Table 5‑13. Horizon 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.
