Table 5‑10. Horizon PCoIP Session Bandwidth Variables
Setting Description
Configure the maximum PCoIP session
bandwidth
Species the maximum bandwidth, in kilobits per second, in a PCoIP
session. The bandwidth includes all imaging, audio, virtual channel,
USB, and control PCoIP trac.
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
conguration (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 trac. When you expect
multiple concurrent PCoIP sessions to share a link, comprising either
multiple VDI users or an RDS conguration, you might want to adjust
the seing accordingly. However, lowering this value will restrict the
maximum bandwidth for each active session.
Seing this value prevents the agent from aempting 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, seing a 4Mbit/s maximum
bandwidth forces the agent to transmit at a lower rate, even though the
seing is congured on the client.
When this seing is disabled or not congured on an endpoint, the
endpoint imposes no bandwidth constraints. When this seing is
congured, the seing is used as the endpoint's maximum bandwidth
constraint in kilobits per second.
The default value when this seing is not congured is 900000 kilobits
per second.
This seing applies to Horizon Agent and the client. If the two
endpoints have dierent seings, the lower value is used.
Configure the PCoIP session bandwidth
floor
Species a lower limit, in kilobits per second, for the bandwidth that is
reserved by the PCoIP session.
This seing congures the minimum expected bandwidth transmission
rate for the endpoint. When you use this seing 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 oors for all
connections in your conguration does not exceed the network
capability.
The default value is 0, which means that no minimum bandwidth is
reserved. When this seing is disabled or not congured, no minimum
bandwidth is reserved.
This seing applies to Horizon Agent and the client, but the seing only
aects the endpoint on which it is congured.
When this seing is modied during an active PCoIP session, the
change takes eect immediately.
