         Common Architecture Label IPv6 Security Option (CALIPSO)

Status of This Memo

   This memo provides information for the Internet community.  It does    not specify an Internet standard of any kind.  Distribution of this    memo is unlimited.


   This RFC specifies the use of an IPv6 hop-by-hop option.  The IESG    notes that general deployment of protocols with hop-by-hop options    are problematic, and the development of such protocols is    consequently discouraged.  After careful review, the IETF has    determined that a hop-by-hop option is an appropriate solution for    this specific limited environment and use case.  Furthermore, the    mechanism specified in this RFC is only applicable to closed IP    networks.  It is unsuitable for use and ineffective on the global    public Internet.
