Technical Summary
DDoS Open Threat Signaling (DOTS) Telemetry enriches the base DOTS
protocols to assist the mitigator in using efficient DDoS attack
mitigation techniques in a network. This document presents sample
use cases for DOTS Telemetry. It discusses what components are
deployed in the network, how they cooperate, and what information is
exchanged to effectively use these techniques.
Working Group Summary
The first version of this document was published as an individual draft in
March 2020. It was adopted by the DOTS WG in September 2020. Before the
adoption the chairs had some concerns whether a separate informational
document describing use cases for DOTS Telemetry is needed or it should be
merged with the telemetry draft (based on the IESG directions to reduce a
number of supplemental documents), but the WG consensus was that it's better
to have a separate document describing use cases. The draft received
relatively little attention in the WG until the WGLC was issued, when it was
reviewed and discussed more thoroughly.
Document Quality
Document authors are long-time participants in the DOTS WG and some of them
are developers of existing DOTS implementations. The draft was reviewed by
authors of the DOTS Telemetry protocol. Some use cases described in the draft
are reportedly implemented by some vendors.
Document authors made a number of (small) fixes in response to the directorate
reviews that improved the readability of the document.
