Chapter 3 - Configuring Network Use
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 |
| Enter the value in the Type of Service Value field. |
|
|
Type of Service | Specify the IP Precedence or Diffserv value for Video, Audio, and |
Value | |
|
|
Enable PVEC | Check this if you want the system to use PVEC (Polycom Video |
| Error Concealment) if packet loss occurs. |
|
|
Dynamic | Check this if you want the V500 system to dynamically scale the |
Bandwidth | bandwidth to best suit the network conditions. |
|
|
Maximum Transmit | Specify the maximum transmit line speed between 48 Kbps and |
Bandwidth | 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 | Specify the maximum receive line speed between 48 Kbps and |
Bandwidth | 512 Kbps. |
