Setting Description
Configure PCoIP image quality levels
Controls how PCoIP renders images during periods of network
congestion. The Minimum Image Quality, Maximum Initial Image
Quality, and Maximum Frame Rate values interoperate to provide fine
control in network-bandwidth constrained environments.
Use the Minimum Image Quality value to balance image quality and
frame rate for limited-bandwidth scenarios. You can specify a value
between 30 and 100. The default value is 50. A lower value allows higher
frame-rates, but with a potentially lower quality display. A higher value
provides higher image quality, but with potentially lower frame rates
when
network bandwidth is constrained. When network bandwidth is not
constrained, PCoIP maintains maximum quality regardless of this value.
Use the Maximum Initial Image Quality value to reduce the network
bandwidth peaks required by PCoIP by limiting the initial quality of the
changed regions of the display image. You can specify a value between 30
and 100. The default value is 90. A lower value reduces the image quality
of content changes and decreases peak bandwidth requirements. A higher
value increases the image quality of content changes and increases peak
bandwidth requirements. Unchanged regions of the image progressively
build to a lossless (perfect) quality regardless of this value. A value of 90
or lower best utilizes the available bandwidth.
The Minimum Image Quality value cannot exceed theMaximum Initial
Image Quality value.
Use the Maximum Frame Rate value to manage the average bandwidth
consumed per user by limiting the number of screen updates per second.
You can specify a value between 1 and 120 frames per second. The default
value is 30. A higher value can use more bandwidth but provides less jitter,
which allows smoother transitions in changing images such as video. A
lower value uses less bandwidth but results in more jitter.
These image quality values apply to the soft host only and have no effect
on a soft client.
When this setting is disabled or not configured, the default values are used.
Configure PCoIP session encryption
algorithms
Controls the encryption algorithms advertised by the PCoIP endpoint
during session negotiation.
Checking one of the check boxes disables the associated encryption
algorithm. You must enable at least one algorithm.
By default, both the Salsa20-256round12 and AES-128-GCM algorithms
are available for negotiation by this endpoint.
This setting applies to both server and client. The endpoints negotiate the
actual session encryption algorithm that is used. If FIPS140-2 approved
mode is enabled, the Disable AES-128-GCM encryption value is always
overridden so that AES-128-GCM encryption is enabled.
If this setting is disabled or not configured, both the Salsa20-256round12
and AES-128-GCM algorithms are available for negotiation by this
endpoint.
