This memo defines a Media Delivery Index (MDI) measurement that can be
used as a diagnostic tool or a quality indicator for monitoring a
network intended to deliver applications such as streaming media, MPEG
video, Voice over IP, or other information sensitive to arrival time
and packet loss.  It provides an indication of traffic jitter, a
measure of deviation from nominal flow rates, and a data loss
at-a-glance measure for a particular flow.  For instance, the MDI
may be used as a reference in characterizing and comparing networks
carrying UDP streaming media.  This memo provides information for the Internet community.
