Two-Way Active Measurement Protocol (TWAMP) Reflect Octets and
Symmetrical Size Features
Abstract
This memo describes two closely related features for the core
specification of the Two-Way Active Measurement Protocol (TWAMP): an
optional capability where the responding host returns some of the
command octets or padding octets to the sender, and an optional
sender packet format that ensures equal test packet sizes are used in
both directions.
