Last Day To Submit Speaking Proposals for SIPNOC2013

Sipnoc 2013Got a great idea for a talk to give to an excellent gathering of SIP/VoIP network operators? Have a new way of handling security? Have a case study you'd like to present for how you solved an operational issue?

The SIP Network Operators Conference (SIPNOC) is an outstanding event happening in Herndon, Virginia, USA, from April 22-25. It brings together network operators working with SIP / VoIP networks for several days of talks, networking (of the human kind) and education. I've gone the past two years, speaking about IPv6, and they are truly excellent conferences. Not too big, not too small... and with an extremely high quality of people both attending and speaking.

If you think you'd like to present, TODAY, January 25, 2013, is the end of the call for presentations for SIPNOC 2013. They are seeking presentations on topics such as (see the CFP for more detail):

  • Peering
  • SIP Trunking
  • Congestion Control
  • Applications/content Development
  • Interoperability
  • Call Routing
  • Security
  • Monitoring/Troubleshoooting and Operational Issues
  • Testing Considerations and Tools
  • Availability/Disaster-Recovery
  • WebRTC and SIP
  • SIP-Network Operations Center Best Practices
  • Standardization Issues and Progress
  • FoIP/T.38 Deployment
  • User-Agent Configuration
  • IPv6 Deployment Challenges
  • Emergency Services
  • Scaling and Capacity Issues
  • HD-Voice Deployment Challenges
  • Video Interop Issues

They are seeking individual talks, panel sessions, research sessions and BOFs.

Even if you just have an idea for a session, I'd encourage you to submit a proposal so that the SIPNOC 2013 Program Committee will know of your interest and can reach out to you for more details. More info about the process can be found on the CFP page.

If you aren't interested in speaking, but are now intrigued by SIPNOC and would like to be learning from all the excellent sessions, you can go to the SIPNOC 2013 main page and find out information about how to register and attend.

If you work at or for a telecom/network operator who is involved with SIP and VoIP, I highly recommend SIPNOC as a conference you should attend - you'll learn a huge amount and make great connections.

P.S. I have no affiliation with SIPNOC other than being a speaker there in the past. SIPNOC is a production of the SIP Forum, a great group of people focused on advancing the deployment and interoperability of communications products and services based on SIP.

T-Mobile Rolling Out HD Voice (Wideband) In US Mobile Network

T mobileMarking a huge step toward moving beyond the limitations of the legacy phone networks, at the Consumer Electronics Show (CES) this week in Las Vegas T-Mobile announced that HD Voice is now available nationwide on its US network. This will give people the richer, fuller voice experience similar to what many of us have gotten used to experiencing while making Skype calls.

There is, of course, the caveat that HD voice (also called "wideband audio") is only available using specific smartphones:

To experience HD Voice, both parties on the call must use capable T-Mobile 4G smartphones such as the HTC One™ S, Nokia Astound and Samsung Galaxy S® III

TheNextWeb also suggests that the iPhone 5 should support HD Voice when T-Mobile makes it available on their network sometime this year.

Over on AnandTech, Brian Klug dives into a bit more detail about T-Mobile's HD Voice, specifically naming the AMR-WB codec, and relays some of his own testing that confirmed that it is live now.

This is an excellent step forward, even with the caveat that it only works on T-Mobile's 4G network and only with specific smartphones. As more and more people get used to the richer and better quality of wideband audio, expectations will rise and continue to push the ongoing migration of all telecom over to IP-based solutions.

Kudos to the technical teams at T-Mobile for making this happen!

P.S. I'm also personally pleased to learn about this because T-Mobile supports IPv6 across their mobile network, too. Now if only they could improve their coverage in southwestern New Hampshire, I'd be able to actually consider switching to them.

World Conference on International Telecommunications (WCIT) Starts Today in Dubai

WcitToday is the start of the International Telecommunication Union's (ITU) World Conference on International Telecommunications (WCIT) in Dubai. The aim of the conference is to update the "International Telecommunications Regulations (ITRs)", a treaty between nations that establishes rules for interoperability and interconnection for telecom between countries.

