WAN Support and PCoIP
For wide-area networks (WANs), you must consider bandwidth constraints and latency issues. The PCoIP
display protocol provided by VMware adapts to varying latency and bandwidth conditions.
If you use the RDP display protocol, you must have a WAN optimization product to accelerate applications
for users in branch offices or small offices. With PCoIP, many WAN optimization techniques are built into
the base protocol.
n
WAN optimization is valuable for TCP-based protocols such as RDP because these protocols require
many handshakes between client and server. The latency of these handshakes can be quite large. WAN
accelerators spoof replies to handshakes so that the latency of the network is hidden from the protocol.
Because PCoIP is UDP-based, this form of WAN acceleration is unnecessary.
n
WAN accelerators also compress network traffic between client and server, but this compression is
usually limited to 2:1 compression ratios. PCoIP is able to provide compression ratios of up to 100:1 for
images and audio.
For information about the controls introduced with View 5 that you can use to adjust the way PCoIP
consumes bandwidth, see “Optimization Controls Available with PCoIP,” on page 63.
Bandwidth Requirements for Various Types of Users
When determining minimum bandwidth requirements for PCoIP, plan with the following estimates:
n
100 to 150Kbps average bandwidth for a basic office productivity desktop: typical office applications
with no video, no 3D graphics, and the default Windows and View settings.
n
50 to 100Kbps average bandwidth for an optimized office productivity desktop: typical office
applications with no video, no 3D graphics, with Windows desktop settings optimized and View
optimized.
n
400 to 600Kbps average bandwidth for virtual desktops utilizing multiple monitors, 3D, Aero, and
Office 2010.
n
500Kbps to 1Mbps minimum peak bandwidth to provide headroom for bursts of display changes. In
general, size your network using the average bandwidth, but consider peak bandwidth to
accommodate bursts of imaging traffic associated with large screen changes.
n
2Mbps per simultaneous user running 480p video, depending upon the configured frame rate limit and
the video type.
NOTE The estimate of 50 to 150Kbps per typical user is based on the assumption that all users are operating
continuously and performing similar tasks over an 8- to 10- hour day. The 50Kbps bandwidth usage figure
is from View Planner testing on a LAN with the Build-to-Lossless feature disabled. Situations may vary in
that some users may be fairly inactive and consume almost no bandwidth, allowing more users per link.
Therefore, these guidelines are intended to provide a starting point for more detailed bandwidth planning
and testing.
The following example shows how to calculate the number of concurrent users at a branch or remote office
that has a 1.5Mbps T1 line.
Branch or Remote Office Scenario
n
Users have basic Microsoft Office productivity applications, no video, no 3D graphics, and USB
keyboards and mouse devices.
n
The bandwidth required per typical office user on View is from 50-150Kbps.
n
The T1 network capacity is 1.5Mbps.
