Setting Description
Configure the maximum
PCoIP session
bandwidth
Specifies the maximum bandwidth, in kilobits per second, in a PCoIP session. The
bandwidth includes all imaging, audio, virtual channel, USB, and control PCoIP traffic.
Set this value to the overall capacity of the link to which your endpoint is connected, taking
into consideration the number of expected concurrent PCoIP sessions. For example, with a
single-user VDI configuration (a single PCoIP session) that connects through a 4Mbit/s
Internet connection, set this value to 4Mbit, or 10% less than this value to leave some
allowance for other network traffic. When you expect multiple concurrent PCoIP sessions to
share a link, comprising either multiple VDI users or an RDS configuration, you might want
to adjust the setting accordingly. However, lowering this value will restrict the maximum
bandwidth for each active session.
Setting this value prevents the agent from attempting to transmit at a higher rate than the
link capacity, which would cause excessive packet loss and a poorer user experience. This
value is symmetric. It forces the client and agent to use the lower of the two values that are
set on the client and agent side. For example, setting a 4Mbit/s maximum bandwidth forces
the agent to transmit at a lower rate, even though the setting is configured on the client.
When this setting is disabled or not configured on an endpoint, the endpoint imposes no
bandwidth constraints. When this setting is configured, the setting is used as the endpoint's
maximum bandwidth constraint in kilobits per second.
The default value when this setting is not configured is 900000 kilobits per second.
This setting applies to the agent and the client. If the two endpoints have different settings,
the lower value is used.
Configure the PCoIP
transport header
Configures the PCoIP transport header and sets the transport session priority.
The PCoIP transport header is a 32-bit header that is added to all PCoIP UDP packets (only
if the transport header is enabled and supported by both sides). The PCoIP transport header
allows network devices to make better prioritization/QoS decisions when dealing with
network congestion. The transport header is enabled by default.
The transport session priority determines the PCoIP session priority reported in the PCoIP
transport header. Network devices make better prioritization/QoS decisions based on the
specified transport session priority.
When the Configure the PCoIP transport header setting is enabled, the following
transport session priorities are available:
n
High
n
Medium (default value)
n
Low
n
Undefined
The transport session priority value is negotiated by the PCoIP agent and client. If the PCoIP
agent specifies a transport session priority value, the session uses the agent-specified session
priority. If only the client has specified a transport session priority, the session uses the
client-specified session priority. If neither agent nor client has specified a transport session
priority, or Undefined Priority is specified, the session uses the default value, Medium
priority.
Enable/disable audio
in the PCoIP session
Determines whether audio is enabled in PCoIP sessions. Both endpoints must have audio
enabled. When this setting is enabled, PCoIP audio is allowed. When it is disabled, PCoIP
audio is disabled. When this setting is not configured, audio is enabled by default.