These ITRs were last updated in 1988... and the world of telecom has changed just a wee bit since then! :-)

Unless you've been asleep or offline for the past few months, you'll know that some of the countries out there are seeking to use this WCIT conference as a way to expand the ITRs to cover the Internet - and to thereby control the Internet more or to impose other business models on the Internet. Obviously a lot of people (myself included) are opposed to the expansion of the ITRs to include more of the Internet and believe that the ITRs should remain focused on the telecommunications interconnection related to the traditional Public Switched Telephone Network (PSTN).

This all will play out over the next two weeks in the meetings happening in Dubai that will culminate with a series of votes by the member states. The ITU is a United Nations (UN) entity and so each country gets a vote.

I'll not comment further here about the ITRs and WCIT, except to note that if you want to follow along with what is happening, my colleagues in the Internet Society Public Policy team (of which I am not a part) have been maintaining a site where they are curating news about WCIT:

http://www.scoop.it/t/wcit

They've been doing a great job and it's the site that I am using to keep up with what is being said out there about WCIT and the ITU.

That same team also has a great site full of background material about WCIT, the ITRs and other related information - follow the links in the right sidebar for much more material:

http://www.internetsociety.org/wcit/

The material includes a good background paper on the ITRs that explain a bit about how the ITRs evolved and why they matter. The Internet Society's communications team also has a page up that they will be updating throughout the week with news:

http://www.internetsociety.org/wcit-newsroom

You can expect to see social networks filling up with commentary, too... and I know I'll be watching two Twitter hashtags:

The reality is that true to the title of this blog, the telecommunications industry has been severely disrupted by the Internet. The world of the PSTN has been fundamentally altered by Voice over IP (VoIP), by "Over The Top" (OTT) applications, by SIP trunking... and so many other aspects of Internet-based communications. This WCIT event does provide a chance for all of those who have been victims of this disruption to try to push for changes that will be in their favor. Similarly, all of those wanting to ensure the Internet remains open are fully engaged now, too... and various countries are aligning on both sides.

It shall be an interesting next two weeks...

P.S. Vint Cerf's op-ed on CNN is worth a read on this topic: 'Father of the internet': Why we must fight for its freedom

Ameche Lets Telcos Add Apps Into Regular Phone Calls To Add Value And Services

AmecheImagine you are driving fast along a major highway in traffic and you receive a call from a critical customer. She wants to know immediately when you can meet tomorrow with her team to go over the final proposal and sign the deal. There's no way for you to pull over and look at your calendar on your phone or computer... and it's really not safe in the high-speed traffic for you to be flipping through your calendar while you talk. What do you do?

Do you tell her you'll give her a call back when you get to a safe place? Or do you do the unsafe action of looking at your calendar on your phone?

What if there was a different way?

What if you could say something like "Let me check my calendar for tomorrow at 3pm" and then suddenly have a voice whisper back to you - on your call, but only heard by you - "your calendar is free at 3pm. You have meetings at 2 and 5."

You could then reply to your customer after just this brief pause letting her know that you could meet with her.

Sound like science fiction?

Perhaps... but that is the type of functionality that the team over at Voxeo Labs is looking to bring to calls with the launch of their new cloud service offering called Ameche. They are using the tagline "Apps in your Calls™" and produced this brief video to talk about what can be done:

I admit that I find their overview page and their introductory blog post a little bit over-the-top in terms of marketing-speak, but it starts to get interesting to me when you look at the page about apps in your calls. I'm not sure that I personally would get too excited about the "Social Calls Status Updates" example but it is extremely cool and valuable that they have this capability to connect with social networks. I find the other use cases such as Salesforce.com integration and context-based routing, and including the case I described at the beginning, far more compelling. It's also very important to note, as they do farther down that page, that Ameche is a platform and so can be used to build many different types of applications:

Ameche possibilities

That platform itself, described on the Ameche technology page, sounds quite intriguing. As I understand it, they are essentially deploying a virtual machine running Node.js into a carriers network and then deploying applications inside that VM. They provide this network diagram showing how the pieces can fit together:

Ameche technology

The outstanding part here is that they are using common web programming languages and fitting directly into existing carrier networks. This platform will let telcos create new services that can work with existing phone connections and existing phone numbers. No need for the customer to do anything except order the new service. No apps to download, no numbers to configure.

