Video and Slides Now Available For My AstriCon 2015 Keynote: Open Source and The Global Disruption of Telecom

If you're interested in what I said last month at AstriCon 2015 in my keynote on "Open Source And The Global Disruption of Telecom: What Choices Will We Make?", the video and slides are both available.

As I wrote about previously, the context for this discussion was to talk about the changes that are happening all around us in terms of the ways in which we communicate. Here was the abstract:

There is a battle raging for the global future of telecommunications and the Internet. Taking place in networks, board rooms and legislatures, the battle will determine how we all communicate and what opportunities will exist. Will telecom support innovation? Will it be accessible to all? Will it give us the level of security and privacy we need to have the open, trusted Internet? Or will it be restricted and limited by corporate or government gatekeepers?

The rise of voice-over-IP has fundamentally disrupted the massive global telecommunications industry, infrastructure and policies. Open source software such as Asterisk has been a huge driver of that disruption and innovation.. but now what? What role do platforms such as Asterisk play in this space? And what can be their role in a telecom infrastructure that is now mobile, increasingly embedded (Internet of Things) and more and more using proprietary walled gardens of communication?

How well I delivered on that will be up to you to decide... but I felt good about how it all came out and received many great comments and feedback throughout the rest of the event and afterwards. And, as a speaker I could see from the crowd (about 500-ish people) that they were NOT looking down into their smartphones or laptops... which is always a good sign! ;-)

A key point of what I aimed to do was to bring people up to a higher level to think about how their own actions fit into the broader context of what is happening in the world today.

It was fun to do! And I loved all the questions I was getting after that. My goal was to make people think... and it seemed that at least for some I did.

My part of the video starts after 15 minutes of introductory items (this was the opening of the event), so if you watch in the embedded video below you'll need to move forward to the 15:00 mark. You can also follow this direct link to the start of my segment with an introduction to me from Mark Spencer, the creator of Asterisk.

(And yes, this was the first time I had ever given a presentation wearing a ponytail in the long hair experiment I've been trying this year... I'm still not 100% sure I'm going to keep this style. This may be the first and only presentation you see with me like this.)

Unfortunately, the video only shows me talking on stage and doesn't show the slides I was using... so you don't understand what I'm talking about when I reference the slides.

I've posted the slides to my SlideShare account but as you'll see without the video or audio they aren't of much value. This was a wonderful opportunity for me to present in the very minimalist style I prefer where I only use images or a few words - and I thoroughly enjoyed doing so.

However, syncing the slides to the video is not something you'll probably find easy. At some point perhaps I'll create another video showing both my speaking and the slides... but I don't know that it will happen anytime soon.

Meanwhile, here they are...

Some of the links I reference in the presentation include (in the order of their appearance):

If you enjoyed this presentation and would like to have me potentially speak at your event, please do contact me. I've been speaking for many years and very much enjoy giving these kind of presentations at all types of events.

My First RFC - 7649 On "The Jabber Scribe Role at IETF Meetings"

Rfc7649 jabber scribe role 660px

Last month the first Request For Comments (RFC) was published where I was one of the co-authors. Ironically, this RFC 7649 had nothing to do with SIP, VoIP, telecom, IPv6, DNSSEC, security... or any of the other open Internet standards I've been working on in recent years!

In fact, it's not a "standard" at all but rather an "informational" document.

This document collects together a series of best practices for how someone can fill the role of the "jabber scribe" at IETF meetings, such as the IETF 94 meeting about to happen in Yokohama, Japan, starting this weekend. (Which I will not be attending due to scheduling challenges.) You can read RFC 7659 at:

As the abstract states:

During IETF meetings, individual volunteers often help sessions run more smoothly by relaying information back and forth between the physical meeting room and an associated textual chatroom. Such volunteers are commonly called "Jabber scribes". This document summarizes experience with the Jabber scribe role and provides some suggestions for fulfilling the role at IETF meetings.

The document came about because over the years that I've been involved with the Internet Engineering Task Force (IETF) I've come to both value the critical role the "jabber scribe" can play - and I've also tried to do the best I can to perform that role when I'm in working group sessions at IETF meetings. I typically volunteer as a jabber scribe in any of the sessions I'm in and try to make the experience as good as possible for remote participants.

