Timeframe IETF 97 (Seoul)

Current schedule of "Important Dates" requires that all BOF proposal requests be submitted to Area Directors (ADs) by 2359 UTC Friday, 2016-09-30. The IAB and IESG will hold a joint teleconference to discuss the proposals. ADs will be expected to approve or disapprove the BOF request on that teleconference, ensuring that the Secretariat has all of the information to put the first draft of the agenda together on or before 2016-10-14.

Applications and Real-Time



BANdwidth Aggregation for interNet Access (BANANA) - Approved for IETF 97

  • 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.

There has been an informal group, also called BANANA, looking at a subset of this space: the case where multiple links are provided by a single Internet access provider/operator. Multiple solutions that could apply to this subset have been discussed within that group, including: a MIP-Based Solution (draft-ietf-dmm-mag-multihoming), an MPTCP Proxy-based solution (merged draft forthcoming), a GRE Tunnel Bonding Solution (draft-zhang-gre-tunnel-bonding), and a 3GPP-specific solution (draft-muley-bonding-solution-hybrid-access). The MIP-based solution was developed in the DMM WG and is proposed for publication as a Standards Track RFC. The GRE Tunnel Bonding solution, proposed for publication as an Independent Stream RFC, has been deployed by Deutsche Telecom in a large-scale operational network. The MPTCP solution, though not yet fully documented, presents a promising, minimal-overhead solution, especially for situations where it is only necessary to share TCP traffic between multiple links. There are significant differences between these proposals, resulting in different technical trade-offs, many of which have been explored in the BANANA Considerations Draft (draft-mrc-banana-considerations). Some of the solutions that have been under discussion may apply (with or without additional signaling mechanisms) to the broader problem space where the access links may not be provided by a single operator. This ongoing work will be discussed during the BOF, as it applies to the more general problem.

There has also been ongoing work in multiple other standards organizations to describe related problems. The Broadband Forum has produced a “Hybrid Access” problem statement for DSL/LTE bandwidth aggregation specifically for the case where the DSL and LTE links are provided by a single operator (TR-348). Documents from the other groups are not yet publicly available.

Bundled Domains (DNSBUNDLED) - Approved for IETF 97

  • Description: Bundled Domain will work on a DNS solution for fully mapping one domain name to another domain name. With the emergence of internationalized domain names and new TLDs, it is often useful to redirect one domain name tree fully to another domain name tree. Current DNS protocols have not provided such ability to satisfy these requirements.

Operations and Management

  • Name: Layer Two VPN Service Model (L2SM) - Approved for IETF 97
  • Status: Placeholder BoF. (Hope to be formed as a WG before the BoF call. Make sure a slot for it is requested in Seoul.)
  • Description: This WG would work to produce a single YANG model to describe a L2VPN service on the interface between a customer and a service provider. The WG is shaped very similar to the successful L3SM. A stake in the ground exists as https://datatracker.ietf.org/doc/draft-wen-l2sm-l2vpn-service-model/ Issue to be resolved is relationship with MEF

  • Name: IP Provisioning for SDN/NFV (ipprov) - Not Approved for IETF 97
  • Description: With the dynamic nature of SDN/NFV networks, providers and data center operators have to manage more dynamically the IP addressing and provisioning of network nodes, including various network transition scenarios such as IPv4 as a service, where IP address and prefixes consumption are critical and require timely and dynamic reallocations. An initial set of providers have expressed requirements, but with different scopes (eg: only IP addressing and prefix management and delegation, vs larger provisioning scope). Some initial prototyping of solutions and field trial has started. The intent of the bof is to gather a common set of requirements from a larger set of operators and, if needed, possible protocol work milestones and scope.
