          IP Performance Metrics (IPPM): Spatial and Multicast

Abstract

   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).

Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.
