Title : Reorder Density and Reorder Buffer-occupancy Density - Metrics for Packet Reordering Measurements
Author(s) : A. Jayasumana, et al.
Filename : draft-jayasumana-reorder-density-08.txt
Pages : 23

This document presents two 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.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
