[saag] draft-stjohns-sipso-05 & transport protocols

[Lars Eggert <lars.eggert at nokia.com>]

Hi,

we've decided to migrate the discussion of draft-stjohns-sipso and its  
intersection with transport protocols to the SEC and TSV area lists.  
The draft is at http://tools.ietf.org/html/draft-stjohns-sipso:

	Common Architecture Label IPv6 Security Option (CALIPSO)

	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.

For those of you who haven't followed the discussion so far on the  
main IETF list, Section 7.3 of this draft proposes that TCP and SCTP  
connections are now uniquely identified by a five-tuple consisting of  
source and destination IP addresses and ports as well as the  
sensitivity label. This is obviously a pretty significant  
architectural change that deserves discussion, especially since the  
deployment of this security label architecture is likely to be very  
limited.

Lars
