New Work in Seoul


A month before the meeting our steering group collects proposals for new working groups. We decide which ones are ready enough for the community to discuss the proposals in the meeting. We did this last week, and I wanted to report what new meetings will be held.

There are also a number of new working groups that have had their community consideration earlier, and are being considered to be created, or were recently created. I will also mention some of these working groups.

Here are the new meetings:

  • The QUIC working group has just been chartered, and will meet for the first time in Seoul. This working group is taking Google’s pre-standardization QUIC protocol that has been deployed in production for several years, and will use it as a starting point to develop a UDP-based, stream-multiplexing, encrypted transport protocol with standardized congestion control, TLS 1.3 by default, a mapping for HTTP/2 semantics over QUIC, and multipath extensions. This is the IETF’s first standardized always-encrypted transport protocol, so careful consideration of applicability and operational capabilities will be key for success.
  • DNSBUNDLED will be having a non-WG forming BOF in Seoul. The responsible AD is Terry Manderson, with Andrew Sullivan as the IAB Shepherd. DNSBUNDLED is concerned with a problem statement of mapping and maintaining one DNS domain and all of its underlying name structure into another domain. The following related use cases have been proposed: 1) map across TLDs such as to; 2) map different label within a TLD, i.e to; 3) map different labels across different TLDs, for instance to, and lastly 4) where multiple domains map to one domain such as,, all map to example.gTLD. The mailing list for this BOF is here and one of the Internet Drafts on this topic is here.
  • BANdwidth Aggregation for interNet Access (BANANA) will be having a non-WG forming BOF in Seoul. BANANA is concerned with providing coordinated Internet Access to a device over multiple links of different types to allow for increased bandwidth utilization, load-balancing and/or higher reliability. The goal of this BoF is to come up with a shared understanding of the problems that the IETF would like to solve in this space, complementing on and in collaboration with work ongoing in the MPTCP working group and the Broadband Forum. The group’s mailing list is here.
  • IPWAVE is a new working group, focusing on communications in vehicular networks. Vehicles are increasingly connected to the Internet. Comfort-enhancing entertainment applications, road safety applications using bidirectional data flows, and connected automated driving are some of the few new features expected in this area. This group will work on use-cases where IP is well-suited as a networking technology and will develop an IPv6 based solution to establish direct and secure connectivity between a vehicle and other vehicles or stationary systems.
  • LPWAN is a new working group that is focused on running internet protocols on a Low Power Wide Area Networks. There are several very diverse LPWA lower layer technologies such as NB-IoT, SIGFOX, LoRa, and WI-SUN. and The goal of this working group is to converge these radio technologies towards a common hour glass model, with a highly compressed form of IPv6 and CoAP between the end-device and the network gateway. This will enable the creation of common mechanisms for management of the gateway and for providing secure, Internet-based services to the applications.
  • L2SM is a proposed working group, currently under consideration. It is intended as a short-lived WG, tasked to create a YANG data model that describes a L2VPN service (a L2VPN service model) that can be used for communication between customers and network operators, and to provide input to automated control and configuration applications. The working group will attempt to derive a single data model that includes support for point-to-point Virtual Private Wire Services (VPWS) and multipoint Virtual Private LAN services (VPLS) that use Pseudowires signaled using the Label Distribution Protocol (LDP) and the Border Gateway Protocol (BGP) as described in RFC4761 and RFC6624.
  • SECEVENT is a new working group. The group works on a mechanism to convey messages between systems in order to prevent or mitigate security risks, or to provide out-of-band information as necessary.
  • SIDROPS is another new working group currently under consideration to be created. This group discusses operational experiences around the global deployment of RPKI, Origin Validation of BGP announcements and BGPSEC, collectively called SIDR. This technology helps protect the Internet routing infrastructure against various kinds of attacks.

Join our meeting to discuss these and many other interesting topics! If you haven’t registered yet, you can do so on the IETF-97 web page.