Obviously the primary market for this service is really the telecommunications service providers / carriers who are looking to offer additional services to their customers. At a time when those telcos are so threatened by the rise of various VoIP services and are looking for ways to build customer loyalty and keep the customers from leaving, Voxeo Labs' Ameche may just be the type of platform those carriers need right now.

Congrats to the team at Voxeo Labs on this launch - and I look forward to seeing what telcos will build with this new platform!

Full disclosure: I worked at Voxeo for 4 years and as a result am a small shareholder in the company. However, I would not write about the company or its products unless I thought they were worth writing about.

Hypervoice – The Fundamental Flaw In The Proposal

MartingeddesI am a huge fan of Martin Geddes, but he and I disagree fundamentally on one key part of what he is now calling "hypervoice".
NOTE: Today's VUC call at 12noon US Eastern will be with Martin discussing his ideas. If you'd like to weigh in on the issue, please join the call. (Unfortunately, I'll be waiting to board a plane home from Mumbai and can't make it... hence this blog post.)

To back up a bit, Martin has always been one of the "big thinkers" in realm of VoIP and telephony/telecom. Way back in mid-2000s when a number of us all started writing about VoIP, Martin's Telepocalypse blog was brilliant. He was always thinking about the "big picture" and drawing connections where they were not already apparent. His work with "Telco 2.0" was excellent and it was no surprise when he went to work for BT looking at their strategy. Now that he is back out on his own as a consultant, I'm a subscriber to his "Future of Communications" email newsletter (subscribe on the sidebar to his site) and enjoy reading his frequent issues.

Recently he gave a closing keynote presentation at the Metaswitch Forum titled "A presentation about Hypervoice" that is available via Slideshare or PDF.

The presentation itself is very well done. In typical Martin style it nicely lays out the history of both telecom and the web and brings them together to talk about what comes next.

I actually agree with almost all of what Martin writes. Much of what he talks about as "hypervoice" I see already happening in so many ways.

But here is where we fundamentally disagree... this slide early on:

Hypervoiceflaw

That includes the text:

"However, the Internet cannot and never will carry society's real-time communications needs. It is fundamentally unsuited to the job."

Martin's argument, which he has made multiple times before, including in a comment he wrote in response to my post about how WebRTC will disrupt real-time communications, is that the Internet as it exists today cannot provide the level of service that is truly needed for real-time communications. He believes we need to have different classes of service on the Internet and separate "flows" of communications. He comes back to this point later in his "Hypervoice" slide deck:

Hypervoice polyservicenetworks 1

This is where he and I part ways. As I said in my own response to Martin's comment to my earlier post:

Martin, yes, I've read your newsletters on this point and while I understand the concern I'm not ready to say that the plain old Internet can't deal with the contention. Back in the early 2000's I was the product manager for Mitel's "remote teleworker" product and there was great concern from the traditional telecom folks within Mitel about this idea that we were going to put an IP phone out at some random point on the Internet where there was no QoS or anything. In fact, some folks wanted us to say that it had "cell-phone voice quality" so that we wouldn't set high expectations about voice quality. The reality was that through appropriate codecs, jitter buffers and other technologies the connections almost always worked and almost always had outstanding quality (usually FAR better than cellphones).

The other reality is that we've seen OTT providers like Skype and others providing excellent services that work the vast majority of the time. We're seeing new and improved codecs coming into the market. We're seeing new traffic shaping technologies. The list goes on...

