new version of ID -- IP Authentication Header (AH)

[Karen Seo <kseo@xxxxxxx>]

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
