Technical Summary
This document specifies the DOTS signal channel, a protocol for signaling
the need for protection against Distributed Denial-of-Service (DDoS)
attacks to a server capable of enabling network traffic mitigation on
behalf of the requesting client.
This is a companion document to the DOTS data channel specification.
Working Group Summary
This draft has been extensively reviewed and discussed within the
working group by mailing list and github. The latest document is
well written and reaches a broad consensus in WG.
Document Quality
The co-authors are from some of the leading vendors and operators in
DDoS protection industry with extensive experience with the related
technologies and implementations; they are also the core authors of
the DOTS requirements WG drafts, which guarantees consistency between
the core DOTS protocol documents. Until now, there are three demo
implementations for it (open source go-dots from NTT and two
proprietary demos from NCC and Huawei), and several rounds of interop
tests during IETF hackathon activities. All the technical issues
identified by these demos and the finished tests have been addressed
and reflected into the latest draft, which are very helpful for the
completeness and quality improvement of the draft.
IANA port number expert review is ongoing; the expert is seeking
additional justification that a dedicated port is needed, which has
been provided by the document authors.