Largely my interest is because I spent many IETF meetings as a remote participant and I knew how poor that experience can be.

A few years ago after one of the IETF meetings, I made a comment to a couple of people that we ought to write down some of the suggestions and best practices so that people could easily get some ideas for how they could help out in the role. If they were new to the idea... or even if they had been around but were interested in doing the role better.

I kept track of some ideas ... and a small group of us kept occasionally bouncing ideas around... but none of us had the cycles to write the actual document.

Then last year at, I think, the Toronto IETF meeting in July, Peter St. Andre and I were talking about it again - and this time we actually got it off the ground! More precisely, Peter kicked it off and then he and I went through several rounds of revisions and comments.

Given that Peter's authored 35+ RFCs and countless Internet-Drafts (I-Ds), he knows the IETF process inside and out and so was able to guide the document through the publishing process, including having it move through the "independent submission" stream of RFC documents. I've written a number of Internet-Drafts over the years, but none have yet progressed to an RFC. I learned a great bit from Peter through the process and look forward to using that knowledge in the future.

I greatly appreciate Peter's leadership on this - and I hope that this document will be helpful to many folks out there who are helping involve more people remotely in the IETF's standards process.

Given the timezone difference with Japan, I'm not sure how many of the IETF 94 working group sessions I'll actually be able to attend remotely... but if I do, I'll be hoping that whomever is acting as the Jabber scribe will help include those of us who are remote.

Meanwhile, it is kind of fun to have my name on an RFC, even if it's an Informational one. I look forward to being able to play even more of a role in the IETF standards process in the years ahead...

Keynote at AstriCon on Oct 14: Open Source And The Global Disruption Of Telecom - What Choices Will We Make?

Two weeks from today I'll be in Orlando giving the opening keynote address at AstriCon 2015. The abstract of the session is:

Open Source And The Global Disruption Of Telecom - What Choices Will We Make?

Wednesday, October 14th, 2015 - 9:00 am to 9:45 am - Pacifica Ballroom 7

There is a battle raging for the global future of telecommunications and the Internet. Taking place in networks, board rooms and legislatures, the battle will determine how we all communicate and what opportunities will exist. Will telecom support innovation? Will it be accessible to all? Will it give us the level of security and privacy we need to have the open, trusted Internet? Or will it be restricted and limited by corporate or government gatekeepers?

The rise of voice-over-IP has fundamentally disrupted the massive global telecommunications industry, infrastructure and policies. Open source software such as Asterisk has been a huge driver of that disruption and innovation.. but now what? What role do platforms such as Asterisk play in this space? And what can be their role in a telecom infrastructure that is now mobile, increasingly embedded (Internet of Things) and more and more using proprietary walled gardens of communication?

Join the Internet Society's Dan York in an exploration of what the future holds for telecom infrastructure and policy - and how the choices we make will determine that future.

Sounds great, eh?

Now I just have to deliver on that lofty rhetoric! :-)

Seriously, though, I'm very much looking forward to giving this presentation and I'm delighted that the folks at Digium asked me to speak. We're at a critical time in the evolution of our global communications infrastructure... with everything moving to IP and also moving to mobile, there are incredibly important choices we have to make for our future.

In the talk, I'll be speaking about the scenarios we have for what our future Internet could look like. I'll be talking about the role of open source. I'll be challenging the audience with some questions to ponder. I'll touch on some of the incredibly important - yet hard to understand - global policy issues such as the upcoming WSIS+10 Review in December - and why an open source developer should even remotely care! I'll of course hit on security issues and the rise of mobile... and more...

I'm excited!

I'm also excited to finally attend an AstriCon event. I used to write about Asterisk a good bit and for a while was running my own server in my home office for VoIP... but in all that time I never was able to work in attending an AstriCon!

If you are going to be there in Orlando, please do say hello! (There's still time to register!)

P.S. And yes, Olle Johansson, I'll be sure to work in at least one reference to IPv6! And TLS, too! Don't worry! :-)

Four Years At The Internet Society

ISOC geneva 400It was four years ago today that I joined the Internet Society staff... and what an amazing four years it has been!

If I go back and read my long post here about joining ISOC in September 2011, my passion and motivation continues to be the same - if anything, that passion has only gotten stronger!

As I wrote about last year in my three-year post, the "Internet of opportunity" that we all value is under severe threat.

