BANdwidth Aggregation for interNet Access (BANANA) BOF IETF 97, Seoul, South Korea Thursday Afternoon Session I (13:30 - 15:00) Chairs: Margaret Cullen Brian Trammell Responsible AD: Suresh Krishnan Mailing List: Discussion: banana@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/banana Archive: https://mailarchive.ietf.org/arch/browse/banana/ 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.
