YANG Catalog Latest Development (IETF 98 Hackathon)

The IETF 98 is now over. This was a successful IETF meeting in multiple ways, one of which is the IETF hackathon, two days of hacking on Saturday/Sunday.

Before delving into the hackathon results, let’s briefly review the YANG « state of the union ». As you know, YANG became the standard data modeling language of choice. Not only is it used by the IETF for specifying models, but also in many Standard Development Organizations (SDOs), consortia, and open-source projects: the IEEE, the Broadband Forum (BFF), DMTF, MEF, ITU, OpenDaylight, Open ROADM, Openconfig, sysrepo, and more. Here is a nice summary presentation “SDN and Metrics from SDOs” by Dave Ward during the Open Networking Summit 2017.

This data model-driven management applies throughout the automation « stack »: from data plane programmability with the fd.io honeycomb open-source project that exposes YANG models for VPP functionality via NETCONF and RESTCONF, to operating systems with the sysrepo open-source project (Sysrepo is a YANG-based configuration and operational datastore for Unix/Linux applications), to network control via the networking specifications in IETF/IEEE/BBF/openconfig/etc., to service models specification (YANG Data Model for L3VPN Service Delivery as an example), to controller and orchestrator and open-source projects such as openconfig), to cloud and virtualization management, without forgetting the orchestration and policy aspects (for  example, the MEF Livecycle Service Orchestration).

all-yang-modulesWith the rise of data modeling-driven management and the success of YANG as a key piece comes a challenge: the entire industry develops YANG models but those models must work together in order for operators to automate coherent services. And they must work together NOW. We don’t have the luxury to work in well planned sequences and all the modules. On one side, the YANG modules are constantly improved, and on the other side, they depend on each others.

In order to resolve this challenge, we’ve been working during IETF hackathons to provide the right open-source tools for the industry. Previous results after the IETF 97 have been highlighted.   At this IETF, a team of around 10 people went one step further by integrating tools around a YANG catalog.

Note: I went the easy way to create this blog with « we » as opposed to stress individual achievements, but many thanks to Joe Clarke, William Lupton, Einar Nilsen-Nygaard, Gary Wu, Mahesh Jethanandani, Radek Kreji,  Sudhir Rustogi, Abhi Ramesh Keshav, Carl Moberg, Rob Wilton, Miroslav Kovac, Vladimir Vassilev, and more.

What is the idea behind a YANG catalog?

From a high-level point of this YANG catalog goal is become a reference for all YANG modules available in the industry, for both YANG developers (to search on what exists already) and for operators (to discover the more mature YANG models to automate services). This YANG catalog should not only contain pointers to the YANG modules themselves, but also contains metadata related to those YANG modules: What is the module type (service model or not?) What is the maturity level? (for the IETF: is this a RFC, a working group document or an individual draft?), Is this module implemented? Who is the contact? Is there open-source code available? And we expect much more in the future. The industry starts to understand that the metadata related to those YANG modules become equally important as the YANG modules themselves. We based on work on openconfig catalog, as a starting point but we realized that we have slightly different goals.

The YANG catalog added value, compared to a normal Github repository resides in the toolchain and the additional metadata:

  • the ability to validate YANG modules (including IETF drafts) with multiple validators.
  • the related metadata regarding implementation
  • the ability to visualize the dependencies between YANG modules, including the bottleneck in case of standardization
  • the search capabilities on any YANG type and metadata, based on http://yangcatalog.org/yang-search/yang-search.php. Avoiding this way, models or model parts redefinition, which is costly to integrate.
  • the REST APIs to query and post any content
  • the demonstration of data model-driven management with open source tools:
    YANG Explorer (a GUI-based tool to explore modules, generate some code, and connect the devices)
    YANG Development Kit (a more advanced tool for code generation)

Using this one-stop set of tools, the typical flow for a YANG module designer is to validate the YANG module and to populate the YANG catalog (via an IETF drafts, via Github, or directly via the YANG catalog).

And the typical flow for a YANG module user is to search for an existing YANG module, to look up the metadata (such as maturity level, implementation, etc.), and to look up the import and include dependencies if any. Once the YANG module of choice is found, the YANG module user would browse the YANG module content, then load the YANG module in the YANG Explorer and test it by connecting to a NETCONF or RESTCONF server, and finally generate python scripts to start the automation.

This is obviously work in progress and contributions are welcome, as everything is open-source.

