Abstract
This memo describes an extension to the TWAMP test protocol for
identifying and managing packet trains, which enables measuring
capacity metrics like the available path capacity, tight section
capacity and UDP delivery rate in the forward and reverse path
directions.
This memo contains the description of a working prototype. It does
not represent a consensus of the IETF community. The IETF community
is currently working on the problem statement and has not reached
consensus on the preferred method for measuring capacity metrics.
Status of this Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at http://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months

1 Introduction
The notion of embedding a number of meaningful fields in the padding
octets has been established as a viable methodology for carrying
additional information within the TWAMP-Test protocol running between
a Session-Sender and a Session-Reflector [RFC5357] [RFC6038].
This memo describes an optional extension to the Two-Way Active
