Starting next weekend, the Internet Engineering Task Force will be in London for IETF 101, where about 1000 engineers will discuss open internet standards and protocols. The week begins on Saturday, 17 March, with a Hackathon and Code Sprint. The IETF meeting itself begins on Sunday and goes through Friday.

As usual, we’ll write our ‘Rough Guide to the IETF’ blog posts on topics of mutual interest to both the IETF and the Internet Society:

Here are some of the activities that the Internet Society is involved in during the week.

IETF Journal

The November issue marked the final printed version; now, as I hope you’ve seen, we share longer-form articles online and via our Twitter and Facebook channels. Our three most recent articles are “Three Years On: Open Standards, Open Source, Open Loop” by David Ward, “Big Changes Ahead for Core Internet Protocols” by Mark Nottingham, and “QUIC: Bringing flexibility to the Internet” by Jonathan Corbet.

The IETF Journal is also now the home to this Rough Guide to IETF. The IETF Blog provides many of the day-to-day updates and reports previously covered in the printed versions of the Journal. (While you’re at it, I encourage you to read the IAB post on consolidation. It is quite a good question.)

Through the Applied Networking Research Prize (ANRP), supported by the Internet Society, the Internet Research Task Force (IRTF) recognizes the best new ideas in networking, and brings them to the IETF, especially in cases where the ideas are relevant for transitioning into shipping Internet products and related standardization efforts. Out of 55 submissions in 2018, six submissions will be awarded prizes in 2018. Two winners will present their work at the IRTF Open Meeting on Wednesday, 21 March at 9:30AM.


Right before IETF 101, the IETF is holding another Hackathon to encourage developers to discuss, collaborate, and develop utilities, ideas, sample code, and solutions that show practical implementations of IETF standards. The Hackathon is free to attend but has limited seats available.

Technologies from past Hackathons include DNS, HTTP 2.0, NETVC, OpenDaylight, ONOS, VPP/, RiOT, SFC, TLS 1.3, WebRTC, YANG/NETCONF/RESTCONF. Details on all planned technologies will be listed on the IETF 101 Meeting Wiki.

Technical Plenary

One of the week’s highlights is always the technical plenary. It will take place on Wednesday, 21 March, from 17:10-19:40. The event is live streamed at

Birds of a Feather (BoF) Sessions

Another major highlight of every IETF is the new work that gets started in birds-of-a-feather (BoF) sessions. Getting new work started in the IETF usually requires a BoF to discuss goals for the work, the suitability of the IETF as a venue for pursuing the work, and the level of interest in and support for the work. There are four BoFs happening in London:

  • Identifier Locator Addressing (ILA)
    Thursday, 22 March, 18:10-19:10
    A protocol to implement transparent network overlays without encapsulation. ILA is motivated by the need for network overlays in datacenter, virtualization and mobility scenarios that can scale to billions of nodes and be interoperable with existing infrastructure.
  • IASA 2.0 (iasa20)
    Tuesday, 20 March, 13:30-15:30
    Reviews and possibly reworks administrative arrangements at the IETF.
  • Messaging Layer Security (MLS)
    Thursday, 22 March, 15:50-17:50
    Standardizing a security protocol for encryption key establishment for use in group messaging applications, which have proliferated in recent years. While several widely-deployed applications have developed their own protocols to meet these needs, no two are close enough to interoperate.
  • Common Operations and Management on Network Slices (COMS)
    Thursday, 22 March, 09:30-12:00
    Provides an architecture and information model for the delivery of “network slices,” a 5G concept that describes a set of infrastructure resources and service functions that has attributes specifically designed to meet the needs of an industry vertical or a specific service offering.
