In general, the Glasnost results suggest that telecom and cable TV operators, when they do use throttling, do so mostly to suppress bandwidth hogs and ensure a reasonable experience for all of their customers. Mr. Dischinger, now a computer engineer in Innsbruck, Austria, said throttling was much more commonly used by operators of mobile phone networks, which have much less capacity than landline grids.

But with operators starting to sell superfast landline broadband service for heavy data users, such as Deutsche Telekom’s high-speed fiber-to-the-home service, the competition for bandwidth — and the need for throttling — will only increase, Mr. Dischinger said.

“I highly doubt it can go on forever,” Mr. Dischinger said. “I cannot envision with the current network infrastructure they have that operators can continue to support people in the long term without more investment.”

We’ve been talking about a data tsunami/flood for some time now. The basic argument has been that data use will increase massively causing congestion on the expensive cable links to the cloud and will degrade user experience.

Here is another way to tell the same story. What is happening to hotels today, will happen to countries where most Internet content is external. Asian governments and broadband suppliers have a choice: act now to increase cable capacity and thereby reduce capacity costs from their currently excessive levels (3-6 times those of Europe and N America); or wait ’till the tsunami hits.

Largely because of the broad use of iPads and other mobile tablets, which are heavy users of video streaming, the guest room Wi-Fi networks that most hotels thought they had brought up to standard just a few years ago are now often groaning under user demands.

“The iPad is the fastest-selling device in consumer electronics history, and because of it the demand placed on any public place Wi-Fi system has gone up exponentially in the last year and a half,” said David W. Garrison, the chief executive of iBAHN, a provider of systems for the hotel and meetings industries.

This means more hotel customers are unhappy with their Internet connections. Hotel owners, meanwhile, who are digging out from a two-year slump caused by the recession, will probably have to invest more money to provide more bandwidth.

For travelers, it may mean still another fee, since hotels will be paying their own Internet bills. Some hotel Internet service providers are proposing a solution that offers tiered Wi-Fi service. The lowest level, suitable for basic Internet requirements like checking e-mail, would be free, but other levels would be priced depending on bandwidth requirements. According to iBAHN, iPads consume four times more Wi-Fi data per month than the average smartphone.

The iPad represents the “final nail in the coffin” for the idea that all Internet is free, Mr. Garrison said.

Full story.

The largest cellphone carriers, fearful that a communicative citizenry will overwhelm their networks, have taken the unusual step of asking people to limit their phone calls and to delay sending photos. The carriers are also spending millions of dollars to temporarily and substantially upgrade their networks in Washington.

Panic over, then? Not quite. Perversely, the real threat may come from a reduction in internet-traffic growth, says Dr Odlyzko. Too little internet traffic, he contends, could prove to be more dangerous to the industry than too much. A traffic-growth rate of 50%, combined with steady declines in equipment costs, means revenues are stagnant, “which is hardly a cheering prospect for the industry”. If traffic growth continues to fall—it is already below 10% in Hong Kong, where high-speed access is abundant—there will be slowing demand for faster connections from operators and new equipment from vendors. But if compelling new applications drive the growth rate back up to 100%, its level for many years, there will be more demand from customers for new services and equipment. Accordingly, says Dr Odlyzko, the industry should be looking for ways to stimulate traffic growth, rather than limit it.
