  • IETF 111 Hackathon: Coding across time zones

    The IETF 111 Hackathon was held July 19-23, 2021. This was the 19th IETF Hackathon, and the 4th held as an online only event. For most people involved in the IETF the past several years, the IETF Hackathon marks the start of each IETF meeting.

  • IETF Community Survey 2021

    In May 2021, the IETF Administration LLC (IETF LLC) on behalf of the IESG and in collaboration with the IAB distributed the first annual IETF community survey to all 56,000 addresses subscribed to IETF mailing lists. Its purpose was "To help better understand our community and its makeup, gather views on the IETF and how well it works for participants, and gain insight into how we compare to similar organisations".

  • Experiences from the first fully-online IAB workshop on Network Impacts of COVID-19

    The Internet Architecture Board (IAB) held its first fully-online workshop in November 2019, just before the IETF 109 meeting, to discuss the network impacts of the COVID-19 crisis.

    IETF 99 Preview

    • Alissa CooperIETF Chair

    15 Jul 2017

    IETF 99 is about to kick off in Prague, Czech Republic. There is lots of exciting work going on across more than 100 working groups, plus Birds-of-a-Feather (BoF) sessions, plenary talks, and other meetings.

    Here are a few sessions to keep an eye out for:

    Pre-meeting events

    We have close to 200 participants signed up for the Hackathon taking place Saturday and Sunday. Around two dozen teams will be collaborating on code projects spanning the breadth of IETF protocols, from security to DNS to transports to IoT and more.

    Folks are invited as always to join the Code Sprint on Saturday to work on tools for the IETF community -- please join!

    Sunday afternoon's tutorial sessions will include two new technical tutorials. The TEEP tutorial will explain Trusted Execution Environments (TEE) and their associated protocol needs. The IEEE 802.1 Time-Sensitive Networking (TSN) tutorial with explain the TSN group's work on transport of data packets with bounded low latency, low delay variation and zero congestion loss, closely related to the IETF's Deterministic Networking working group.

    While not an IETF event, the Applied Networking Research Workshop, put on by ACM, the IRTF, and ISOC, is taking place on Saturday. The workshop will provide a venue for discussing emerging results in applied networking research related to measurements, transport, implementation and operational issues, and internet health metrics. (Registration required.)

    Meeting events

    Those interested in 5G may want to attend the NETSLICING BoF, which is looking at isolation of resources and virtual network functions to support a variety of services. There will also be a plenary lunch time panel on Tuesday about 3GPP and IETF collaboration on 5G in Congress Hall III.

    Other BoFs during the week: BANANA, focused on developing solution(s) to support dynamic path selection on a per-packet basis in networks that have more than one point of attachment to the Internet; IDEAS, which is aiming to standardize a framework that provides identity-based services that can be used by any identifier-location separation protocol; and IASA 2.0 where the community discussion about administrative re-arrangements for the IETF continues.

    We continue to see high interest in ongoing work related to data modeling, QUIC, and security. Catch the OPSAWG session for some discussion about managing the development and use of YANG models and the joint CCAMP/MPLS/PCE/TEAS session focused exclusively on YANG models, among other sessions. The QUIC WG will meet jointly with the HTTPBIS working group to discuss interaction between QUIC and HTTP, in addition to two meeting slots on its own. In the security area, both the TLS and ACME working groups are close to finalizing several core deliverables, and the SAAG meeting will feature a talk on post-quantum crypto.

    Thank you

    We wouldn't be able to hold IETF meetings without the support of our sponsors. Big thanks to IETF 99 hosts Comcast NBCUniversal and CZ.NIC! And to all of our sponsors for the meeting.
