Quality of service (QoS) involves classifying and prioritizing network packets to guarantee performance for critical applications. Network administrators configure QoS rules on routers and switches to reserve bandwidth and reduce latency for real-time traffic like voice or video. Without these policies, a large file transfer could easily cause dropped frames or choppy audio during a conference call.
We need to adjust the QoS policies on the edge router because the VoIP phones are dropping packets when the backup job runs.
