Internet Engineering Task Force (IETF) A. Morton Request for Comments: 6038 L. Ciavattone Updates: 5357 AT&T Labs Category: Standards Track October 2010 ISSN: 2070-1721 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. Status of This Memo This is an Internet Standards Track document. 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). Further information on Internet Standards is available in Section 2 of RFC 5741.