If the (brief) history of the Internet has shown us anything, it is that the Internet's capacity to adapt and change is boundless. We'll see what happens in the time ahead.

And no, I haven't written off the telcos as having a role in real-time comms. I just don't know that the "role" they may have will necessarily be the one they would like to have! ;-)

I believe fundamentally that the "open" Internet can and will adapt to the needs of carrying real-time communications. I would argue that it already has in so many ways... and it will change even more as we continue to move more and more real-time comms onto the Internet, particularly with WebRTC and other emerging technology.

And yes, you might expect me to say this as a passionate advocate for an open Internet, but I firmly believe this:

We do NOT need separate layers of the Internet based on class of service.

That, to me, is a dangerous path. I want to continue to see an Internet where all nodes are treated equally ... and where real-time communications can work for all.

Martin and I will probably have to agree to disagree on this. It's doubtful he can convince me nor I can convince him.

What do you think? Do we need different layers of the Internet? Or can the Internet adapt without that? Leave a comment here... or join in to today's VUC call and comment there.

Slides: How The Hidden Secret of TCP/IP Affects Real-time Communications

Recently at Voip2day + ElastixWorld in Madrid 2012, Olle E Johansson gave a great presentation outlining where we are at with telecom and VoIP in 2012 - and where we need to go! Olle is a long-time, passionate and tireless advocate for the open Internet, IPv6, SIP and standards and interoperability. I've known Olle for years via Asterisk-related issues, via the VUC calls and via work on SIP over IPv6.

This presentation (slides available) really hits a number of key points about where we are at now:

In particular I was struck by his slides 24-28 that strike the same theme I've been writing about across multiple blogs, namely the way we are reversing the "open Internet" trend and retreating back inside walled gardens of messaging:

This is what customers wanted to avoid

He goes on to walk through what happened with SIP and how the protocol evolved - and evolved away from interoperability. His conclusion is that we as customers need to take back control, avoid vendor lock-in and demand interoperability.

He also points people over to his "SIP 2012" effort where he is undertaking to compile a list of what really defines "SIP" in 2012, i.e. more than just RFC 3261. (I'll note he's looking for feedback on these ideas.)

All in all an excellent presentation... and yes indeed we all collectively do need to "WAKE UP" and demand better solutions!

How WebRTC Will Fundamentally Disrupt Telecom (And Change The Internet)

Old phoneIf we step back to before 1993, publishing and finding content on the Internet was a somewhat obscure, geeky thing that a very few people cared about and very few knew how to do. It involved gopher servers, ftp sites, archie, veronica, WAIS, USENET newsgroups, etc., and this "World-Wide Web" service primarily demonstrated via the server at info.cern.ch. It was an amazing period of time for those of us who were there, but the number of users was quite small.

Then NCSA released Mosaic in 1993 ... and suddenly everything changed.

Anyone could create a web page that "regular" people could see on their computers. Anyone could download Mosaic and use it. Anyone could share their sites with the installation of server software.

The Web was truly born into public consciousness... the creation of Web-based content was democratized so that anyone could do it... the creativity of developers was unleashed... a zillion new business models were thought of... and the Internet fundamentally changed.

Fast-forward to today...

... and the "Web" is still predominantly a document-based system. You make HTTP queries to retrieve pages and send HTML and XML documents back and forth between web browsers and web servers.

Separately, we have a world of telecommunication apps that have moved to IP. These are not just voice, but they are also video, instant messaging, data-sharing. They have moved so far beyond what we traditionally think of as "telecommunications". The apps use wideband audio, HD video, white boarding, sharing and so many capabilities that cannot have even been remotely imagined by the creators of the PSTN and all the legacy telcos and carriers. They are "rich communications" applications that have severely disrupted the traditional telco world.

The problem is that creating those rich, real-time communications apps is somewhat of a black art.

It is the realm of "telephony developers" or "VoIP developers" who can understand the traditional world of telcos and can interpret the seven zillion RFCs of SIP (as all the traditional telcos have glommed all sorts of legacy PSTN baggage onto what started out as a simple idea).

