Getting new work started in the IETF usually requires a birds-of-a-feather (BoF) meeting 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. In this article, we’ll review the BoFs that took place during IETF 86, including their intentions and outcomes. If you’re inspired to arrange a BoF meeting, please be sure to read RFC5434: Considerations for Having a Successful Birds-of-a-Feather (BoF) Session.

IETF 86 was a well-attended, successful meeting. At last count, 1,071 people came from 51 countries to Orlando, Florida, and actively engaged in making the Internet work better. I was thrilled to see so many people collaborating.

NBCUniversal and Comcast hosted IETF 86. The hotel facilities were very comfortable, and the social on Tuesday set a new bar for future hosts. IETF participants experienced the magic of the Wizarding World of Harry Potter at Universal Orlando Resort. Thanks so much for your support!

Closing the Circle

During IETF 86 in Orlando, Florida, U.S.A., six chartered Internet Research Task Force (IRTF) research groups (RGs) held meetings:

The pending demise of plain old telephone service (POTS) will result in the Internet engineering community grappling with upcoming technical challenges and possibly writing new standards, according to Henning Schulzrinne, chief technology officer for the U.S. Federal Communications Commission.

Schulzrinne discussed this issue at the technical plenary of the IETF meeting in Orlando, Florida, this past March.

Whether or not the Internet engineering community should create a standard mechanism for content creators to articulate how they want their original works to be used by others online was the topic of a panel discussion sponsored by the Internet Society in March.

The topic of Software Defined Networking (SDN) has attracted a great deal of attention from service providers, enterprises, and industry associations. A true picture of SDN has yet to emerge, however, despite today’s enthusiastic expectations.

Imagine that you could open your web browser, click on a link or a button, and start a voice/video conversation with a friend or play a multiplayer game without requiring the installation of an external plugin—no Flash, no Java, no any other plugin technology. Now imagine that this same conversation or game involves high-quality, wideband audio, HD video; has a chat component, as well as a way to share data; and is entirely secured by encryption.

The Internet Research Task Force (IRTF) has been host to some of the most interesting talks offered at recent IETF meetings thanks to the presentations given by winners of the Applied Networking Research Prize (ANRP). At the IETF86 meeting in Orlando, Florida, Gonca Gürsun, a Ph.D. student from Boston University and the most recent recipient of the ANRP, discussed a new metric for analysing the structure of Internet routing.

We’re pleased to introduce Jari Arkko, Ericsson expert in Internet architecture and the new IETF chair. As a way of sharing more about him and his vision for the post, we’ve excerpted here posts from of his newly created IETF Blog (  

The 86th meeting of the Internet Engineering Task Force took place in sunny Orlando, Florida, U.S.A. IETF meetings are week-long affairs packed-full of interesting presentations and discussions—the IETF Journal can merely provide a snapshot of the proceedings and the people who helped make IETF86 another great meeting. If there’s some aspect of IETF that you’d like to read more about, please let us know.

Back in the last millennium, the IETF published an informational document (RFC 2309) that provides two important recommendations concerning measures to improve and preserve Internet performance. The first of these recommendations concerned the need for active queue management (AQM) to reduce the number of dropped packets, and to provide better service for low-delay, interactive flows. The primary goal of AQM algorithms is to allow network operators simultaneously to achieve high throughput and low average delay by detecting incipient congestion.

Recently, a Swiss journalist contacted us at the Computer History Museum (CHM) seeking records of the start of the Austrian .AT domain in the 1980s. I asked Elizabeth “Jake” Feinler, an Internet pioneer and ISOC Hall of Famer who gave the Museum records from the NIC (Network Information Center) that she ran for nearly 20 years. Jake is a core advisor to our Internet History Program.

The IETF Journal honors the memory of Dr. Douglas C. Engelbart, noted computer andInternet pioneer, who passed away on 2 July 2013. Pivotal in helping to define computing as we know it today, he is perhaps best known as the creator of the computer mouse.
