Technical Summary
This document specifies the Distributed Denial-of-Service Open Threat
Signaling (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 document obsoletes RFC 8782. The major change is to use YANG structures
instead of an ad-hoc construction.
Working Group Summary
Shortly after RFC 8782 was published in May 2020 a problem with a YANG module defined in it was discovered.
The WG decided to publish a -bis document to fix the problem. The -00 version of the draft was prepared
fairly quickly (in June 2020) and the document was adopted in August 2020 (with a good WG support for adoption).
The draft has been widely discussed and reviewed.
Document Quality
This draft is a -bis document for RFC 8782, its main purpose is to fix YANG module. In addition it provides more
comprehensive description of error handling and makes minor changes to DOTS CBOR Key Values allocation.
This document doesn't change the DOTS Signal Channel protocol itself, in particular it doesn't change bits on the wire.
DOTS Signal Channel protocol was thoroughly discussed and reviewed. There are at least two interoperable implementations of this protocol.
The updated YANG module has been reviewed by YANG Doctors, who confirmed that they don't have problems with it.
