	Title		: Packet Reordering Metric for IPPM

This memo defines metrics to evaluate if a network has maintained 
   packet order on a packet-by-packet basis. It provides motivations 
   for the new metrics and discusses the measurement issues, including 
   the context information required for all metrics. The memo first 
   defines a reordered singleton, and then uses it as the basis for 
   sample metrics to quantify the extent of reordering in several 
   useful dimensions for network characterization or receiver design. 
   Additional metrics quantify the frequency of reordering and the 
   distance between separate occurrences. We then define a metric 
   oriented toward assessing reordering effects on TCP. Several 
   examples of evaluation using the various sample metrics are 
   included. An Appendix gives extended definitions for evaluating 
   order with packet fragmentation.

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
