Summary of Comparisons Challenging Circumstances for measurement: IPDV form offers advantages when Path changes are very Frequent and lossy Meas. System Clocks exhibit “some” Skew PDV form is less sensitive to Packet Loss Spatial Composition of DV metric: All validated methods use PDV, IPDV sensitivities to sequence and spacing changes is an issue, and tend to break the IID requirement. Estimate of Queuing Time & Variation: PDV estimates this, especially when sample min = true min Determine De-jitter Buffer Size Required PDV “pseudo-range” reveals this property by anchoring the distribution at the minimum delay Specification Simplicity (SLA or SLS) one constraint for PDV single-sided positive distribution |
