Purpose: For information

Body: There is increasing interest across the industry in better understanding, measuring, and managing latency
and other quality metrics, for example, the September 2021 IAB workshop on Measuring Network Quality for
End Users (RFC 9318). We have previously noted that the Broadband Forum has an ongoing program of
work called “Quality Experience Delivered” relating to this within the Performance, Experience, and
Application Testing (PEAT) project stream. This program has previously produced a specification TR-452.1,
entitled “Quality Attenuation Measurement Architecture and Requirements”, which can be accessed here:
https://www.broadband-forum.org/technical/download/TR-452.1.pdf. This specification details the overall
approach, a generic approach to measurement of latency and its decomposition into meaningful
components, and a number of use-cases.

A recent strand of work has concluded with the publication of a new specification TR-452.2, entitled “Quality
Attenuation Measurements using Active Test Protocols” which can be accessed here:
https://www.broadband-forum.org/technical/download/TR-452.2.pdf. This allows the approach to be applied
much more widely at low cost by leveraging existing protocol capabilities (for example in CPE devices) such
as TWAMP or STAMP. This opens up new use-cases beyond network design and lab evaluation such as
pro-active sampling of network performance and support for customer service troubleshooting.

For further information contact [e-mail].

Sincerely,
Lincoln Lavoie
Broadband Forum Technical Committee Chair