Deploying those rich communication apps also involves the step of getting the application into the hands of users. They have to download an application binary - or install a Flash app or Java plugin into their browser. Or on a mobile device install an app onto their mobile smartphone.

The world of rich communication experiences is held back by development problems and deployment problems.

Enter WebRTC/RTCWEB

Suddenly, any web developer can code something as easy as this into their web page: 

------
$.phono({   
   onReady:   function()   {
       this.phone.dial("sip:9991443046@sip.example.net")
 } } );
------

Boom... they have a button on their web page that someone can click and initiate a communications session ... in ANY web browser. [1 - this is not pure "WebRTC" code... see my footnote below.]

Using JavaScript, that pretty much every web developer knows... and using the web browsers that everyone is using.

And without any kind of Flash or Java plugins.

Boom... no more development problems. Boom... no more deployment problems. [2]

WebRTC is about baking rich, real-time communications into the fabric of the Web and the Internet so that millions of new business models can emerge and millions of new applications can be born.

It is about unleashing the creativity and talent of the zillions of web developers out there and turning the "Web" into more than just a document-based model but instead into a rich communications vehicle. It's about moving these apps from an obscure art into a commonplace occurrence.

We really have absolutely no idea what will happen...

... when we make it as simple for ANY developer to create a rich, real-time communications experience as it is to create a web page.

But we're about to find out... and done right it will fundamentally change the Internet again.

If we think the legacy telco crowd are upset now about how "VoIP" has screwed them over (from their point of view), they haven't seen anything yet. WebRTC/RTCWEB doesn't need any of their legacy models. It bypasses all of that in ways that only the Internet enables. It is NOT shackled to any legacy infrastructure - it can use new peer-to-peer models as well as more traditional models. And it goes so far beyond what we think of as "communication" today. [3]

I see it as the next stage of the evolution of the Internet, disrupting to an even greater degree the business models of today and changing yet again how we all communicate. The Internet will become even more critical to our lives in ways we can't even really imagine.

THAT is why RTCWEB (in the IETF) and WebRTC (in W3C) are so critically important ... and so important to get deployed.

[1] The code I'm showing is for a library, "Phono", that in fact will sit on top of the WebRTC/RTCWEB protocols. It is an example of the new apps and business models that will emerge in that it makes it simple for JavaScript developers to create these apps. Underneath, it will use the rich communications protocols of WebRTC/RTCWEB. Someone else will come up with other ways to do this in JavaScript... or python... or ruby... or whatever language. But because they will all use the WebRTC/RTCWEB protocols, they will interoperate... and work in any browser.

In full disclosure I should also note that Phono is a service of Voxeo, my previous employer.

[2] And BOOM... there go the heads exploding within the legacy telco crowd when they start to fully understand how badly the Internet has rendered them even MORE irrelevant!

[3] Note that a WebRTC app certainly can communicate with the traditional PSTN or other legacy systems. My point is that it is not required to do so. One usage of WebRTC will, I'm sure, be to "web-enable" many VoIP systems (ex. IP-PBXs) and services. But other uses will emerge that are not connected at all to the PSTN or any legacy systems.

Skype Releases Photo-Sharing for iPhone/iPad – Trying to Disrupt MMS? iMessage?

Today Skype launched an attack on sending photos via Apple's iMessage, via email or via traditional SMS/MMS with the release of photo sharing for the iPhone and iPad versions of Skype. The key point of the blog post to me is this:

There's no limit on the size of the file you can send, so you can send photos without reaching email size limits or paying expensive MMS charges.

This is yet another example of Skype seeking to disrupt the traditional telecom industry as an "over-the-top (OTT)" app - and make the user experience that much easier. (And yes, I am fully aware that Skype for Android has had file sharing since December 2011.)

