Appendix A. Acknowledgments

Many ideas and even some of the text come directly from RFC 1191 and RFC 1981.

Many people made significant contributions to this document, including: Randall Stewart for SCTP text, Michael Richardson for material from an earlier ID on tunnels that ignore DF, Stanislav Shalunov for the idea that pure PLPMTUD parallels congestion control, and Matt Zekauskas for maintaining focus during the meetings. Thanks to the early implementors: Kevin Lahey, John Heffner, and Rao Shoaib, who provided concrete feedback on weaknesses in earlier versions. Thanks also to all of the people who made constructive comments in the working group meetings and on the mailing list. We are sure we have missed many deserving people.
