	Title		: Spatial metrics for IPPM

The IETF IP Performance Metrics (IPPM) working group has standardized 
metrics for measuring end-to-end performance. This memo defines 
spatial metrics both for measuring end-to-end network performance 
using aggregation of sequence of network measures and for measuring 
the performance of segments of an IP path trajectory. It 
distinguishes clearly the decomposition of one end-to-end measure 
result in a sequence of per hop results from the aggregation of a 
sequence of per hop measure results in an end-to-end result.

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.
