Desktop Virtualization and the Display Protocol
Desktop virtualization aims to reduce the total cost of ownership (TCO) for desktop management,
while providing an equivalent or better end-user experience to what is available with a physical PC.
The VMware® View™ approach to desktop virtualization includes management of virtual machines both
in = the datacenter as well as on local devices through the client virtualization platform.
For desktops hosted in the datacenter, the screen, keyboard, and mouse must be ‘displayed’ to a remote
endpoint. The display protocol performs this function and is one of the primary factors defining the quality of
the end-user experience when users perform functions such as moving application windows, scrolling through
documents and accessing rich media content. IT organizations have historically faced challenges when using
traditional display protocols to try to deliver a full fidelity experience to end-users, therefore reducing the reach
and limiting the possible use cases for desktop virtualization. The introduction of VMware View with PCoIP
delivers a rich user experience over any IP network—thus addressing more use cases and accelerating the
adoption of desktop virtualization solutions.
PCoIP: A Purpose Built Protocol
VMware View with the PCoIP protocol was designed to deliver an uncompromised desktop experience
to a broad set of users with a single protocol over the LAN and WAN. To meet this objective, the protocol
approaches the task of delivering the virtual desktop dierently than other display protocols. The vision from
the beginning was to deliver a rich desktop experience, made up of content such as application windows,
web pages, graphics, text, streaming video, and audio. To deliver on this vision, PCoIP was architected to
recognize dierent types of content and then use dierent compression algorithms based on the content type.
Recognizing that the desktop is a composite of dierent content types resulted in a display protocol ideally
suited to deliver on the promise of a rich user experience. PCoIP delivers a much-improved experience to end-
users accessing virtual desktops across the WAN when compared to legacy display protocols such as RDP.
The graphs below compare PCoIP to RDP and show a more than 50 percent reduction in display latency for the
common operations of manipulating presentations and scrolling through lengthy PDF documents.
