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.
