This document defines an optional extension to the Simple Two-way Active 
Measurement Protocol (STAMP) that enables a Session-Reflector to send 
asymmetrical packets, that is, response packets whose size or quantity differs 
from those sent by the Session-Sender. While standard STAMP exchanges are 
symmetrical, certain measurement scenarios benefit from reflected packets of 
different lengths or additional responses to better approximate application 
traffic conditions. The extension specifies the Reflected Test Packet Control 
TLV and associated procedures, analyzes challenges in active performance 
measurement (including in multicast environments), and describes STAMP 
behaviors to improve measurement efficiency and reduce network impact.

This document is a product of the IP Performance Measurement Working Group of 
the IETF.

STANDARDS TRACK: This document specifies an Internet Standards Track
