Technical Summary
When a packet is sent from one host to the other, one normally
expects that exactly one copy of the packet that was sent arrives
at the destination. It is, however, possible that a packet is
either lost or that multiple copies arrive. This document defines
a metric for the case where a packet is sent, but multiple copies
arrive. The document also discusses streams and methods to
summarize the results of streams.
Working Group Summary
This document was suggested when creating a succint summary of IPPM
metrics for reporting to users; this was one that was missing from the
IPPM metric suite. There is consensus that this is the right
definition.
There has been some question as to whether the definition is crisp and
unambiguous for both IPv4 and IPv6, and the document has been modified
to address those concerns.
Document Quality
The shepherd knows of no current implementations that claim to
implement this
metric. However, vendors in the working group have read and agreed with
the
specification.
Personnel