Skype's blog post doesn't directly mention Apple's iMessage, but that's the reality of what else will be disrupted. Think about it... here is what you have for options inside the built-in "Photos" capability of an iPhone:

Iphone photos

You can either email the photo or use the "Message" which goes either through the traditional SMS/MMS route - or via iMessage. This Skype functionality replaces both of those capabilities... although you need to be in the Skype application to use the sharing. Note that for a reason I'll explain later, Skype's photo sharing does NOT replace what you can share with Twitter.

Using Photo Sharing on an iPhone

I'll admit that I didn't find the sharing of the photo immediately intuitive on the iPhone, largely because Skype overloaded the "phone" icon in the upper right corner to do more than just initiate a call. In the new version, after you enter a chat with someone and tap the phone icon, you get a menu where you can share the photo:

Iphone send photo 1

After choosing to send a photo, you then can choose to take a new photo or share an existing photo:

Iphone send photo 2

The recipient then needs to accept the photo transfer, after which you see an indicator bar showing the progress - and then the fact that the photo was transferred:

Iphone send photo 3 1 Iphone send photo 4 2

From a recipient point of view, receiving the photo is simply a matter of watching the blue progress bar and then seeing the photo displayed:

Iphone send photo 5 Iphone send photo 6

I'll note that it displays nicely in a landscape view as well, although the photo is actually displayed larger in the portrait view:

Iphone send photo 7

All in all a fairly straightforward experience and I thank my friend Dean Elwood for helping me test this out. The re-use of the "phone" icon is a bit strange - and non-intuitive - but once you get used to that it's okay.

Using Photo Sharing on an iPad

Photo sharing on the iPad was very similar, with the added benefit that the icon in the upper right was the much more intuitive "+" symbol. Again, when in a chat with someone you just touch the "+" and choose "Send Photo":

Ipad send photo 1

You again have the choice to take a photo or use an existing photo:

Ipad send photo 2

After which the photo nicely appears within the Skype client:

Ipad send photo 3

Again, a rather straightforward and easy user experience.

The Desktop Disconnect

While this works great for sending photos between iOS devices (and I will assume to Android devices), the user of the traditional Skype desktop app does not have such a seamless experience. Here is what happened when I accepted a photo from Dean in the latest Skype for Mac version:

Send photo desktop

I then had to double-click the icon to open the image in the separate "Preview" application on my Mac. It would be great if in some future version of the desktop version of Skype the images would be displayed inline as they are on the mobile versions.

The Android Difference

It's also interesting to note that Skype for Android lets you share any kind of files, beyond just photos. As noted in the Skype for Android FAQ:

You can send and receive any type of file over Skype for Android and can view any file you receive as long as you have the necessary software or application installed. There are no limits on the size of the file you can send. As long as the person you’re sending the file to has enough memory on their phone, they can store the file.

Several mobile developer friends have indicated that this is due to the difference in the mobile operating systems and the fact that Android gives developers access to more file capabilities than does iOS. Still, it's just an interesting difference between the platforms.

Not Displacing Facebook / Instagram / Google+ / Twitter / etc.

My initial thought on seeing Skype's blog post was that Skype was going to try to take on photo sharing services like Facebook, Instagram, Google+ or even Twitter. It became rapidly clear that this photo sharing service is NOT attempting to do that (yet, anyway). A couple of reasons:

1. It only works with 1-to-1 chats. You can only get that "Send Photo" button when you are in a direct, 1-to-1 chat with another Skype user. When you are in a group chat, there is no way to share a photo. If there was, you could start using groups as a way to share photos... but that capability isn't there.

2. There is no web access for photos. When you share a photo there is no URL you could give someone else to see the photo. The photo does not appear to be stored on any server anywhere. Rather it is simply transferred from one local Skype client to another local Skype client.

3. Both Skype clients must be online. The sender and recipient both have to be online for the photo to be transferred. This is true of all Skype file transfers and photos are no different.

For the moment this seems all about sharing a photo with someone else with whom you are conversing.

So Who Will Use This Photo Sharing in Skype?