Practically, what have we done during this IETF 98 hackathon?

The YANG validator improved, with yanglint as an additional validator and with specific plugins that will check the correct format for the IEEE, MEF, BBF, and Cisco-specific plugins (practically, they will check the urn and prefix).

The YANG DB search laid a framework for the multi-SDO impact analysis, including a color scheme for the standard maturity levels.  Below is an example.YANG-DB-search

Regarding YANG module validation, William Lupton from the Broadband Forum added all the BBF modules to the YANG catalog, including the work-in-progress ones (this means 192 modules in total). While validating those modules, we discovered some issues with some validators. Those issues are now solved and most BBF YANG modules validate correctly. Finally, William updated the YANG catalog With the BBF modules maturity level that will distinguish draft and ratified YANG modules. The example here BBF work-in-progress YANG modules depending on the IETF interface YANG module [RFC 7223].

We created a script to push, as a cronjob, all extracted YANG modules from IETF drafts into Github (we still have to integrate it in the tool chain btw). Background: it should be a priority for the IETF to separate the draft text from its « code » content, such as a YANG module, so that we don’t have to extract YANG module via tooling, and so that the YANG module could progress in Github independently of the draft version.

Another major achievement for this hackathon is the integration of the YANG Development Kit into the YANG Explorer. In this example below, you see the YANG Explorer with the GUI on the left-hand side and the generated python script.

YANG-ExplorerIn term of YANG module transition, we also created a script to help with the latest IETF YANG module guideline: a script to convert the -config/-state into a combined tree, to convert from a combined tree to generating an additional -state tree, and to convert from a combined tree to generating an Openconfig style tree. This will be pretty handy for the transition phase, and a good addition to the toolchain.

I have personally great hope for this YANG catalog, as it will solve a real issue in this industry. Now, we should not wait until the next hackathon to continue improving it. « Running code and consensus » I heard someone say!

And finally here is Packet Pushers podcast “YANG Models & Telemetry At IETF 98”, recorded at the very end of this IETF week. Always a pleasure to speak with Ethan Banks.

Regards, Benoit (Operations and Management Area Director)

Highlights from IETF 98

The 98th IETF meeting wrapped up last Friday in Chicago. It was a typically busy work week for IETF participants, but also a special week, as a number of changes in our leadership became official. We welcomed newly selected individuals into the leadership and gave our thanks to outgoing members of the IESG, IAB, and IAOC, including the outgoing IETF Chair, Jari Arkko. Among his many other accomplishments, it was under Jari’s leadership that this blog came into existence. The blog has proven to be a useful tool for communicating with the IETF community and the world at large, and I intend to keep up the tradition. Same goes for video – you can see a clip of Jari and I recapping the meeting week here:

Amidst all the working group action and leadership transition activities, a few highlights stood out for me last week. Among more than 1000 attendees, nearly 17% were attending their very first IETF meeting this time around. We’re constantly evaluating what more we can do to attract cutting edge standardization work and new participants to the IETF, so it was nice to see many fresh faces.

Last week’s meeting demonstrated that a number of core security and web application standards are on a path towards high levels of maturity and industry adoption. These include:

The work on all of these standards is heading towards conclusion within the respective working groups, and will soon be put out for IETF community review. There was also a large TLS team at the IETF Hackathon representing 18 independent implementations, and they were named the overall Hackathon winners by the judges. Congratulations!

Last week was also very busy for those working on YANG data models related to both network management and routing. While participants continue to press forward with the standardization of hundreds of different YANG modules in the IETF, they’ve also been focusing on guidelines and tooling (yangcatalog.org, for example) to help streamline the model development process and aid interoperability.

Our technical plenary speakers, Niels ten Oever and David Clark, addressed questions about the relationship between internet protocols and human rights. David encouraged us to think of standardization activities as “designing the playing field” and to contemplate how we “tilt the playing field” based on the design choices that we make. As expected, the topic yielded a provocative community discussion session.

We owe deep thanks to our meeting host, Ericsson, for stepping up to ensure the success of last week’s meeting. As an IETF Global Host, Ericsson has committed to host three IETF meetings in a 10-year period and affirmed its long-standing support for the work of the IETF. We heard at the plenary session just how important IETF work is to Ericsson’s industry and technology goals, particularly as the coming shift towards 5G inspires potential new requirements around packet transport, network and service management, and virtualization.

