PCoIP Bandwidth Settings
The View PCoIP ADM template file contains group policy settings that configure PCoIP bandwidth
characteristics.
Table 17‑9. View PCoIP Session Bandwidth Variables
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 Horizon Agent and the client. If the two
endpoints have different settings, the lower value is used.
Configure the PCoIP session bandwidth
floor
Specifies a lower limit, in kilobits per second, for the bandwidth that is
reserved by the PCoIP session.
This setting configures the minimum expected bandwidth transmission
rate for the endpoint. When you use this setting to reserve bandwidth
for an endpoint, the user does not have to wait for bandwidth to become
available, which improves session responsiveness.
Make sure that you do not over-subscribe the total reserved bandwidth
for all endpoints. Make sure that the sum of bandwidth floors for all
connections in your configuration does not exceed the network
capability.
The default value is 0, which means that no minimum bandwidth is
reserved. When this setting is disabled or not configured, no minimum
bandwidth is reserved.
This setting applies to Horizon Agent and the client, but the setting only
affects the endpoint on which it is configured.
When this setting is modified during an active PCoIP session, the
change takes effect immediately.
