Technical Summary
The IETF has standardized IP Performance Metrics (IPPM) for measuring
end-to-end performance between two points.  This memo defines two new
categories of metrics that extend the coverage to multiple
measurement points.  It defines spatial metrics for measuring the
performance of segments of a source to destination path, and metrics
for measuring the performance between a source and many destinations
in multiparty communications (e.g., a multicast tree).

Working Group Summary
The working group input has improved this document through its
revisions, and the document itself has been uncontroversial.
Document Quality
No known implementations claim to implement this metric.
However, other implementers in the group have read the draft.
