This document specifies an extension to the Distributed
Denial-of-Service Open Threat Signaling (DOTS) signal channel
protocol so that DOTS clients can control their filtering rules when
an attack mitigation is active.

Particularly, this extension allows a DOTS client to activate or
deactivate existing filtering rules during a Distributed
Denial-of-Service (DDoS) attack. The characterization of these
filtering rules is conveyed by a DOTS client during an 'idle' time
(i.e., no mitigation is active) by means of the DOTS data channel
protocol.

This document is a product of the DDoS Open Threat Signaling Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