Until we gather again as a group for IETF 99 in July, work will continue as always on mailing lists, at interim meetings, and increasingly on Github (check out the Working Groups Using Github session for more on that). See you in all of those places …

IETF Profile: Jari Arkko

Periodic posts on the IETF Blog highlight individuals who serve in IETF leadership roles, people who have recently begun working in the IETF, and organizations that make the work of the IETF possible. Each post aims to describe experiences working within or supporting the IETF. This one is by Jari Arkko, who will step down as the current IETF Chair during IETF 98 and begin an appointment as a member of the Internet Architecture Board (IAB).

Jari Arkko

Jari Arkko

I had my first contact with the IETF in 1996. I started working with modem pool and access server products at Ericsson. Some of what we wanted to build for our products needed standards so they could interoperate. I started working with AAA protocols and extensions. Later I became chair of the EAP, EMU, and MOBIKE working groups. These were long-term efforts that I was heavily involved in.

When I was first approached about the area director role, it didn’t sound like a feasible goal, but it grew on me. But a few years later, I applied to become an Internet Area Director. It turned out to be a perfect fit — I got to work on many topics that I really cared about, such as IPv6 transition techniques. And it was good for our company because this is the layer where our products mostly were.

I was an AD from 2006 to 2012. Six years is on the long side for this job. We tell people that four years is optimal because it takes about two years to learn the job. When I was an AD, the IETF took up 50–100% of my time. Meanwhile, Ericsson benefitted from me advising them on where the technical pieces that we cared for were heading to.

I spent the year after the AD term in the the IAB. I was already wondering if I wanted to be the IETF chair. But I knew it would be a growing experience, perhaps even a scary challenge. But I thought about it for a long time and decided to go for it.

I was IETF Chair from 2013 to 2017. And this year we are again in a situation where things are changing: I will still be at the IE, contributing, and again at the IAB.

I have personally benefitted tremendously from the involvement with the IETF. Those challenges were well worth taking!  It is a privilege to witness Internet technology in the making. .And the nature of a leadership role in the IETF demands that you see things in a broader way, talk with other companies, talk with lots of people with new ideas. It forces you to understand the bigger picture. I’ve become personal friends with lots of people in the industry, a perk I’ve enjoyed a great deal.

In a leadership role, you get the feeling that you are in the middle of important issues. As chair of one of the more active or high-profile working groups, you are doing things that are broadly visible and have an impact on the Internet. As IETF chair, I was witness to many interesting things. I am an engineer and have no interest in going into political matters. Yet observing the IANA [Internet Assigned Numbers Authority] transition was a wonderful experience, and I was glad to see how that played out.

The work of the IETF chair represents almost 100% of my efforts, although I spend a fair bit of time at Ericsson. My main role at Ericsson is to share with people what is happening in the Internet and make sure we take it into account. There were many cases, including Internet of Things technology, HTTP and encryption changes, where our business was affected by what was happening at the IETF. The company appreciates our IETF team’s involvement and expertise on these topics.

If you are thinking about applying for an IETF leadership position, my suggestion is to take the challenge! Expose yourself to new things. You will understand more, which is a benefit to both you as a person and your employer.

For me, being a leader in the IETF has underscored that we actually can make a difference. We can make significant technical changes in the Internet, or change how the Internet is administered. Yes, some of the work is hard and takes a lot of effort, but isn’t that the exciting part?

The first of these is by Alissa Cooper, current IETF ART Area Director, who will take on the IETF Chair position during IETF 98.

Alissa Cooper, IETF 96 at Intercontinental Hotel, Berlin, Germany.

I started participating in the IETF in 2008 and went to my first meeting at IETF 72  in Dublin. I was working at the non-profit Center for Democracy and Technology (CDT) in Washington, DC, where my role was to explore and articulate the technical implications of policy. I worked on a number of issues there, including online privacy.

In 2008, real-time applications were the focus of many of the consumer privacy issues of most interest to CDT. Initially, I focused on the Geopriv Working Group. I became a document author and then a co-chair of the group. It was a busy time in Geopriv – many tough battles had already been fought concerning the design of the technology, but finishing out the protocol suite required substantial effort. Over time the IETF grew into a larger portion of my job responsibilities because it was well aligned with the rest of the CDT work I was doing.

In 2011, I was appointed to the Internet Architecture Board and soon thereafter became the lead of the IAB’s Privacy Program. CDT was thrilled—they saw it as a huge honor that one of their own had been selected to serve in this capacity.

