View PCoIP Session Bandwidth Variables
The View PCoIP Session Variables ADM template file contains group policy settings that configure PCoIP
session bandwidth characteristics.
Table 8-35. 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. For example, for a client that connects through a 4Mbit/s
Internet connection, set this value to 4Mbit, or 10% less than this value.
Setting this value prevents the server 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 server to use the lower of the two values that are set on the client and
server side. For example, setting a 4Mbit/s maximum bandwidth forces
the server 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 90000 kilobits per
second.
This setting applies to View 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 View Agent and the client, but the setting only
affects the endpoint on which it is configured.
Configure the PCoIP session MTU
Specifies the Maximum Transmission Unit (MTU) size for UDP packets
for a PCoIP session.
The MTU size includes IP and UDP packet headers. TCP uses the standard
MTU discovery mechanism to set MTU and is not affected by this setting.
The maximum MTU size is 1500 bytes. The minimum MTU size is 500
bytes. The default value is 1300 bytes.
Typically, you do not have to change the MTU size. Change this value if
you have an unusual network setup that causes PCoIP packet
fragmentation.
This setting applies to View Agent and the client. If the two endpoints have
different MTU size settings, the lowest size is used.
If this setting is disabled or not configured, the client uses the default value
in the negotiation with View Agent.
