new version of ID -- IP Authentication Header (AH)
Folks,
A new version of the AH ID has been submitted to the IETF
secretariat. In addition to some clarifications, this draft differs
from the previous AH spec (RFC 2402) as follows:
o SPI -- modified to better reflect the differences between
unicast and multicast SA lookups. For unicast, the SPI may
be used alone to select an SA; for multicast, the SPI is
combined with destination address to select an SA.
o Sequence number -- added a new option for a 64-bit sequence
number for very high-speed communications.
Thank you,
Karen
