BOF Description: 
This BOF will discuss how we can take advantage of multiple access
links, provided by one or more access providers, in cases where end
nodes and applications may not be multi-access-aware.  Use of multiple
access links could provide bandwidth aggregation when multiple links
are available (i.e. improved performance), and session continuation
when a link becomes unavailable (i.e. increased reliability).

Solutions to this problem are intended to apply to home and
small-office networks, so solutions must support load-sharing of a
small number of flows (in some cases only one) over multiple paths,
recombining the traffic in ways that do not cause problems for the
network (i.e. congestion, multi-level retransmission, etc.) or for
upper-layer protocols (i.e. packet reordering within flows).
Solutions in this area must allow for some traffic to bypass bandwidth
aggregation (e.g. for flows that are mandated to travel a specific
path, or for flows that are already using a more end-to-end bandwidth
aggregation solution).  Solutions should provide minimal (if any)
performance degradation when multiple links are not available, or when
one or more of the links is not performing sufficiently to support
increased performance to the end nodes.

This is a Non-WG-forming BOF.  The purposes of the BOF are to discuss
the problem space, and determine if there is sufficient interest and
energy in the IETF to pursue any work in this area.  If the interest
and energy exist, further effort may be exerted to scope and charter
an IETF WG.
