Technical Summary
This document aims to enrich DOTS signal channel protocol with
various telemetry attributes allowing optimal Distributed Denial-of-
Service attack mitigation. It specifies the normal traffic baseline
and attack traffic telemetry attributes a DOTS client can convey to
its DOTS server in the mitigation request, the mitigation status
telemetry attributes a DOTS server can communicate to a DOTS client,
and the mitigation efficacy telemetry attributes a DOTS client can
communicate to a DOTS server. The telemetry attributes can assist
the mitigator to choose the DDoS mitigation techniques and perform
optimal DDoS attack mitigation.
Working Group Summary
The first version of the document was published as individual draft in mid 2019.
In December 2019 the draft was adopted as a working group document.
The draft was widely discussed in DOTS WG during 2020, attracting
most active WG members.
Document Quality
Document authors are also co-authors of core DOTS documents (signal channel, data channel etc.)
The draft was reviewed by YANG Doctors (twice) and by Ops Directorate.
There are at least two interoperable implementations of the draft,
one of which participated in IETF 106 Hackathon.
