This document specifies new IP Flow Information Export (IPFIX)
Information Elements to export the On-Path delay at each Operations,
Administration, and Maintenance (OAM) transit and decapsulating
nodes. The On-Path delay is defined as the delay between the OAM
header encapsulating node and each OAM header transit and OAM header
decapsulating nodes. This delay measurement is computed by an On-Path
Telemetry protocol and is exported by the IPFIX process.

This document is a product of the Operations and Management Area Working Group Working Group of the IETF.

This is now a Proposed Standard.
