PCoIP Zero Client and Host Administrator Guide (Issue 5)

Parameter Description
Device Bandwidth Floor Enter the minimum bandwidth when congestion is present and
bandwidth is required. This allows you to optimize performance for a
network with understood congestion or packet loss. If the bandwidth
is not required, the bandwidth used drops below the floor.
When configuring hosts, this setting defines the minimum bandwidth
from the host to the client (e.g., graphics data).When configuring
clients, it defines the minimum bandwidth from the client to the host
(e.g., USB data).
A setting of 0 configures the PCoIP processor to reduce bandwidth to
1000 Kbps during these network impairments. You should have a
good understanding of the network topology before setting this to a
non-zero value.
Note: The firmware implements a slow-start algorithm that increases
the bandwidth used until the required bandwidth is reached, network
congestion is detected, or the Device Bandwidth Limit is met. It
begins at the lesser of the Device Bandwidth Limit and 8000 Kbps,
and increases the bandwidth used within seconds. The slow-start
algorithm allows a graceful session startup for low bandwidth
scenarios (e.g., WAN scenarios). After initiating a PCoIP session,
users may temporarily notice low bandwidth video artifacts as the
algorithm ramps up bandwidth use.
Note: When applied to devices running firmware older than 3.0, a
value other than 0 is rounded to the nearest Megabit per second,
with a minimum value of 1 Mbps.
7.9.2 AWI: Bandwidth Settings
The settings on this page let you control the bandwidth used by a host or client during a
PCoIP session. You can display this page for a host or client from the Configuration >
Bandwidth menu. The parameters on this page are applied immediately after you click
Apply.
