Internet Architecture Board


About the Internet Architecture Board

The Internet Architecture Board provides long-range technical direction for Internet development, ensuring the Internet continues to grow and evolve as a platform for global communication and innovation.

In its work, the IAB strives to:

  • Ensure that the Internet is a trusted medium of communication that provides a solid technical foundation for privacy and security, especially in light of pervasive surveillance,
  • Establish the technical direction for an Internet that will enable billions more people to connect, support the vision for an Internet of Things, and allow mobile networks to flourish, while keeping the core capabilities that have been a foundation of the Internet’s success, and
  • Promote the technical evolution of an open Internet without special controls, especially those which hinder trust in the network.

Appointment to the Internet Society Board of Trustees

As set out in RFC 3677, the IAB is responsible for selecting a certain number of the Trustees who serve on the Board of the Internet Society.

In fulfillment of that responsibility, we are happy to announce that Richard Barnes has been selected for a three year term, to begin at ISOC’s annual general meeting in June.

The IAB had a very strong set of candidates this year, and we would like to express our appreciation to each of them for their willingness to serve.  We look forward to their continued engagement with the Internet Society and the IETF.

Call for nominations: IRTF Chair

As part of its oversight responsibility for the Internet Research Task Force (IRTF), the IAB is responsible for selecting the IRTF Chair.

The IRTF focuses on longer-term research issues related to the Internet, organizing its work into topical Research Groups (RGs). The IRTF Chair is selected by the Internet Architecture Board (IAB). It is a volunteer position with duties that include: 1) strategically shaping the work undertaken by IRTF RGs, 2) managing administrative responsibilities such as those related to publishing RFCs via the IRTF stream, and 3) serving as an ex-officio member of the IAB. The IRTF Chair should have previous experience in network research. Experience in operational management or implementation is beneficial. It is also desirable for the IRTF Chair to be familiar with the Internet Engineering Task Force (IETF), the IAB, and related groups and processes.

The current IRTF Chair, Lars Eggert, has indicated that he plans to step down from this position in March 2017.

The IAB is currently soliciting nominations for the IRTF Chair, for a term beginning at IETF 98 in March 2017 and ending at IETF 104 in March 2019.

A description of the IRTF Chair role can be found in RFC 7827, “The Role of the IRTF Chair.”

Report from the IAB before IETF 95

Dear colleagues,

This is the report to the community from the IAB about our activities since IETF 94 (which was in Yokohama). We used to go over much of this sort of material in the plenary sessions. Shorter time for plenary sessions in the weekly agenda led us to try this form of report, and it was popular. So we are continuing with it. We hope that this form allows you to prepare topics you might want to discuss during the open mic. But of course, if you have views you want to make known by email, we’re easy to reach: send mail to to reach our public discussion list, and to reach just the IAB. Continue reading

IAB Appoints Adam Roach to RFC Series Oversight Committee (RSOC)

After reviewing the strong list of individuals who offered to serve on the RFC Series Oversight Committee (RSOC), the IAB is pleased to appoint Adam Roach to serve on the RSOC.

The IAB extends many thanks to the community members that were willing to serve on the RSOC for their ongoing support of the RFC Series and the RFC Series Editor.  The IAB also wishes to thank Alexey Melnikov, who is  stepping down from the RSOC to join the IESG in April.

RFC 7754 on Technical Considerations for Internet Service Blocking and Filtering

The IAB has published RFC 7754: Technical Considerations for Internet Service Blocking and Filtering.

Abstract: The Internet is structured to be an open communications medium. This openness is one of the key underpinnings of Internet innovation, but it can also allow communications that may be viewed as undesirable by certain parties. Thus, as the Internet has grown, so have mechanisms to limit the extent and impact of abusive or objectionable communications. Recently, there has been an increasing emphasis on “blocking” and “filtering”, the active prevention of such communications. This document examines several technical approaches to Internet blocking and filtering in terms of their alignment with the overall Internet architecture. When it is possible to do so, the approach to blocking and filtering that is most coherent with the Internet architecture is to inform endpoints about potentially undesirable services, so that the communicants can avoid engaging in abusive or objectionable communications. We observe that certain filtering and blocking approaches can cause unintended consequences to third parties, and we discuss the limits of efficacy of various approaches.
