Hi, Noel, Although I appreciate your notes on this issue, IMO these terms are generall understood, and we could include these for clarity: Hard: state persists indefinitely i.e., this implies state is managed only by explicit message exchanges Soft: state is "removed" (active associations are changed to idle or non-existent) as result of time passing i.e., this implies state is managed by implicit actions, such as the passing of time in the absence of an explicit refresh This doesn't address the nuance of your discussion, e.g., whether state is a prerequisite to services. There are also other dimensions in which protocol machines differ, such as implicit vs. explicit messaging, in-band vs out-of-band, etc., but this doc isn't intended to address the general field of protocol mechanisms (or existing confusion therein).