In 2013, I joined Cisco, and in 2014, I joined the Internet Engineering Steering Group as Applications and Real-Time area director. I’ve tried to do my area director work approximately half-time and my day job half-time. I’m leaving the post as I’ve been appointed IETF Chair beginning in March 2017—my new full-time role for the next two years.

Leadership in the IETF offers exposure to a broad swath of Internet technology that most of us otherwise wouldn’t be able to justify spending our time learning and influencing. This is particularly true on the IESG, but also on the IAB. It’s incredibly enriching and highly beneficial because you’re able to make connections between your day job and things going on across the whole industry.

IETF leadership also requires management skills of many kinds. You have to manage authors, your time, big community processes. It requires a lot of strategy and work in the background to achieve good outcomes. Many people do not realize the depth of the management education you get while serving in the IETF leadership.

Lastly, you get to (try to) promote your vision of what the future of the Internet should look like. Everybody might not agree with you, but serving in the leadership gives you a platform to steer and influence.

Cisco has been a big supporter of the IETF because it is deeply invested in the growth and stability of the Internet. Its customers like the idea that the products they buy from different vendors interoperate. Cisco enjoys having people in leadership positions dedicating a portion of their time to furthering interoperability and making sure that standards are keeping pace with other technological developments.

In recent years, some IETF participants have encountered difficulty in trying to convince their employers about the value of the time commitment associated with IETF leadership positions. But in reality it is possible to balance your day job with an IETF leadership role—you set the parameters for how you manage your time. Lots of positions require a half-time commitment or less.

Having a well-functioning IETF and an Internet that runs on secure, performant, interoperable standards should be pretty important to any large tech company at this point in history. If that model goes away, the options for how we replace it are all inferior. Hopefully the indirect benefits of supporting IETF leaders are obvious, but if not, current and past IETF leaders are always happy to explain the benefits. We have a big incentive to expand the population of people willing to take on leadership roles.

IETF-98 Highlights

800px-Thompson_Chicago_plat_1830

The Chicago IETF begins in a couple of days, and I wanted to point people to a few highlights from my perspective. Of course, with over hundred working groups, the IETF’s work program is quite diverse, and different people are interested in different topics. There is a lot that is particularly interesting for me:

New transport: I expect a lot of attention again on QUIC, the transport protocol designed to integrate functions from TCP and TLS. They are meeting Thursday at 09:00. They will use their meeting time to discuss the main protocol drafts, and issues such as details of the integration to HTTP. There will be a QUIC Tutorial on Sunday afternoon (15:00).

Coordinated Address Space Management: The CASM BOF will meet Monday 15:20 and discuss how organisations manage their address space and what possibly standardised tools may be useful in that.

Trusted Execution Environments: The A Protocol for Dynamic Trusted Execution Environment Enablement (TEEP) BOF meets Tuesday 14:50. They talk about a possible application layer security protocol that would allow configuring security credentials and software running on a Trusted Execution Environment (TEE). These environments are often found in set-top boxes, smart phones, tablets, wearables, etc. Current control and configuration protocols are propietary.

GitHub: More and more of networking software gets developed in GitHub, and it has also become a popular way for us to collaborate on the specifications themselves, with everyone having an ability make edits, raise issues, etc. We now have some experience from doing this, and the WGs Using GitHub (WUGH) BOF will discuss those experiences and find ways to work even better with GitHub. They meet Monday 17:10. There’s also a mailing list for discussing this topic.

YANG: In the Routing Area, YANG work continues to be of high interest. A Joint YANG session among four Working Groups (CCAMP, MPLS, PCE, and TEAS) will be held on Friday 09:00 to coordinate the work. Topics will include TE topology models, MPLS, PCE, Microwave Radio Link, and Transport. In the RTGWG, an update on the RTG YANG Architecture Design Team and work on-going in OpenConfig will be presented Wednesday 09:00.

Administrative matters: Changes to how the IETF is administered are also a popular discussions for the IETF community. The MTGVENUE working group is continuing our effort to define requirements that IETF meeting sites must fulfill, which seems even more important among the increasing number of travel restrictions. The IETF needs to stay as open as possible for all attendees. The group recently went through some changes. The group meets Monday 15:20. And the IASA 2.0 BOF asks whether there should be adjustments or even restructuring of the IETF administrative arrangements overall. Our arrangements have served us well, but there are also issues, and with 10+ years of experience it is time to re-assess the system. We held two workshops earlier on this topic, and the results of those workshops are outlined in an Internet-Draft. The group meets Wednesday 13:00.

