Network Working Group M. StJohns Request for Comments: 5570 Consultant Category: Informational R. Atkinson Extreme Networks G. Thomas US Department of Defense July 2009 Common Architecture Label IPv6 Security Option (CALIPSO) Abstract This document describes an optional method for encoding explicit packet Sensitivity Labels on IPv6 packets. It is intended for use only within Multi-Level Secure (MLS) networking environments that are both trusted and trustworthy. 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. IESG Note 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.
