The Protocol versus Document Points of View in Computer Protocols
This document contrasts two points of view: the "document" point of view, where digital objects of interest are like pieces of paper written and viewed by people, and the "protocol" point of view where objects of interest are composite dynamic network messages. Although each point of view has a place, adherence to a document point of view can be damaging to protocol design. By understanding both p…
Alternative Decision Making Processes for Consensus-Blocked Decisions in the IETF
This document proposes an experimental set of alternative decision-making processes for use in IETF working groups. There are a small number of cases in IETF working groups in which the group has come to consensus that a particular decision must be made but cannot agree on the decision itself. This document describes alternative mechanisms for reaching a decision in those cases. This is not meant …
