Reporting IP Network Performance Metrics: Different Points of View
Abstract
Consumers of IP network performance metrics have many different uses
in mind. This memo provides "long-term" reporting considerations
(e.g., hours, days, weeks, or months, as opposed to 10 seconds),
based on analysis of the points of view of two key audiences. It
describes how these audience categories affect the selection of
metric parameters and options when seeking information that serves
their needs.
Status of This Memo
This document is not an Internet Standards Track specification; it is
published for informational purposes.
This document is a product of the Internet Engineering Task Force
(IETF). It represents the consensus of the IETF community. It has
received public review and has been approved for publication by the
Internet Engineering Steering Group (IESG). Not all documents
approved by the IESG are a candidate for any level of Internet
Standard; see Section 2 of RFC 5741.
