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.

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?

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.

Would the Real Network Neutrality Please Stand Up?

I'm sure this is something that's been raked over before, but I don't see a common understanding of what 'Net Neutrality' actually is. Despite many of the Internetorati demanding it by law. There appear to be several different camps, which you could paint as "bottom of IP", "middle" and "top". The bottomistas would see enforced Internet Protocol itself as a premature optimisation and violation of the end-to-end principle. Unhappy that you only get IPv4 or IPv6? Still grumpy that you only have IPv4 and not even IPv6? Really miserable that your VoIP packets are staggering under the poisonous load of IPv6 headers? You're a bottomista.

The Great Internet Transformation? A First Stab

Is it just a coincidence that some of the leading Internet-based application companies are pushing aggressively into network connectivity at exactly the same time the major telephone companies are pushing into content? Or are we witnessing the end of the Internet as we know it? Think back to the online world fifteen years ago. There was AOL, there was Compuserve, there was Prodigy, and there was Apple's eWorld. Sure, there were researchers and students posting to Usenet newsgroups and navigating through Gopher sites, but the Internet was a sideshow for individuals and business users. ...the online world of those days was fragmented and small. Every online service was an island. Are we going back to those days?

Whither DNS?

The Domain Name System is often though of as an integral part of the Internet. Without it, how can you ever locate anything? Well, quite easily, thank you very much. DNS is used implicitly for many services, such as web browsing. It also includes explicit extensions for a few applications such as e-mail. (I'm talking here about DNS the system, not DNS the technology that can be re-purposed to things like ENUM.) But the most notable thing about DNS is its receding importance...

Study Finds Spammers Use P2P Harvesting to Spam Millions

A recent study conducted by Blue Security reports how Internet users can unknowingly expose their contacts' emails addresses to Spammers while sharing files, music, games and DVDs over Peer-to-Peer (P2P) networks. The study has uncovered hundreds of incidents where files containing email addresses were made accessible in P2P networks.

URLs: Ontologically Speaking

I was reading David Weinberger's reports on how the New York Times is planning on tackling its "link rot" problem where articles slip behind the pay-wall. Part of their solution appears to be to replace articles with their summaries. As usual, this got me thinking about telephony. Why don't phone calls and callers have URIs or URLs? ...Let's take addressing the endpoints first. Obviously, ENUM is one way of "Internetising" the phone number address space.

It’s About Connectivity Not The Internet!

I've been trying to avoid writing about the Internet as such. With as "At the Edge" I'm looking at larger issues but can't escape writing more directly about the Internet. It seems as if everyone wants a say in Internet policy without distinguishing between technical and social issues. Today the term "The Internet" or, for many simply "Internet" is more of brand than a term for a specific technology and its implications. It has become too easy to talk about the Internet in lieu of understanding. We also see the converse -- a failure to recognize "Internet" issues.

Privacy Alert: Watch Out For FOISA

This morning, at 10 am in 2141 Rayburn, the Subcommittee on Courts, the Internet, and Intellectual Property is holding a hearing on "Internet Domain Name Fraud -- New Criminal and Civil Enforcement Tools." At that hearing, the Subcommittee will be considering a new Whois bill creating new penalties for people who provide false data when registering a domain name. We need to raise our collective eyebrows at this bill (which was suddenly dropped the evening before this hearing). The title of the bill is the "Fraudulent Online Identity Sanctions Act." (FOISA)
