Explanation

Real-time applications such as VoIP and video conferencing are extremely sensitive to packet loss. Industry standards and Cisco best practices require that average IP packet loss remain at or below 1% to maintain acceptable audio and video quality. Above 1%, users experience noticeable degradation - clipping, drop-outs, and jitter artifacts. Values above 2% (A) or in the 2–5% range (D) are considered unacceptable for real-time traffic, while 'less than 10%' (C) is far too lenient and would result in poor call quality.
