Reorder Density (RD): A Formal, Comprehensive Metric for Packet Reordering
... IP telephony, an out-of-order packet that arrives after the elapse of playback time is treated as lost thereby decreasing the perceived quality of voice. To recover from reordering, the out-of-sequence packets are buffered until they can be played back in sequence to the application. Thus, an increa ...