The big change for me this past year, was, of course, the big change of joining the Internet Society Strategic Communications team in March 2015 (you can also listen to an audio recording).

That's been a wonderful yet crazy change!

If you go back and look at what I wrote last year - or two years ago - it's all about the technology behind the Internet and how we need to improve the infrastructure to make the Internet work better, be faster and be more secure.

The change this year is that now I'm more involved in other areas of Internet Society work, particularly in the public policy space. You can see that in some of the posts I've been writing for the main ISOC blog (scroll down my bio page to see the list). I've been very involved in adding content to the public policy and Internet governance sections of the website - and I've been working on our overall content strategy for a range of different websites (whereas in the past I mostly just focused on the Deploy360 site).

I've also found myself involved in projects such as standing up a web site for our Call For an Open WSIS+10 Preparatory Process... which it was only after getting it all set up that I really sat back and realized we were coordinating a coalition of organizations that was calling on action from the President of the United Nations General Assembly! Quite a different level of advocacy than I've been involved with in the past! (And still open to sigantories, by the way...)

My new role this year has given me an amazing view about all the work the Internet Society is doing around the world... it's truly inspiring to see it all.

Perhaps most inspiring is to see that the work is ultimately about helping people have better lives. Yes, technology is definitely a large part... but the work we do is about how technology enables better communication, connection, collaboration, creativity and commerce... it's the effect on people that matters most.

The new role is crazy busy... I'm definitely NOT sitting around playing Solitaire or Tetris! :-)

But we have a great team... and we as an overall organization are working on getting more focused on what activities we can do to have the biggest impact on ensuring the "Internet of opportunity" is available for all.

I'm VERY much looking forward to what the fifth year brings!

P.S. Recently Russ White published a very nice overview of the Internet Society on the PacketPushers site - and if you're interested, becoming a member of the Internet Society is free and can connect you to others around the world who want to see an open Internet available to all!

There Was Power In What Happened Last Night (At InterCommunity 2015)

Icomm15 all

There was an amazing power in what happened last night. There was a "magic" ... that I can't quite explain.

I sat in a room in Ottawa, Canada... but yet for 2.5 hours I was connected into a global meeting that brought me together with people all around the world... sitting in their homes, offices... or wherever. And gathered in large groups in New Zealand... Tunisia... El Salvador... Uruguay... New York... DC... the Dominican Republic... more...

The event was the Internet Society's InterCommunity 2015 ... something I wrote about on Circle ID, wrote about here, and talked about twice in my TDYR podcasts: episodes 258 and 259.

For that 2.5 hours we talked about how we are collectively working to bring the opportunities of the Internet to the 50% of the world that doesn't yet have access... we heard stories about the amazing work people are doing... we heard about our new 2015 Global Internet Report that highlights the rise of the "mobile Internet" and both the awesome potential - and pitfalls - that we are seeing... we talked about "Collaborative Governance" and how we need to work together to address the changes the Internet has brought to governance - and how governments adapt to the Internet... we heard from people in different parts of the world about the work they are doing... we talked about Internet security and how our "Collaborative Security" approach can be applied to activities people are doing... we had excellent questions about encryption and open vs closed systems... we talked about needing to speak in clear simple voices to explain these challenges... about the need for a stronger identity for the Internet Society... and so, so, so much more.

But it was FAR more than just the conversations... which were excellent.

It was the CONNECTION that I could feel...

Over 2,300 people registered for the event and some % of those folks were online for the first session last night...

There was power in seeing the faces of all the people around the world.

There was power in hearing the voices of the all the people around the world.

There was power in reading the text comments in the chat or on Twitter and social networks.

For that period of time... geography didn't matter... nationality didn't matter... race didn't matter... gender didn't matter...

We were just people ... connecting ON the Internet... and for the Internet.

Exploring together how we could truly bring about the "Internet of opportunity" that would be available to everyone, everywhere, and that could be trusted for our communication... our conversations... our commerce... and indeed our connections.

Talking really NOT about the technology, but rather the impacts of the Internet on our society... and on our daily lives.

It was a remarkable event.

And this was just the first session! While we in the Americas timezones were getting some sleep, another group of participants was having a second session bringing together even more people across Europe and Asia.

