Re: [shara] Preliminary agenda for SHARA BOF

Yes, right, the purpose is not to fully present a dhcp or ppp solution but just not to forget to mention somewhere:
-The issue of port range configuration
-The security issue

>From the proposed preliminary agenda:

-- Axes for discussion
       -- Impact on classes of applications
       -- Security effects
       -- Scalability
       -- Operations & Management issues

I think what Med was asking for is yet another ramification of the solution space, namely the port randomness preservation. One could argue that it fits into the 'security effects' mentioned above, but it is not limited to.

What I think is missing from the agenda is the SHARA applicability to the scenarios described in http://www.ietf.org/internet-drafts/draft-boucadair-port-range-01.txt and http://www.ietf.org/internet-drafts/draft-ymbk-aplusp-03.txt
