Hello all,

My name is Kiyotaka Takahashi.
I'm now working for PC based IPSec system in the Security Group.

I have read the draft-ietf-ipsec-arch-sec-00.txt(4 June 1996).
I have a few questions.

1) Why is a single IPsec Security Association never for both ESP and AH?
2) Is there two modes within AH, like ESP has tunnel-mode and transport-mode?

Would anyone tell me an answer to my question.

Best regards,
T.Kiyotaka
