Howdy,
I've just posted a new mobility/multi-homing proposal as an internet-draft.
The multi6 mailing list is probably the most appropriate venue for
discussing this proposal, so it is the only address showing in the TO
field. However, I have blind cc'd additional lists, for notification:
ietf, because of a current thread about end point identifiers
HIP, since my proposal is related to theirs
end-to-end, since that's what this is about.
The I-D name is:
draft-crocker-mast-proposal-00.txt
It is also available at:
<http://brandenburg.com/specifications/draft-crocker-mast-proposal-00.txt>
Herewith the abstract for the proposal:
Classic Internet transport protocols use a single source IP
address and a single destination IP address, as part of the
identification for an individual data flow. TCP includes
these in its definition of a connection and its calculation
of the header checksum. Hence the transport service is tied
to a particular IP address pair. This is problematic for
multi-homed hosts and for mobile hosts. Both have multiple
IP addresses but cannot use more than one, for any single
transport association (context). Multiple Address Service
for Transport (MAST) defines a mechanism that transparently
supports association of multiple IP addresses with any
transport association. It requires no change to the IP
infrastructure, and no change to IP modules or transport
modules in the end-systems. Instead, it defines a wedge
layer between IP and transport that operates only in the end
systems and affects only participating hosts.
As the document notes a couple of times, this is an extended proposal,
rather than a complete specification. It's being put forward in the
current form to solicit comments about the approach and the design, and
to find out whether folks are interested in pursuing it further.
