A One-Way Loss Metric for IP Performance Metrics (IPPM)
Abstract
This memo defines a metric for one-way loss of packets across
Internet paths. It builds on notions introduced and discussed in the
IP Performance Metrics (IPPM) Framework document, RFC 2330; the
reader is assumed to be familiar with that document. This memo makes
RFC 2680 obsolete.
Status of This Memo
This is an Internet Standards Track document.
