To ensure high quality communication in video conferencing, the TrueConf client application for Windows<\/a> requires high-priority access to network resources. In the case when the internet channel is idle and not busy, this is usually not a problem. But if it is used intensively (e.g. when downloading files from several resources simultaneously) video and audio freezes, low picture quality or periodic connection interruptions can be present in meetings.
\n<\/p>\n

You can improve the quality of video calls and conferences by using QoS traffic prioritization technology<\/a>. The principle of its operation is quite simple: incoming and outgoing application traffic, which requires low latency and guaranteed bandwidth, is marked as priority and will be processed by the router in the first place.<\/p>\n

You can read more about the technical implementation of QoS here<\/a>.<\/div>\n

This article describes how to set up QoS step by step.<\/p>\n

How to enable the qWave component for servers running the Windows Server OS<\/h2>\n

In order to take advantage of packet classification, you need to have this feature enabled on the server where TrueConf Server is deployed. To do this, install the qWave network platform:<\/p>\n

    \n
  1. Start Server Manager<\/strong>.<\/li>\n
  2. Select Add roles and features<\/strong>.
    \n    \"\"<\/a><\/li>\n
  3. The server and network environment information page will open. Make sure everything is prepared for the component installation and go to the next step.<\/li>\n
  4. Select Role-based or feature-based installation<\/strong>.<\/li>\n
  5. Specify the required server from the list.<\/li>\n
  6. Select the required server roles, if necessary.<\/li>\n
  7. In the list of features, select Quality Windows Audio Video Experience <\/strong>and click Next \u2192 Install<\/strong>.
    \n    \"\"<\/a>
    \nWhen the installation is complete, click Close<\/strong>.<\/li>\n
  8. Reboot the Windows Server for the changes to take effect.<\/li>\n<\/ol>\n
    You can also install qWave from the PowerShell (run as administrator) by entering the command: Add-WindowsFeature<\/code>, then qwave<\/code> and press Enter<\/b> twice.<\/div>\n

    The following default values are used for DSCP marks<\/a> on TrueConf Server:<\/p>\n
