1. Summary
The document shepherd is Tal Mizrahi, and the responsible area director is
Mirja Kühlewind.
This document describes a Simple Two-way Active Measurement Protocol (STAMP),
which enables the measurement of both one-way and round-trip performance
metrics like delay, delay variation, and packet loss.
The intended status of this document is Standards Track, as it defines a
protocol variant that continues the evolution of the Two-Way Active Measurement
Protocol (TWAMP).
The IPPM working group is also working on a companion draft,
draft-ietf-ippm-stamp-yang, which defines a YANG data model for STAMP. This
companion draft will be sent to the IESG for publication in the future.
2. Review and Consensus
The draft was first submitted in October 2017, has been reviewed by a fair
number of people in the IPPM working group, has had a fair number of
supporters, and no objections from the working group.
One of the main issues that was discussed in the context of this draft is the
security considerations. The IPPM minutes from IETF 103 summarize this
discussion
(https://datatracker.ietf.org/meeting/103/materials/minutes-103-ippm-00). Two
main questions were raised: one regarding the size of the integrity protection
HMAC, and the other regarding whether encryption is required for STAMP or not.
Arguments were made both ways. After IETF 103 the authors proposed the solution
that is in the current draft with no objections from the working group:
regarding the first issue, the HMAC is based on a SHA-256 truncated to 128
bits, and regarding the second issue, the draft does not define an encryption
mechanism, but states that encryption may be provided at higher layers.
Several other comments that have been raised on the mailing list have been
addressed by the editors.
The current version of the draft is clear, seems to have resolved all the
issues, and has the consensus of the working group.
