Quality of Service (QoS)
Video conferencing system is subject to the bandwidth and the delay. Therefore, the QoS is very important for the
network having limited bandwidth. QoS is a major issue in VoIP implementations, regarding how to guarantee that
packet traffic is not delayed or dropped due to interference from other lower priority traffic. Your system supports the
DiffServ model of QoS.
Audio QoS
The loss of audio packets, the delay and so on may cause poor audio quality. To solve this, you can configure DSCP
priority for the audio packets.
Video QoS
Some issues, such as the video packet loss and delay may cause the video images distorted and unclear. To ensure
acceptable visual quality for video, video packets emanated from the system should be configured with a high
transmission priority.
