	Title		: Reorder Density Function - Metric for packet 
                          reordering measurement

Out-of-order arrival of packets can significantly degrade the
performance of many TCP-based, VoIP-based and Video-based
applications. There is a need for a metric that can meaningfully,
accurately and unambiguously characterize reordering. This memo
proposes a new metric called Reorder Density function (RD), which can
give an in-depth view of the reordering present in any packet
sequence. This well-defined metric can also be used to evaluate
effects of protocol and hardware implementations on packet
reordering. The memo also provides an algorithm to compute the
reorder density function followed by some illustrative examples.

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.
