The Directory Dilemma - Why Facebook, Google and Skype May Win the Mobile App War

As much as I am enjoying the new Wire app, there is a fundamental dilemma that Wire faces... as well as Talko, Firefox Hello, Subrosa and every other Over-The-Top (OTT) or WebRTC application that is seeking to become THE way that we communicate via voice, chat and/or video from our mobile phones and desktops. That is: How do they gather the "directory" of people that others want to talk to? more

Has the FCC Created a Stone Too Heavy for It to Lift?

After five years of bickering, the FCC passed an Open Internet Report & Order on a partisan 3-2 vote this week. The order is meant to guarantee that the Internet of the future will be just as free and open as the Internet of the past. Its success depends on how fast the Commission can transform itself from an old school telecom regulator wired to resist change into an innovation stimulator embracing opportunity. One thing we can be sure about is that the order hasn't tamped down the hyperbole that's fueled the fight to control the Internet's constituent parts for all these years. more

Taking Aim at 8 Myths about ENUM

ENUM has a critical role to play in telephony services convergence. Although many carriers are adopting ENUM there are myths swirling around the confuse newcomers. In data networks, the domain name system (DNS) is responsible for converting Uniform Resource Locators (URL's) to IP addresses in order to route data traffic. The ENUM protocol performs a similar essential function of linking E.164 telephone numbers to Universal Resource Identifiers (URIs) -- enabling communication services to use traditional phone numbers to set up calls over IP networks. Unfortunately, there's a good deal of hype and confusion around ENUM, which might lead carriers to delay ENUM implementations. That delay would be a mistake... more

An Interview With Richard Whitt, Google’s Washington Telecom and Media Counsel

I recently had the opportunity to interview, Richard Whitt, Google's Washington Telecom and Media Counsel, who will be one of the keynote speakers at the upcoming Emerging Communications Conference (eComm 2009) being held on March 3-5 at the San Francisco Airport Marriott. The following is the transcript of our phone conversation and the audio recording of the interview. more

Hunting Unicorns: Myths and Realities of the Net Neutrality Debate

In many ways, the emotionally charged debate on Network Neutrality (NN) has been a lot like hunting Unicorns. While hunting the mythical horse could be filled with adrenalin, emotion, and likely be quite entertaining, the prize would ultimately prove to be elusive. As a myth, entertaining; but when myths become reality, then all bets are off. The Network Neutrality public and private debate has been filled with more emotion than rational discussion, and in its wake a number of myths have become accepted as reality. Unfortunately, public policy, consumer broadband services, and service provider business survival hang in the balance. more

Call for Telecom Industry Wake-Up

As many of you know, I'm launching the Emerging Communications (eComm) conference -- taking place next month in Silicon Valley, at the Computer History Museum. Communications innovation has been stagnant, in my opinion, for nearly a decade. Telecommunications and Internet communications both seem to be at somewhat of an impasse. The communications industry needs a forum to help break through the stagnancy and highlight the huge opportunity space that is emerging. The stagnancy has been strikingly more so in telecommunications... more

Infrastructure ENUM

After much initial fanfare a couple of years ago ENUM has matured to a state where it is currently yet another under-achiever in the technology deployment stakes. ENUM initially presented itself as a very provocative response to the legacy telco position of monopolising public voice services through their exclusive control over the Public Switched Telephone Network (PSTN) and the associated controlling position over the telephone number space... The perception was that ENUM was going to dismantle these levers of control and open up the voice market to a new wave of competitive carriers. If the address plan was the key to the PSTN, then ENUM was intended unlock this network and position the new wave of Voice Over IP (VOIP) carriers to take over any residual treasures of the traditional voice market. Events have not played out according to these expectations... more

Up to 300 Megawatt Worth of Keepalive Messages to be Saved by IPv6?

The Time Square Ball bringing in 2008 had more than 9,500 LED bulbs displaying 16 million colours while consuming power equivalent to about ten toasters. This compares to 600 incandescent and halogen bulbs adorning last year's Ball. Easy to forget that most mobile devices used by Time Square revelers were behind IPv4 NAT's and that always on applications such as Instant Messaging, Push e-mail, VoIP or location based services tend to be electricity guzzlers. It so happens that applications that we want always to be reachable have to keep sending periodic keepalive messages to keep the NAT state active... more

Parsing Hype From Hope: Will ENUM Spark Changes In Telecom?

In the beginning there was silence; then, silence begat communication, and communication begat more communication and, ultimately, group communication formed and begat a primordial "network" of communication that gradually and inevitably increased in effectiveness and complexity: there were only signal fires at first but, then, there were cave drawings, carrier pigeons, shouting from hill-tops, smoke from fire, lines of cannon fire, the telegraph, Alexander Graham Bell, and, finally, the network of networks known as the Internet. But, is that it? Is there not something more impressive in its impact upon communication than the Internet? What more might one desire than the dynamic wonders of the Internet, you ask? Well, what about ENUM? "E-What!?" more

What the Net Did Next

During this slow and long lull of domain name policy and ICANN related news stories, I thought it would be a good time to bring an article by BBC News Online technology correspondent Mark Ward to the attention of the CircleID community. In it, ICANN Chairman of the Board Vint Cerf reflects on the history of the Internet and his involvement as somewhat of a "midwife," rather than the "father" title he doesn't like. He also looks to the future and identifies two key, fundamental changes that will shape the next stage of the Internet. As he puts it, they are VoIP and ENUM. more

The End of the “Skype as Bandit” Era

And so it ends... Skype was always always a fun company to write about because they were always a bit of a rogue. The scrappy little startup that took on the megacorps of the telecom industry... and won in so many ways... look at their leading % of international calls... or the fact that per-minute call costs are now very clearly being commoditized down to zero... more

FreeNum Links Phone Numbers to the Internet

I loved John Todd's ETel presentation (podcast) on FreeNum, a scheme for bringing phone numbers to the Internet. Of course, I love identifiers and addresses and all that they enable, so it was a natural. Suppose you were a university campus and when you looked at your phone bill, you noticed that a lot of calls were to other universities. You've got a VoIP telephone system; they've all got VoIP telephone systems. You might wonder "isn't there some way to route these calls over the Internet and save some serious money?" The answer, of course is "yes" but making it usable is a little harder... more

Annual Global IP Traffic Will Exceed Two-Third of a Zettabyte in 4 Years

Annual global IP traffic will pass two-thirds of a zettabyte in four years according the Cisco's Visual Networking Index report. The economic downturn has only slightly tempered traffic growth and the global IP traffic is expected to quintuple from 2008 to 2013. Cisco predicts IP traffic to grow at a compound annual growth rate (CAGR) of 40%. more

Phone Always Busy? Must be DDoS on VoIP Network

Amidst the fascinating news from the SCO saga, preparing for SANS London and contributing to the Unix timeline project at Grokline my eyes caught a piece of rather distressing news on the BBC. It appears that BT (British Telecom) intends to move its current phone network to an IP-based network by 2009 thereby sending the circuit-switched technology off to the attic. The real question is: can we guarantee the same level of reliability on VoIP as we had on circuit-switched telephony when the stated aim is to carry both voice and data traffic down the same cables (or fibres more likely)? more