But will people actually use this new feature? After all, Skype's blog post today refers to this as "a frequently requested feature." (Although without any details about by whom it was requested.)

I'm going to guess that Skype's proverbial use case is that you were out during the day, took some photos, and then some time later are in a voice or video call with someone and want to share the photos of what you did earlier. It's the old "Look, Grandma, here are some great photos of us at the amusement park!"

Or maybe you came back from a trip and want to share some photos with someone you call... or maybe you are in the midst of a trip and want to call home and share the photos. ("Hey, Dan, just calling you from our hotel in Rome. Look at all the cool cathedrals we saw over the last few days!")

I could see that usage... subject to my caveat below.

The Battery Problem

Skype's blog post shows the case of a young woman sending a photo to a friend of some new shoes she found. As compelling as this might be...

... I would never use Skype this way!

Or at least... I haven't yet.

Why not?

Skype for iOS drains the battery rather quickly!

For that reason I never leave Skype running on either my iPad or iPhone. I do use Skype while traveling, but it's a case of firing up Skype, making the call and then killing off Skype on the iOS device so that the batteries will last longer.

Instead for sharing photos I would simply send off the photo via Apple's iMessage... or email the photo to someone.

Now, in Skype's post today, they indicate that this new release for iOS includes performance improvements that will help with battery life:

We've also improved the overall performance of Skype's mobile apps. We've made them less battery hungry when running in the background, so you'll now be able to answer Skype calls throughout the day when they come in. And, as you'll be able to keep Skype open, you can respond to or send IMs to friends and colleagues all day long.

That, to me, will be the key for the usage and adoption of this photo sharing. I need to be comfortable leaving Skype running on my iOS devices - and so do my recipients. If we all get to the point where Skype is just "always on" on our iOS (and Android) devices... then yes, we might start using this as a way to share photos.

Undoubtedly that is how Skype / Microsoft would like the scenario to play out... we'll have to see how indeed that does work out.

What do you think? Will you use this photo sharing within Skype for the iPhone or iPad? Or will you use one of the other ways to share photos within iOS?

UPDATE, 22 Aug 2012 - Jim Courtney published a piece with his views: Skype Photo Sharing: A Conversation Feature – Not an App

What is an Over-The-Top (OTT) Application or Service? – A Brief Explanation

OttWhat is an "over-the-top" or "OTT" application or service? How does an OTT telecommunications or media app/service differ from a "regular" application?

The answer depends upon your perspective.

For a regular user of the Internet, an "OTT app or service" is something like:

  • YouTube, Hulu, Netflix or Apple TV for streaming video
  • Skype or Facetime for voice/video calls
  • WhatsApp or iMessage for messages on a mobile device
  • Xbox 360 or World of Warcraft for gaming

Basically, any service you are receiving over the Internet that is NOT provided directly by your Internet Service Provider (ISP).

Of course, for an ISP / telecommunication provider, the critical point about an OTT app/service is the part I emphasized - it is NOT a service you are paying them for.

And they are not happy about this.

It's not clear to me when precisely we in the industry started talking about "over-the-top" applications and services, but I first saw OTT mentioned back in 2008 or 2009 when the term was primarily applied to video services such as those coming from Netflix or Hulu. At the time, major US service providers such as Comcast and AT&T were rolling out their video-on-demand services and were being challenged by these "OTT" providers. Netflix and Hulu provided their service "over-the-top" of your Internet connection, without any interaction whatsoever with your Internet service provider (nor any revenue to that service provider).

Since that time, I've seen "OTT" applied to the zillions of messaging apps that have now sprouted up in the mobile environment to provide an alternative to the costly SMS provided by the traditional telcos. WhatsApp, Apple's iMessage, Blackberry Messenger (BBM), TU Me... and a hundred others that keep popping up on a weekly basis. Some would even lump Twitter and Facebook into this category. (And SMS revenue by telcos are facing a serious decline from the use of these apps. Ovum estimated the decline at $13.9 billon for 2011.)