I woke up to see a steady stream of outstanding tweets using the #icomm15 hashtag - as well as email from colleagues and others - showing that the second session was equally amazing.

There was power in what happened last night.

The challenge now, of course, is to move what happened last night from beyond just conversation into the action that we need to truly realize the potential of the Internet.

That will be our task in the days, weeks, months and indeed years ahead...

For me, as I get ready now to make the 7-hour drive back home from Ottawa to New Hampshire, I'm still processing in my mind what it was all about. It may take some time - and reflection - to truly understand.

Yes, on one level it was "just" a meeting of different people tied in via video connections all across the Internet and streaming out to individuals via the Internet. No big deal, right? We can do this all the time, right?

But it was also something more...

There was power in what happened last night.

InterCommunity 2015 on July 7/8 - Join In To Voice Your Opinion! (And I'll Be In Ottawa)

Intercommunity2015 squareHow do we as a society address some of the most critical concerns about Internet governance? Internet security? connecting the entire world? (including all the Internet of Things?) This week on July 7 and 8 you have a unique opportunity to get involved with discussions - and actions - related to these questions at the Internet Society's InterCommunity 2015 event.

It is an event happening ON the Internet... not tied to any one physical location but rather bringing together thousands of people around the world in a global conversation.

You can register for free at:

You can join in from your home, office, or wherever you have connectivity. The meeting will be taking place in two different sessions:

  • 7 July 2015 from 20:00 to 22:30 UTC
  • 8 July 2015 from 06:00 to 08:30 UTC

(Use this time zone converter to find out what times these are for you!)

As the agenda shows, we'll have sessions on Internet access, governance and security - and a chance to interact with people on all of these issues.

Now, there are what we call "regional nodes" around the world where larger groups of people will be gathering together to have face-to-face conversations and to also join into the global conversation. If you are near one of those locations you are welcome to go to the meeting place there to meet other people in your region.

I'll actually be in Ottawa, Ontario, Canada, at the node there... if you are in Ottawa I look forward to seeing you there!

I'm very much looking forward to this meeting in part because these issues are so critical... and also because InterCommunity 2015 is an experiment in doing a global meeting across the Internet - and that is to something we need to do more of! So I'm looking forward to seeing how it all works out!

Please do join with us over the next few days and be part of this conversation!

P.S. InterCommunity 2015 is a meeting of the members of the Internet Society, but if you are not already a member (membership is free) you can join as part of the registration process.

P.P.S You can also follow the #icomm15 hashtag during the event on Twitter ( ) and other social networks.

Net Neutrality: Did We "Win" A Battle, Only To Possibly Lose The War?

FCC logo

Friends don't understand why I'm not jumping for joy after the FCC's "Network Neutrality" decision yesterday.  After all, they've been hearing me passionately argue for years about how we need to wake up and pay attention to the choices we have to make for the future of the Internet.  They've heard me rail against the Internet access providers here in the US who seek to be the new gatekeepers and require people to ask permission or pay to get new services online.  They've heard me strongly say that "The Internet Way" is for services to be "decentralized and distributed".  They've seen me write about "permissionless innovation" and the dangers we could face.  In fact, I'll be in Austin, TX, next week speaking at the NTEN conference about "Our Choice of Internet Futures"

They know that I joined the Internet Society in 2011 specifically to fight for the open Internet - and that a large goal in my life is to be one of the voices helping advocate for the open Internet and ensuring that my children have the same "Internet of opportunity" that I've been able to have.  Friends could hear in the closing words of FCC Chairman Tom Wheeler many of the same phrases and words that I have been so passionately advocating about over many years.  
Why, then, am I not dancing in the streets?
Two reasons.
1. What Is In The FCC Order? - Seemingly lost in all the media euphoria yesterday was a basic fact:
No one outside the FCC Commissioners and their staffs have seen the actual "Order" that the FCC voted on yesterday.  Sure, we've heard all the lofty rhetoric and seen the summaries... but the rumors are that the actual document is over 300 pages and full of details.
Perhaps I’m just cynical, but the telecommunications industry in the United States employs hundreds of lawyers in Washington, DC, to influence and shape legislation and regulations in ways that benefit the telecom industry - and they've been doing so for over 100 years.  And so while some of the companies may line up to file lawsuits against this FCC Order, odds are very good that their lobbyists and specialists have been hard at work attempting to shape these new regulations. I know some people at the FCC who are strong open Internet advocates and who I'm sure are trying to do the right thing... but I also know that 300+ pages has a whole lot of room for things to slip in.
My greatest fear is that when we actually see the full text, we may find that while there are some provisions we like, there are many others we don't - and there may be loopholes big enough to drive an entire residential network through.  

