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).
