PCoIP Zero Client and Host Administrator Guide (Issue 5)

Note: For details about other resolution options, see PCoIP Host Cards and Zero Clients.
9.4 Host Cards
PCoIP host cards are small add-in cards that can be integrated into tower PCs, rack mount
PCs, PC blades, and server blades. The card's TERA-series processor performs advanced
display compression algorithms to encode a user's full desktop environment. This
information is then communicated in real time over an IP network to the user's PCoIP zero
client.
For complete details about PCoIP host cards, see the Teradici website at

9.5 PCoIP Software Session Variables
The PCoIP software session variables in Microsoft's Group Policy Object (GPO) editor let
you configure users' desktops with a collection of parameters that affect PCoIP sessions
with soft hosts. These variables are defined in a GPO administrative template file called
pcoip.adm, which is located on the VMware View Connection Server installation directory
(\\”servername”\c$\Program Files\VMware\VMware
View\Server\extras\GroupPolicyFiles\pcoip.adm).
You can enable and configure PCoIP software session variables in either the Group Policy
Object editor's PCoIP Session Variables > Overridable Administrator Defaults list to
allow users to override settings or the PCoIP Session Variables > Overridable
Administrator Defaults list to prevent users from overriding settings.
Note: For large environments, you can apply pcoip.adm to a Windows Active Directory
organizational unit (OU) or to a machine that you are configuring as a template for a
desktop pool. For further details, see "VMware View 5 with PCoIP Network Optimization
Guide" from the VMware Documentation website.
For instructions on how to load the PCoIP session variables template to a virtual machine's
GPO editor, please see Knowledge Base support topic 15134-349 on the Teradici support
site. For detailed information on each PCoIP session variable, see support topic 15134-348.
9.6 PCoIP Packet Format
PCoIP is a real-time technology that uses UDP as the transport-layer protocol. PCoIP
supports two encryption types—UDP-encapsulated ESP and native IPsec ESP. An
unencrypted PCoIP transport header field is also present for devices with firmware 4.1.0+
installed and/or for scenarios using View 5.1+. The PCoIP transport header allows network
devices to make better QoS decisions for PCoIP traffic.
Note: TCP/UDP port 4172 is the Internet Assigned Numbers Authority (IANA) port
assigned to the PCoIP protocol. UDP port 4172 is used for the session data, and TCP port
4172 is used for the session handshake. For more information about TCP/UDP ports that are