"The other problem with rules is that they are brittle. Teams of lawyers will comb through whatever the FCC finally publishes and find any loopholes. There will be defined bright lines going forward and, make no mistake, ISPs will now get as close to those lines as they can. Whatever the Internet's rough consensus of "acceptable" was before, it's about to be thrown out in favor of a set of rules written by lawyers. Ironically, that may end up resulting in a regulated network that is less neutral than what we have today."
2. The Internet Is Not (or WAS Not) The Telephone Network - For so many years (in fact, decades for some people), we who are advocates of the open Internet have said at every chance we could one simple fact:
The Internet is NOT the telephone network.  The Internet is NOT the PSTN (Public Switched Telephone Network).
And therefore the Internet should NOT be regulated like the traditional telecom network.  The Internet should not fall under traditional telecom legislation and regulation.  The Internet should not be regulated by the traditional telecom authorities and telecom regulators.  
You cannot apply the old rules of telecom to the new world of the Internet.
The Internet is something new.  The Internet is NOT telecom.   Again and again and again and again we've all said this.  Going back many, many years.
If you remember back to 2012 and the whole World Conference on International Telecommunication (WCIT) where so many were concerned that the International Telecommunications Union (ITU) was going to try to assert authority over the Internet, millions of us around the world rallied together to encourage our advocates in governments and organizations to say at WCIT that: 

The Internet is NOT telecom.  You cannot apply the old rules of telecom to the new world of the Internet.
And the outcome of WCIT was that the Internet was left alone and was recognized as being outside the scope of a treaty focused on telecommunications/telephony.
We all within the Internet have been saying this consisistently again and again:
The Internet is NOT telecom.  Those are old rules - we are living in a new medium.
But guess what?  
Yesterday's ruling by the FCC says (as best we understand it) - the Internet does fall under telecommunication regulations.  Internet service providers should be classified under Title II just like all the other telecommunications service providers.
The FCC has effectively said: 
The Internet IS telecom.  The old rules DO apply.
I am not sure that is something to celebrate.
Many countries around the world have followed the lead of the US in treating the Internet lightly - but now that the FCC is effectively declaring the Internet to be like the telephone network, what is to stop those countries from doing the same?  Indeed what is to prevent the ITU from now using this action to justify a larger role for it in regulating the Internet?  After all, it's just telecom now.
I would have personally been far happier if the U.S. Congress had come up with new legislation that enshrined the principles of the open Internet in a new form  of legislation that didn't carry with it all the legacy baggage of 100 years of telecom regulation. Yes, the legions of lawyers might have made it a hard fight, but it would have at least been something new - and at least we would have known more of what was actually being voted on. But that didn't happen - and so here we are today.
The "devil is in the details", as they say... and now we have to wait to see what exactly the FCC actually did yesterday.  I'd like to be wrong and just be cynical and jaded.  I fear that I am right.
I applaud FCC Chairman Wheeler for the lofty language he and the other commissioners used yesterday.  It is a huge victory to have the heads of the FCC saying publicly so many of the things that so many of us have been advocating about for so many years.  It is also a huge victory to have so many millions of people, not just in the US but all around the world, rise up and pay attention to these issues as a result of this whole issue here in the U.S. That is HUGE.  We've needed something like this to wake people up to the choices we have to make.
But I do worry that in "winning" this victory yesterday, we may in fact be setting ourselves up to lose the larger war to keep the Internet open.

Video: VUC 528 Provides An Update On And Wire

Vuc logoLast Friday's VUC conference call / podcast / hangout provided some interesting updates about the ongoing work at to build services for scalable, distributed and federated collaboration systems as well as some discussion of Wire, the app I've written about here. Guests included Matthew Hodgson and Amandine Le Pape from, as well as the usual cast of characters and a couple of live demonstrations, too.

You can view the episode web page and listen to the show here:

I joined the show about mid-way through and naturally wound up talking about IPv6, the Internet of Things (IoT), ICANN, DNS and other topics.

