This document presents two improved metrics for packet reordering,
namely, Reorder Density (RD) and Reorder Buffer-occupancy Density
(RBD). A threshold is used to clearly define when a packet is
considered lost, to bound computational complexity at O(N), and to
keep the memory requirement for evaluation independent of N, where N
is the length of the packet sequence. RD is a comprehensive metric
that captures the characteristics of reordering, while RBD evaluates
the sequences from the point of view of recovery from reordering.
These metrics are simple to compute yet comprehensive in their
characterization of packet reordering. The measures are robust and
orthogonal to packet loss and duplication. This memo provides
