Re: Replay field size in AH
Rodney,
The AH and ESP specs have been redone, but need another pass to
deal with some outstanding issues, e.g., the counter size issue that is
still being debated in messages from this weekend. The IPSEC architecture
document needs considerably more work.
As for AH, no, it is not going away, since, as Ran pointed out, it
still offers slightly different features as compared to ESP without
encryption. However, the motivations for using AH re more narrow than
before, due to the changes in ESP.