I've also seen "OTT" applied to VoIP apps such as Skype (whose network overlay architecture I wrote about previously). And now we have Apple's Facetime and a hundred startups like Viber, Voxer, Tango, etc.

Recently I saw a document that painted "OTT" even more broadly as a term applying to any "content provider" on the Internet, i.e. basically everyone publishing content in any form.

The key point of all of this is that the OTT apps/services do not come from the traditional telcos or Internet service providers.

The telcos and ISPs are merely providers of the IP connectivity. The OTT apps ride on top of that Internet connection.

The telcos and ISPs are simply big, fat, dumb pipes.

Some of the telcos and ISPs out there are smart enough to see what's going on and are trying to become the biggest, fattest pipe out there and provide the best possible service. Some are launching their own OTT apps/service that are NOT limited to their own customer base.

And some of the telcos are so desperate to hold on to their legacy business models that they are trying to get the International Telecommunication Union (ITU) to regulate OTT apps and service providers through the upcoming World Conference on International Telecommunications (WCIT). They are hoping to use WCIT as a vehicle to re-inject themselves into the revenue stream and somehow start charging "OTT" providers. (But that's a topic for another blog post...)

So when you hear people talking about "OTT apps" or "OTT services," they are typically referring to applications or services that ride on top of your Internet connection - but have no relationship with the provider of your Internet connection.

OTT apps and services are a major component of the ongoing war between "content providers" and "access providers"... a fundamental tension within the Internet that shows no sign of being resolved anytime soon. But more on that another time... :-)

SegTEL/TVC Stringing Fiber Through Keene, NH – A New Internet Choice?

Segtel fiberWhen I look out my office window and see a bucket truck driving by with a guy up in the bucket attaching what looks like fiber optic cable to the polls, my reaction as a networking geek was naturally:
  • who is stringing new fiber?

Followed, of course, by "that's kind of a cool way to ride around town" (probably literally cool, today).

My initial thought was that it was upgraded wiring from either Fair Point Communications, our local phone company (who bought out Verizon's landline business up "he-ah"), or Time Warner Cable, who owns the cable franchise for Keene, NH.

It turned out to be neither, but rather someone new.

I walked out and met the crew up the street when they happened to be reloading connectors into the bucket. One of them said this was new service for "SegTEL". He said SegTel was a private company who had been recently bought out by someone and was planning to provide high-speed Internet access to businesses.

As I walked back to my house, my immediate reactions were:

  • Cool! Will there be a plan I can afford as an individual?
  • Will they offer IPv6?

To my surprise, SegTEL appears to have no functioning website! I did find that it has been acquired by Tech Valley Communications in New York, whose announcement of the acquisition completion in January included this bit:

segTEL was founded in 1998 and provides fiber optic telecommunication services to carrier, wholesale, and large enterprise customers throughout New Hampshire, Vermont, Massachusetts and Maine. segTEL has unique and extensive expertise in providing customized fiber optic loop, backhaul and transport services to Top-25 wireline and wireless carriers. All segTEL staff will continue their current operational activities with the combined company.

SegTEL was/is apparently located in Enfield/Lebanon, NH, about an hour north of me. In reading through TVC's news page it seems TVC received a substantial private equity investment in 2010 that made all of this possible. A Business Review article adds a bit more context to the acquisition. They also have some interesting links on the TVC news page about the growth of fiber.

An NTIA document refers to 10Gbps and 1Gbps Ethernet offerings (I'd take it!) and an FCC document from September confirms the transfer to TVC. It seems, though, that SegTEL and TVC both have been primarily targeting other service providers and large enterprises, not individuals. (Which does make me wonder why they were stringing the fiber through our very residential neighborhood.)

Sooo... given that a big fat fiber cable is connected to a pole that is literally about 25 feet away from my server, will I be able to play with a big pipe? Or will it be priced out of my range? (Probably!) And, important to my role, will it support IPv6?

And SegTEL or TVC folks, should you read this... you've got a willing beta tester for your new service offering! ;-)
