Shepherd writeup
draft-ietf-dots-requirements

1. Summary
The document shepherd is Liang Xia. The responsible Area Director is Benjamin
Kaduk. This document defines the requirements for the Distributed Denial of
Service (DDoS) Open Threat Signaling (DOTS) protocols enabling coordinated
response to DDoS attacks. The working group has the consensus to publish it as
an informational RFC since it is a requirements draft.

2. Review and Consensus
The -00 version of this WG draft has been submitted in 2015-10, and it has
evolved into its -15 version now. The co-authors are from the leading vendors
in DDoS protection industry with extensive experience with the related
technologies and implementations, they are also the core authors of the DOTS
protocol WG drafts which guarantee the consistency among the requirements draft
with them. It has been extensively reviewed and discussed within the working
group by mailing list and github, and all technical issues raised have been
resolved, most of them are before the -10 version. This draft covers different
categories of requirements for: general, signal channel, data channel, security
and data model. The signal channel requirements is the most important and
complex one as it works during the attack time so that it requires the highest
resilience, efficiency and fault tolerance. Specially, the heartbeat handling
(SIG-004) and NAT traversal (SIG-010) issues are considered highly complicated
as they include many corner cases, and are discussed mostly in the WG. So,
careful review of them is needed. After long term discussion among the WG and
enough iteration of update, the draft is mature enough and there is strong
consensus in the WG to pass the WGLC and go to next stage.
