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 Matt Zekauskas (email@example.com) was the Document Shepherd. Lars Eggert (firstname.lastname@example.org) reviewed the document for the IESG.
