Focus on Security, Net Neutrality, at IETF 75From the Editor’s Desk, by Mirjam Kühne This issue of the IETF Journal is especially meaningful for me because it will be my last. After five years as editor, I am moving on to new tasks and challenges. Working with the IETF community on this publication has been one of the highlights of my career. I thank everyone who has helped with and contributed to the IETF Journal during my tenure.  The fountain outside the City Conference Centre in Stockholm. A variety of topics were covered at IETF 75, with IPv6 and the Domain Name System Security Extensions (DNSSEC) high on the list. As with IETF 74, the Internet Society took the opportunity to organize another highly successful panel, this time devoted to DNSSEC. For meeting host .SE, which has been a pioneer in the area of DNSSEC, the attention to that topic must have been especially welcome. Also in this issue we talked with Tina Tsou, the first woman to chair an IETF working group from a Chinese business enterprise, and Geoff Mulligan, chair of the IPSO (Internet Protocol for Smart Objects) Alliance. Geoff offers an interesting look at the Internet of Things and how it relates to the deployment of IPv6. Alissa Cooper and Ted Hardie discuss the history of GEOPRIV, a mechanism that develops and refines representations of location in Internet protocols; and Iljitsch van Beijnum takes us through Multipath Transmission Control Protocol (TCP), which enables TCP to use multiple paths simultaneously and to distribute the load among the subflows of each path based on congestion. Also in this issue is a summary of the administrative and technical plenaries, including a discussion on network neutrality and what the IETF can do about it. Many thanks to those who contributed to this issue; I wish enjoyable reading for all. And I look forward to seeing you all again in the future. Posted: Friday, September 25th, 2009
Multipath TCPBy Iljitsch van Beijnum As engineers, we have to build reliable systems from unreliable parts. Cables get cut, and from time to time, routers, switches, and power systems fail. Network operators address these eventualities by installing redundant connections and equipment. Routing protocols are then able to find the shortest of the multiple available paths between any two points. (more…) Posted: Friday, September 25th, 2009
Message from the IETF ChairBy Russ Housley  Russ Housley, IETF Chair I was quite pleased by the success of IETF 75. Despite the worldwide economic downturn, 1,084 people from 50 different countries attended, signifying a continuing relevance of and enthusiasm for the work of the IETF. Significant progress had been made by many of the working groups (WGs). The wonderful people at .SE hosted the meeting, which was held in Stockholm in July 2009. The meeting opened with a welcome reception hosted by Stockholm mayor Sten Nordin at Stockholm city hall, a beautiful brick edifice on Lake Mälaren. The building is reminiscent of a medieval palace and is one of the Swedish capital’s most emblematic structures; the impressive, Nobel Prize Banquet is held every December in the same room in the building. During the reception, the mayor made a toast for a successful meeting, which certainly came to pass. (more…) Posted: Friday, September 25th, 2009

Words from the IAB ChairBy Olaf Kolkman  Olaf Kolkman, IAB Chair The technical plenary at IETF meetings is organized by the Internet Architecture Board (IAB) and is considered an IAB working session. Sometimes a topic is presented because the IAB wants to get a message across to the community, sometimes we think a topic will be informative or entertaining for the IETF community, and sometimes the IAB itself wants to be informed about a topic or an issue, and we believe we would benefit from a discussion with the community. The topic of the technical plenary at IETF 75 falls into the last category. What we tried to accomplish was a more in-depth understanding of how policy and technical requirements and realities interact and how IETF technology can be designed for, or impacted by, the tussle between the two. It was not the IAB’s intention to arrive at or promote a specific position in the network neutrality debate but, rather, to more clearly understand what impact the issue may have on Internet technology.

IETF 75 Plenary ReportBy Mirjam Kühne Following a welcome address by IETF chair Russ Housley, who thanked the volunteers and contributors who had made the meeting a success, the IETF 75 administrative plenary kicked into full swing. Danny Aerts, CEO of .SE, which hosted IETF 75 in Stockholm, offered a few comments about the importance of the work being done by the IETF community and the support it receives from the Swedish local Internet community. According to Danny, a primary motivation for having .SE host an IETF meeting was that it provided an opportunity to promote DNS security. (more…) Posted: Friday, September 25th, 2009
Connecting the Dots at IETF 75By Matthew Roberts As first-time IETFers, fellows from developing regions quickly figure out the lessons to bring home.  ISOC fellows and mentors at IETF 75 in Stockholm. Despite worldwide apprehension about global economic unsteadiness, the seven Internet Society Fellowship to the IETF Programme fellows arriving in Stockholm for IETF5 75 brought with them their optimism and high expectations for a productive meeting. The fellowship programme is designed to help stimulate Internet growth in developing nations by immersing technologists from those regions in the work being done by the IETF. Each meeting, a new set of fellows, including a handful of returning fellows, are given the opportunity to improve their technical skills and become more engaged in the standards development process.

The Long Road to DNSSEC DeploymentBy Wendy Rickard A panel discussion at IETF 75 helps shed light on the need for DNS security and the reasons why it has taken so long.  IETF DNSSEC panellists at IETF 75 Few technologies are more critical to the operation of the Internet than the Domain Name System (DNS). At the time of its development—and for many years since—the DNS has functioned without many formal security mechanisms, thereby making it vulnerable to DNS spoofing and other malicious attacks. In 2008, Dan Kaminsky released his now famous bug, demonstrating how easily an attacker can trick Internet users by temporarily taking over a domain name and redirecting queries to another server.

GEOPRIV: Creating Building Blocks for Managing Location Privacy on the InternetBy Alissa Cooper and Ted Hardie Technical standards bodies that reuse the IETF’s work sometimes describe its method as creating reusable building blocks rather than whole-system architectures that are carefully tailored to specific environments. That approach has long reflected the variety of environments in which IETF protocols are required to operate. The real utility of a building block tends to surface only after reuse starts to snowball. HTTP provides an obvious example, since it’s been transporting much more than hypertext for a decade, and its success has spurred a generation of protocol designers who have reused the most portable elements of its design.

Developing Internet Technology Research and StandardsBy Leslie Daigle These days, there are a lot of activities in the world that are focused on understanding and/or developing “the future Internet.”? On one end of the spectrum are national or regional research programmes whose goals are to develop networking technologies that are free of the perceived failings of the current Internet (such as security issues, congestion, and traffic management issues); on the other end are formal specification activities within international organizations that target mainly some hypothetical other network, without regard for how that network might be deployed. However, there’s a paradox: if you can predict the future of the Internet, it’s no longer the Internet. (more…) Posted: Friday, September 25th, 2009

IRTF UpdateBy Aaron Falk  Aaron Falk, IRTF ChairSince IETF 74 the Internet Research Task Force (IRTF) has been working on IRTF RFC Stream desired copyrights. The intent is to maximize commonality with the IETF process while permitting unlimited derivative works (with attribution) or no derivative works at all. Issues to be addressed include working with the IETF Trust and establishing a correct Internet Draft boilerplate, among others. The topic is being addressed on the RFC-interest mailing list. No new RFCs have been published, but five documents are on hold pending resolution of the aforementioned copyright issues. A new research group (RG) has been chartered called the Public Key Next-Generation Research Group (PKNG), chaired by Paul Hoffman. The group will be looking into alternate certificate formats, semantics, and public-key services that could eventually replace Public-Key Infrastructure (X.509), if deployed. Discussions for an RG on network virtualization continue. (more…) Posted: Friday, September 25th, 2009
