This object configures the maximum Cell Delay Variation (CDV) threshold in microseconds for a path in ATM networks, controlling quality-of-service metrics on a per-connection basis. Cell Delay Variation measures jitter, or the variability in the time between consecutive cells arriving at their destination, which affects real-time traffic quality. Network administrators use this to enforce maximum acceptable jitter limits for voice, video, or other delay-sensitive services across individual virtual circuits.
