Is Comcast Impairing Vonage?

On the one hand, the big telcos are chanting the mantram, "We shall not block, impair or degrade any content, service or application." On the other hand, they're saying, "There's no problem. We don't need a law until there's a problem." Well, now. Mitch Shapiro over at IP & Democracy, points to Russell Shaw's post that says: "I have been noticing a growing number of posts in which many Vonage users and Vonage Forum Members have been complaining about the quality of Vonage calls over Comcast broadband connections..." more

Examining the Reality of Convergence

If there is one word in the telecommunications that has suffered from over-abuse for many years now, it's convergence. The term has been liberally applied to each successive generation of communications technology for their supposed ability to solve a myriad of service delivery problems within a single unifying converged carriage and service delivery solution. Unfortunately, the underlying reality has always been markedly different from these wondrous promises, and we continue to see an industry that deploys a plethora of service delivery platforms and an equally diverse collection of associated switching and service delivery technologies. One can't help but wonder at the collective gullibility of an industry that continues to herald the convergent attributes of each new generation of communications technology, while at the same time being forced to admit that previous convergent promises have never been realized. more

VoIP Security FUD

I'm continually amazed by the amount of FUD being spread with regard to VoIP security threats. People...the sky is not falling. VoIP isn't e-mail. It isn't implemented like e-mail, it won't be implemented like e-mail (maybe "it shouldn't be implemented like e-mail" is a more appropriate statement). Following best security practices will ensure at least a level of security equivalent to current TDM systems. Best FUD I've heard this week: VoIP is insecure because you can simply put a bridge on an ethernet line and capture a stream. Hey, has anyone ever heard of alligator clips? more

VoIP’s Threadbare New Clothes

Om has burnt the midnight oil analyzing Vonage's S-1 filing, coming to the conclusion that, while churn may not be as ugly as people thought, it's still cause for concern, and apparently intensifying. His point at the end about definitions is particularly good, as excluding cancellations in the first 30-days is undoubtedly flattering to the numbers. The net present value of Vonage's lifetime customer revenues is an issue which VoIP-watchers have long speculated about with trepidation -- what if marketing spending, churn, and price competition combined to form a toxic soup which fatally poisoned the economic proposition for access-independent VoIP? more

U.S. VoIP and Broadband Policy: Today’s Debate is Off the Mark!

Despite rather rapid growth in broadband access, the U.S. is falling further and further behind other countries -- we're now ranked #16 in the world. What's slowing the U.S. down? Two threads dominate U.S. broadband policy debate today. The first focuses on traditional telecom regulation -- reciprocal compensation, universal service, e911, and CALEA (wiretap capabilities). The second focuses on "Internet freedoms," i.e., guarantees that your broadband access provider won't block or inhibit specific applications like VoIP. more

Disappearing Telephony

I'm just stepping back a minute to think about what Emerging Telephony actually is. You might have seen my earlier musings on the different philosophical underpinnings of "Western" telephony and "Eastern" thought. In an oversimplified nutshell, the Western approach puts the individual in the centre of the universe. The Eastern idea is to put the group in the middle. more

Vint Cerf Speaking Out on Internet Neutrality

In a U.S. congress hearing held yesterday November 9th, significant focus was projected on "network neutrality" and a new telecommunications bill affecting the Internet. "This bill could fundamentally alter the fabulously successful end-to-end Internet," says Alan Davidson in the post on Google blog. Vint Cerf was not able to testify because of the Presidential Medal of Freedom award ceremony at the White House, but submitted the following letter to the hearing... more

Averting the Internet Meltdown

A call to action went out: a small, California-based organization called People for Internet Responsibility (PFIR) posted an announcement for an urgent conference - "Preventing the Internet Meltdown." The meltdown that PFIR envisioned was not an impending technical malfunction or enemy attack. Instead, conference organizers foresaw "risks of imminent disruption" to the Internet that would come from an unlikely sector: government officials and bureaucrats working on the unglamorous-sounding problems of Internet Governance. more

U.S. Moving Forward with ENUM

One of the pieces of infrastructure that makes all kinds of networks work and yet gets very little attention is the directory. Directories are big business. For example, there's directory of telephone numbers run by NeuStar, Inc. NeuStar has annual revenues of $92 million. Now, according to Light Reading, AT&T Corp. and MCI Inc., together with unidentified cable companies, telephone companies, and ISPs are preparing to form a Limited Liability Corporation (LLC) that will run a process to define a new company that will run ENUM. 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

Centralizing the Net, Monetizing DNS, Getting Trendy?

In a Red Herring Conference held last week in California, Mitch Ratcliffe's offers an analytical overview of an interview held with Stratton Scalovs, VerisSign's CEO..."He then goes on to say that we need to move the complexity back into the center of the Net! He says the edge can't be so complex. Get David Isenberg in here! Ross Mayfield, sitting in front of me, laughs out loud. I am dumbfounded. According to VeriSign, the Net should not be open to any type of application, only applications that rely on single providers of services, like VeriSign. This is troglodyte talk." more

SECSAC Special Meeting on Site Finder: A Technical Analysis

After attending the afternoon ICANN Security & Stability Committee meeting, I realized that the issues involved fall into several related but independent dimensions. Shy person that I am *Cough*, I have opinions in all, but I think it's worthwhile simply to be able to explain the Big Picture to media and other folks that aren't immersed in our field. In these notes, I'm trying to maintain neutrality about the issues. I do have strong opinions about most, but I'll post those separately, often dealing with one issue at a time. more

Online Registries: The DNS and Beyond

As the world grows more connected and more complicated, we all need ways of defining, identifying and keeping track of things and cross-referencing them with their owners. The simplest way to do that is with registries -- everything from the Domesday Book, a medieval registry of land, property and people; to current-day auto registries on the one hand and the worldwide Domain Name System on the other...But now, companies and organizations have to keep track of ever more things and people, not just inside their walls but across extended organizational boundaries. Call this new wrinkle an "external registry". Finally, they may want to interact with things and people, rather than just look them up, via an "active registry".  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