New leadership: The IETF Nominations Committee (Nomcom) is charged with selecting persons for the various IETF leadership positions. The changeover is in the March meeting. For our steering group, Eric Rescorla, Adam Roach, and Warren Kumari will be starting as new Security, Applications and Real-Time, and Operations Area Directors. And I will be stepping down after four yours as chair, with Alissa Cooper continuing in that role. Please welcome the new chair and ADs! And thank you for volunteering to do this!

Running code. Last but not least, none of the above matters without software that actually does those things. Our Hackathon and Code Sprint events are open for everyone to attend, do join us and work on something that is important to you or your business! Both events start Saturday morning (09:00/09:30) before the IETF. The Code Sprint is the way that much of IETF’s own web systems and tools have come about. I want to emphasise how much we depend there both on volunteers as well as capable contractors — we need you. There are also many side events during an IETF, for instance the network operators meeting (IEPG, Sunday 10:00).

ericsson-logo-100x I also wanted to thank all our sponsors and supporters, and Ericsson in particular for hosting us in Chicago.

The sponsors make our meetings and IETF services possible. Thank you!

See you soon, and I wish everyone safe travels to Chicago. Hopefully the effects of various last-minute restrictions (such as the laptop ban on some flights) will remain minimal. And those participating in the meeting online — see you virtually soon!

University Students Create Running Code for the Internet

IETF 97 Hackathon pano

IETF Hackathons embody the IETF’s tradition of running code—testing theories against the realties of implementation, with a goal of accelerating the definition and adoption of protocols and technologies that make the Internet work better. One of the best things about theses events is the shared success of a broad range of participants, from long-time IETF contributors to those who have never attended an IETF meeting or joined an IETF working group. Of particular note, university students from around the world have been remarkable contributors at the past few hackathons.

Team from Sungkyunkwan University IETF Hackathon at IETF 97

Team from Sungkyunkwan University IETF Hackathon at IETF 97

At the most recent IETF Hackathon in Seoul, a team from Sungkyunkwan University worked on implementations of the specifications being defined with the Interface to Network Security Function (I2NSF) Working Group. Powered by energetic professors and students from Sungkyunkwan University in South Korea, the team used RESTCONF and NETCONF together with YANG data models to implement network security services using OpenDaylight and mininet. In doing so, they validated the approach defined by the IETF’s I2NSF Working Group.

Charles Eckel, an Open Source Developer Evangelist for Cisco DevNet, who has led the IETF Hackathons over the past few years, has witnessed first hand how teams with a diverse set of participants often leads to impressive results. Eckel commented, “The most successful hackathon teams are those with a good mix of participants with different skillsets. When you combine IETF newcomers with great coding skills with IETF veterans with tremendous knowledge of evolving Internet protocols—that’s where the magic happens.”

IETF Hackathons provide students with unique learning opportunities as well. Eckel observes, “The mentoring and teamwork that comes from working closely with a group of people on a focused effort over the course of two days is a rich and valuable experience that you are not likely to get merely by reading a few drafts and attending a handful of meetings.”

On numerous occasions, even the hurdle of geography has been cleared by hackathon participants. For example, Ecole Polytechnique de Louvain in Belgium organized two teams working on Multipath TCP during the IETF 97 Hackathon in Seoul. Five participants in Seoul, including three PhD students, worked with 25 students in Louvain-la-Neuve on a new socket API that allows application developers to more easily make use of multipath TCP subflows. Together, the teams received the Best Overall award for the hackathon.

The result confirms Eckel conclusion that, “IETF Hackathons are great events for both long-time IETFers and well as newcomers. “

The next IETF Hackathon will be held in Chicago on 25-26 March 2017. As Eckel notes, “For someone with coding skills and an interest in working on the Internet, IETF Hackathons provide opportunities to get plugged into a project and immediately start producing tangible results.”

Observations on the CIA Revelations

TOXIC SPILL, AJKA, HUNGARY-OCTOBER 9, 2010

Recent news stories, and some IETF list discussion, have related to the release of (claimed) CIA materials relating to surveillance, hacking and information warfare. There has been quite a bit of discussion about the details of the various attacks contained in this leak, such as those relating to surveillance through smart TVs, or hacking vehicles. But are there more general conclusions that we can draw from release of this information?

