Data Center Protocols in the virtual desktop environment appear monochrome to QoS Lack of flow differentiation prevents prioritization within a display protocol stream Video Display Protocol Video stream competes with other flows in class (e.g.: CIFS, SAMBA or NFS, ) 18

19 Hairpin Effect causing undesirable results Data Center Virtual Desktop Signalling (SIP) CUCM Signalling (SIP) Display Protocol Media Flow WAN Thin Client 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 Bandwidth explosion Display protocol and possible endpoint become unstable Virtual Desktop Media Flow Display Protocol Thin Client 19