FYI, some good info about can be found in their FAQ. Back in November 2014, there was also another VUC episode focused around

It was an enjoyable show and I'd encourage you to give it a listen.

Join Me On VUC Today At Noon US EDT To Talk IPv6, IoT, WebRTC and more...

Today at 12 noon US Eastern (in about 3.5 hours), I'll be part of a panel on the VoIP Users Conference (VUC) talking about IPv6, WebRTC, the Internet of Things (IoT) and much, much more... you should be able to watch it live at or embedded here:

VUC host Randy Resnick had a scheduled guest be unable to attend and so he asked a group of us to come on for what he is calling a "VUC Vision" session. I will be on there, as will, I believe, Tim Panton and a number of others. I expect the discussion should range over good variety of topics. It should be a good time... you're welcome to join in the discussion.

It's probably best to also join the IRC backchannel where links are shared, questions are answered and other comments occur. You also can visit the Google+ event page for the VUC session today where there may be additional links and info.

If you won't be at your computer, you can also call in via:

Talko Looks Very Cool, But Needed A Firewall Change To Work

Talko directoryThe big telecom story today certainly seems to the be launch of Ray Ozzie's new "Talko" application for iOS. Tons of attention in the tech media, and many of my friends on social media have been trying it out. There's a brilliant article posted on Medium about the "Brave New Phone Call" along with a great blog post from Ray Ozzie about how this new app will revolutionize the voice experience.

I think Talko has great potential to do so, particularly after using it.


... I had to change my firewall rules in order to make Talko work. :-(

And I don't know how long it will continue to work.

Perhaps worse than that... it wasn't clear initially that I had a firewall problem. Frequent testing partner Jim Courtney sent me a message and after installing the Talko app on my iPhone I tried to talk to him, but all I seemed to be able to do was send him a voice message or a text message.

Subsequently I tried connecting to Tim Panton and again could only send voice messages. It made for a very asynchronous "walkie-talkie" style of communication that clearly seemed to not be what was described in the article.

At that point my many years in VoIP kicked in and I realized the firewall at the edge of my network was probably blocking something. Sure enough, when I pulled up the live firewall log and filtered on my iPhone's IP address I could see blocked connections from my iPhone that were intended for an IP address in Amazon's EC2 cloud. These blocked connections happened when I tried to initiate a voice conversation within Talko.

I first tried to create a firewall rule that would allow specific ports through, just by guessing from the firewall logs what ports Talko might be using. However, they jumped around and what I ultimately had to do was create a rule allowing any connection from inside my network to the specific IPv4 address of what I assume is one of Talko's servers on Amazon EC2.

Once I did this, I was able to have a voice conversation with Tim perfectly fine. It was actually rather cool how it would record the conversation and let me easily go back, listen again, advance through it, etc.


... poking a hole in my firewall to a specific IP address is very definitely NOT the way to have a telecom application work.

And... Talko will only work on my network as long as that destination IP address doesn't change. If they add more servers or change their architecture, it's dead to me. At least... dead on my home WiFi network. Presumably it could still work on my mobile data network (at a cost to me).

Now, to be fair, I'm a bit more security-paranoid than the average home user and so I run a Linux-based firewall/server/gateway on the edge of my home network with a fairly restrictive set of firewall rules. The default policy is to deny outbound connections unless they fit into various rules. I've had to add rules allowing VoIP and IM protocols... and it's not uncommon for me to have to add new rules for applications like this. For instance, I had to do so for Tox when I was playing with it a few months back.

Odds are Talko will probably work fine for the vast majority of connections from WiFi networks with less paranoid firewall rules.

But... for an app like this to really challenge the existing telecom infrastructure, it needs to work from almost anywhere. This is why Skype usage is so ubiquitous - Skype "just works" and has its ways to work around firewalls. Within the SIP and WebRTC communities there are all the STUN / TURN / ICE servers and technologies that enable this kind of transit of a firewall. The technology is out there. And there will certainly be some enterprises and other businesses that set up firewalls at least as restrictive as mine is.

I realize today's news is the initial public launch and that this is early days for the app. I hope the Talko team can figure out a way to make the voice conversation work through firewalls. I really like what I see inside the app.

Meanwhile... I'm just hoping they don't change the IP address of the server with which my app is communicating!
