This message starts a grow WG Call for Adoption of: 
draft-spaghetti-grow-downgrade-bgp-community-00 
 
This Working Group Call for Adoption ends on 2026-09-18 
 
Abstract: 
 This document outlines a method to mitigate Denial of Service (DoS) 
 attacks by using a well-known BGP community named "DOWNGRADE" as 
 signal to neighboring networks to treat traffic destined towards 
 "DOWNGRADE" tagged IP prefixes with low precedence.  The "downgrade" 
 strategy offers an appealing alternative to Remote Triggered 
 Blackhole (RTBH) filtering, because RTBH filtering completes the DoS 
 attack and hampers the defender's ability to monitor whether the 
 attack is still ongoing.
