Table 5‑10. Horizon PCoIP Session Bandwidth Variables (Continued)
Setting Description
Configure the PCoIP session MTU
Species 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 aected by
this seing.
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 seing applies to Horizon Agent and the client. If the two
endpoints have dierent MTU size seings, the lowest size is used.
If this seing is disabled or not congured, the client uses the default
value in the negotiation with Horizon Agent.
Configure the PCoIP session audio
bandwidth limit
Species the maximum bandwidth that can be used for audio (sound
playback) in a PCoIP session.
The audio processing monitors the bandwidth used for audio. The
processing selects the audio compression algorithm that provides the
best audio possible, given the current bandwidth utilization. If a
bandwidth limit is set, the processing reduces quality by changing the
compression algorithm selection until the bandwidth limit is reached. If
minimum quality audio cannot be provided within the bandwidth limit
specied, audio is disabled.
To allow for uncompressed high quality stereo audio, set this value to
higher than 1600 kbit/s. A value of 450 kbit/s and higher allows for
stereo, high-quality, compressed audio. A value between 50 kbit/s and
450 kbit/s results in audio that ranges between FM radio and phone call
quality. A value below 50 kbit/s might result in no audio playback.
This seing applies to Horizon Agent only. You must enable audio on
both endpoints before this seing has any eect.
In addition, this seing has no eect on USB audio.
If this seing is disabled or not congured, a default audio bandwidth
limit of 500 kilobits per second is congured to constrain the audio
compression algorithm selected. If the seing is congured, the value is
measured in kilobits per second, with a default audio bandwidth limit
of 500 kilobits per second.
This seing applies to View 4.6 and later. It has no eect on earlier
versions of View.
When this seing is modied during an active PCoIP session, the
change takes eect immediately.
Turn off Build-to-Lossless feature
Species whether to turn the build-to-lossless feature of the PCoIP
protocol o or on. This feature is turned o by default.
If this seing is enabled or not congured, the build-to-lossless feature is
turned o, and images and other desktop and application content are
never built to a lossless state. In network environments with constrained
bandwidth, turning o the build-to-lossless feature can provide
bandwidth savings.
If this seing is disabled, the build-to-lossless feature is turned on.
Turning on the build-to-lossless feature is recommended in
environments that require images and other desktop and application
content to be built to a lossless state.
When this seing is modied during an active PCoIP session, the
change takes eect immediately.
