The IESG has approved the following document:
- 'Distributed Denial-of-Service Open Threat Signaling (DOTS) Signal
   Channel Call Home'
  (draft-ietf-dots-signal-call-home-14.txt) as Proposed Standard

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

The IESG contact persons are Benjamin Kaduk and Roman Danyliw.

Technical Summary

  This document specifies the DOTS signal channel Call Home, which
  enables a DOTS server to initiate a secure connection to a DOTS
  client, and to receive the attack traffic information from the DOTS
  client.  The DOTS server in turn uses the attack traffic information
  to identify the compromised devices launching the outgoing DDoS
  attack and takes appropriate mitigation action(s).

  The DOTS signal channel Call Home is not specific to the home
  networks; the solution targets any deployment which requires to block
  DDoS attack traffic closer to the source(s) of a DDoS attack.

Working Group Summary

   WG support for the adoption was strong.
  The draft was well discussed and has been reviewed by many WG members.

Document Quality

  The document authors are also co-authors of core DOTS documents (signal channel, data channel etc.)
  They have good understanding of DOTS architecture so this document should fit well into that architecture.
  There are at least two implementations of the draft.

   The IANA ports expert did not see sufficient reason to allocate another port for this usage, but the WG
   has found flaws in all alternate proposals raised to date.  It is also noted that NETCONF and RESTCONF
   call home have their own dedicated port numbers, and the situation here is somewhat analogous.
