Configuring Quality of Service (QOS)
If your network is configured to recognize and prioritize network traffic using
QOS, you can configure the V500 system to mark IP packets with the values
recognized by your network. Keep in mind that enabling QOS on the V500 is not
enough; all devices in the network path must also be configured for QOS.
If you are unfamiliar with QOS, Polycom recommends that you do not change the
default settings.
To configure the Quality of Service (QOS) options:
1.
Go to
System > Admin Settings > Network >
IP > Quality of Service
.
2.
Configure these settings:
Setting
Description
Type of Service
Select your service type:
•
IP Precedence — Lets you specify the priority of IP packets
sent to the system. The value, which you enter in the Type of
Service Value field, can be between 0 and 5.
•
DiffServ —Lets you specify a priority level between 0 and 63.
Enter the value in the Type of Service Value field.
Type of Service
Value
Specify the IP Precedence or Diffserv value for Video, Audio, and
Far-Site Camera Control.
Enable PVEC
Check this if you want the system to use PVEC (Polycom Video
Error Concealment) if packet loss occurs.
Dynamic
Bandwidth
Check this if you want the V500 system to dynamically scale the
bandwidth to best suit the network conditions.
Maximum Transmit
Bandwidth
Specify the maximum transmit line speed between 48 Kbps and
512 Kbps.
Since DSL and cable modems typically allow for faster download
(receive) speeds compared to upload (transmit) speeds, this
setting enables you to regulate differences.
Maximum Receive
Bandwidth
Specify the maximum receive line speed between 48 Kbps and
512 Kbps.
