Starting on Sunday, 16 July, the Internet Engineering Task Force was in Prague, Czech Republic, where about 1000 engineers spent a week discussing the latest issues in open standards and protocols.

As usual, the agenda was packed, and the Internet Society is providing a ‘Rough Guide’ to the IETF via a series of blog posts on topics of mutual interest:

All these posts can be found on the Internet Society Blog, and archived via the links above in this Rough Guide page.

IETF Journal

Before we get to IETF 99, catch up on some of the highlights from IETF 98 in Chicago, Illinois, USA, by reading Volume 13, Issue 1 of the IETF Journal. You can read all the articles online at, or pick up a hard copy in Chicago.

Our cover article is a deep dive into Segment Routing, a new traffic-engineering technology being developed by the SPRING Working Group. Also in this issue, you’ll learn about the many activities of the new Education and Mentoring Directorate, which aims to enhance the productivity, diversity, and inclusiveness of the IETF. We also present an update from the Security Automation and Continuous Monitoring WGBoF updates, a readout from the pre-IETF Hackathon, a list of the tech demonstrations at the Bits-N-Bites event, and an article about the Internet Society Policy Guests to the IETF. Our regular columns from the chairs and coverage of the IETF plenary wrap up the issue.

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. In Prague, two talented researchers will present during the IRTF Open Meeting on Thursday, 20 July, at 15:50 CEST:

  • Stephen Checkoway, University of Illinois Chicago, US, for “A Systematic Analysis of the Juniper Dual EC Incident”
  • Philipp Richter, Technische Universität Berlin, DE, for “A Multi-perspective Analysis of Carrier-Grade NAT Deployment”

Right before IETF 99, on 15-16 July, 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 pre-registration is required.

Birds of a Feather (BoF) Sessions

A 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 Prague:

  • BANdwidth Aggregation for Network Access (BANANA) – would work on bandwidth aggregation and failover solutions for multi-access networks where the end-nodes are not multi-access-aware.
  • Network Slicing (NETSLICING) – would develop a set of protocols and/ or protocol extensions that enable the following operations on slices: efficient creation, activation / deactivation, composition, elasticity, coordination / orchestration, management, isolation, guaranteed SLA, OAM/Feedback mechanisms and safe and secure operations within a network environment that assumes an IP and/or MPLS-based underlay.
  • IDentity Enabled Networks (IDEAS) – would standardize a framework that provides identity-based services that can be used by any identifier-location separation protocol.
  • IASA 2.0 (iasa20) – “IASA 2.0” will review and possibly rework administrative arrangements at the IETF.
