This document describes protocol-independent methods called Explicit
Host-to-Network Flow Measurement Techniques that can be applicable to
transport-layer protocols between the client and server. These
methods employ just a few marking bits inside the header of each
packet for performance measurements and require the client and server
to collaborate. Both endpoints cooperate by marking packets and,
possibly, mirroring the markings on the round-trip connection. The
techniques are especially valuable when applied to protocols that
encrypt transport headers since they enable loss and delay
measurements by passive, on-path network devices. This document
describes several methods that can be used separately or jointly
depending of the availability of marking bits, desired measurements,
and properties of the protocol to which the methods are applied.

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