First, we think the content of leaks is not particularly surprising, especially given knowledge of other leaks in recent years, such as those from Edward Snowden. Malware is another tool in the same toolbox that is already known to include many other efforts that attempt to compromise security, such as pervasive surveillance.

But the release of the current tranche of documents does seem to nicely support a number of things that we knew already and that are arguably more worthy of consideration:

  1. Security is not a single feature, rather the level of security one experiences needs to be thought of as an emergent property of the whole system. Communications security, for instance, is necessary but not sufficient. You also have to worry about the security of your devices, platforms, operating systems, and components. And the reliability of your communication partners.
  2. There is no such thing as privileged access for the good guys once there are more than a very small number of people involved. Sooner or later the privileged way to access information or hacks will either leak, be re-discovered independently by others, or be shared to parties that do not have your best interest in mind. In addition, systems built to take advantage of the privileged access will get broken and misused.
  3. All malware is just that, malicious software designed to disrupt or compromise other systems. And all will eventually leak. Secretly held knowledge of vulnerabilities makes us all less safe. The vulnerabilities will be exploited, perhaps traded or shared, instead of being reported and fixed. And when they leak out, they do damage to your friends as well as your supposed enemies.
  4. The security of our communications and applications matters a lot. Lives are at stake, not just your browsing history. Our entire societies run on top of our technical infrastructure, from hospitals and power plants to political processes and our economy. We cannot afford to compromise the security of these systems.

As noted, we think these are matters that are already known, but reminding ourselves of the big picture now and then can be useful.

From the IETF perspective we are of course committed to continuing our effort to provide the best possible technical tools for the Internet and the users. One technical observation that may be of use is that focusing on protecting data and not merely links or transport needs better support, make it easier to achieve in practise and at scale.

Reviewing and Assessing the IETF Administrative Support Activity

Ranakpur-Jain-Marble-Temple-pillars-Frescoes-Apr-2004-02

The current IETF Administrative Support Activity (IASA) arrangements were created more than ten years ago when the IETF initially took charge of its own administration [1]. The arrangements have served the IETF well, but there’s been considerable change in the necessary tasks and in the world around us since then [2]. What administrative arrangements will best support the IETF going forward?

A series of virtual workshops have been arranged as part of an effort, dubbed the IASA 2.0 project, to gather community input as part of a review and possibly rework of IASA arrangements.

The workshops will help understand what is working well and what challenges or missed opportunities exist in the current system. We also want to understand what the IETF will need in coming years. Possible topics include:

  • internal IASA and IAOC organizational issues;
  • roles and interfaces between the IETF, the IAOC, ISOC, the IESG, and contractors;
  • availability of staff, contractor, and volunteer resources compared to the administrative workload;
  • finance and sponsorship arrangements.

The workshops will be virtual meetings where the participants can provide their experiences and suggestions. Proposed changes and solutions will be dealt with in a later phase [3]. Meeting notes and an Internet Draft summarizing the input will be produced afterwards.

The agenda will be the same for both workshops, which are scheduled to accommodate participants in different timezones:

IASA 2.0 Workshop 1
Tuesday, 28 February 2017

New IESG

Every year, the IETF selects its leadership through the nominations committee or NomCom process. Today, the committee has announced our new steering group (IESG) members.

The new members are Alissa Cooper (Cisco), who will be new IETF Chair as I am stepping down. Warren Kumari (Google), will be our new Operations and Management Area AD. And Eric Rescorla (Mozilla) becomes the new Security Area AD. Together with the continuing ADs, this is a great team, and the IETF is in extremely capable hands!

When the new members get seated, we will be saying goodbye and thank you to two long-serving ADs: Stephen Farrell (TCD) in the Security Area and Joel Jaeggli (Fastly) in the Operations and Management Area. Their service to the community, dedication to making the Internet better, and rational approach to contentious issues have made the IESG, the IETF, and the Internet better.

Notably, with these appointments we’ll be continuing to demonstrate gender diversity in our leadership. Not only has Alissa been selected as the first female chair, but we’ll continue to have five female area directors serving in the IESG, the most we’ve had at one time. They are in these roles because they are the best people for their roles, but I think this also sets a great example for other tech organisations to follow in gender diversity :-) I would like to challenge other standards organisations to top our results.

More information in the announcement.

Jari Arkko, IETF Chair for two more months :-)
