Document: draft-ietf-ipsecme-ddos-protection-09 Multi-Path Time Synchronization Reviewer: Lucy Yong Review Date: 23-Sept-2016 IETF LC End Date: 28-Sept-2016 IESG Telechat date: 29-Sept-2016 Summary: This document is nearly ready for publication as a standard track RFC. Some minor comments. Some nits need to be corrected. PS: comment for IESG. The document specifies puzzles approach and related protocol to boost the difficulty for DDoS attacks. The protocol description is simple and short; however it spends many pages (section 7) to describe the processes at the Initiator and the Responder. Maybe in future IETF can consider accepting protocol software code in a RFC. This will be easier for author and no need for programmers to read the description and program it (sure they will not come out the same program logic). Major issues: N/A Minor issues: Section 1: 2nd paragraph, bot-nets, Comment: what is the bot-nets? Section 7.1.1.2, 1st paragraph Comment: "that must be used", should it be "that MUST be used" or "that is used"?
