We had 1,426 on-site participants from 62 countries—more attendees than we’ve seen in a long time from more countriesI than we’ve ever had. There were 12 new working-group proposals, and although many were taken to the discussion stage quite early, many of those seem to have experienced positive results. I anticipate that about two-thirds of the proposals Jari Arkko, IETF Chair will soon be up for approval as working groups. In addition to new work, IETF 87 attracted a record 316 first-timers. This is great news—new people are vital to ensuring we understand the myriad challenges of Internet technology. IETF 87 also saw the debut of our new mentoring system. Approximately 50 IETF attendees volunteered to mentor new attendees: help them navigate the meeting and, most important, establish connections with others. For me, an important aspect of each meeting is the interaction I have with people who are building devices on the Internet. Specifics aside, this kind of like-minded networking is a crucial part of setting up new, interop- erable Internet technology and a vital part of each new attendee’s IETF experience. In addition to new work, IETF 87 attracted a record 316 first-timers. This is great news—new people are vital to ensuring we understand the myriad challenges of Internet technology. We had a great social event, thanks to DENIC, our platinum sponsor. I’ve yet to meet an engineer who doesn’t love trains. Everyone in attendance had a wonderful time. Thank you, DENIC! And this meeting’s Bits-n-Bites was so well attended that at times it was difficult to get to the demo tables. Many thanks to all of our event sponsors: A10 Networks, ADVA Optical Networking, Comcast, Deutsche Telekom, Dyn, ECO, EURid, Huawei, ICANN, the Internet Society, IPSO Alliance, and Nominum. We couldn’t do it without you. The practical meeting organisation worked well. In fact, participants liked the hotel and the facilities so much that many suggested we return to Berlin soon. From a personal perspective, some of the most interesting work that occurred this meeting included work related to the Internet of Things (many of the new work proposals were in this space), home networking (also some new proposals and a lot of running code), and multimedia communications from browsers (WebRTC). I also liked the new Advanced Queue Management (AQM) work proposal, which attempts to keep bad router buffering practices from wasting capacity. This group has a real chance of improving how responsive the Internet feels to individual users without requiring an increased broadband connection speed. During the meeting, we continued our discussion of technical and organisational issues. In our adminis- trative plenary, Kathleen Moriarty and Suresh Krishnan updated us on the Diversity Design team’s activities (page 9). These discussions are on a productive path. I’m looking forward to the improvements we’ll make in this space. Continued on page 4 The mission of the Internet Engineering Task Force is to make the Internet work better by producing high-quality and relevant technical documents that influence the way people design, use, and manage the Internet.

Olaf Kolkman and Bernard Aboba left large shoesT to fill—over the past few years, they restructured the way the IAB works by introducing the new program model that greatly improved the ability of the IAB to simultaneously handle administrative, liaison, and technical responsibilities. Russ Housley, IETF Chair I greatly appreciate the support of the IAB and the entire Internet community. Appointments In July, the NomCom announced the appointment of Erik Nordmark to the IAB, filling the seat vacated by Spencer Dawkins, who accepted the Transport Area Director position. The IAB thanks Spencer for his service. The IAB appointed Bob Hinden to another term on the Internet Society Board of Trustees. During the Board meeting in Berlin the day after IETF 87, Bob was elected chair of the ISOC Board. Congratulations Bob! Two liaison manager positions closed. The IAB thanks Fred Baker for serving as liaison manager to the Smart Grid Interoperability Panel (SGIP) and Richard Barnes for serving as liaison manager to IEEE 802.23. There has been turnover in three liaison manager positions: the IAB appointed Scott Mansfield as the IETF Liaison Manager to the ITU-T, replacing Eliot Lear; it appointed Deborah Brungard as the IETF Liaison Manager to the ITU-T for Multiprotocol Label Switching (MPLS), replacing Scott Mansfield; and it appointed Jonne Soininen as liaison to the Internet Corporation for Assigned Names and Numbers (ICANN) Board, replacing Thomas Narten. The IAB thanks Eliot and Thomas for their service as liaison managers. Highlights since IETF 86 The IAB sent letters on open standards in the Transatlantic Trade and Investment Partnership (TTIP) to both the U.S. government and the European Commission. You can find these letters on the IAB website.1,2 The IAB published a statement entitled, “Dotless Domains Considered Harmful.” You can find the statement on the IAB website.3 The IAB responded to the ICANN Consultation on the Source of Policies and User Instructions for Internet Number Resource Requests. You can find the response on the IAB website.4 Appeal to the IAB The IAB received an appeal from JFC Morfin regarding RFC 6852 on 8 July 2013 and answered the appeal on 17 July 2013.5 Upcoming IAB Workshop The IAB is sponsoring a workshop on Internet Technology Adoption and Transition (ITAT). The workshop will be held on 4–6 December 2013 in Cambridge, UK. Participants were required to submit 3–10 page interest statements by 29 August 2013.
