Alternate-Marking Method for Passive and Hybrid Performance Monitoring
Abstract
This document describes a method to perform packet loss, delay, and
jitter measurements on live traffic. This method is based on an
Alternate-Marking (coloring) technique. A report is provided in
order to explain an example and show the method applicability. This
technology can be applied in various situations, as detailed in this
document, and could be considered Passive or Hybrid depending on the
application.
Status of This Memo
This document is not an Internet Standards Track specification; it is
published for examination, experimental implementation, and
evaluation.
This document defines an Experimental Protocol for the Internet
community. 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 7841.
