[anonsec] Dan's comments (Re: Connection Latching draft review (draft-ietf-btns-connection-latching-04.txt))

[Stephen Kent]

Nico & Dan,

the SPD has always been a persistent database. the newly added PAD 
also is persistent. It's the SAD that is transient, i.e., need not 
have any entries unless SAs have been created, and those entries 
vanish when the SAs they represent vanish. The notion of dynamic 
modification of the SPD is a relatively new concept, not part of the 
original design, but not ruled out by it. Also note that the 
de-correlated SPD model introduced in 4301 works very well for a 
persistent database, but could be costly to maintain if the SPD is 
frequently updated.

Steve has indicated that he is tired of reviewing BTNS documents that 
often are hard to read and that too often are revised with only 
slight improvement. The BTNS problem statement is the most recent 
example, where comments from two years ago were not acted upon.
