NGN is Not the Internet, and Never Will

I see and hear a lot of confusion about next generation networks (NGN). In most cases people are using the term roughly as the ITU-T defines it: "A Next Generation Network (NGN) is a packet-based network able to provide services including Telecommunication Services and able to make use of multiple broadband, QoS-enabled transport technologies and in which service-related functions are independent from underlying transport-related technologies." but many people don't realize how little this has to do with the Internet... more

China’s 3G License Delay is a Smoke Screen

Last week there was a flurry of stories about China's 3G plans after Jonathan Dharmapalan of Ernest & Young was quoted as saying he expected it to take 12 to 24 months from the start of China's commercial TD-SCDMA trials, i.e. from now, until 3G licenses were issued. But there was little analysis or comment on what's really happening. 3G licenses are a formality. They delay the deployment of 3GSM & CDMA 2000 which could otherwise happen rapidly -- just plug new cards into existing radios and offer established handsets (already being manufactured, in China, for the world market). more

The End of End-to-End?

One of the major principles of the architecture of the Internet was encapsulated in a paper by Saltzer, Reed and Clark, "End-to-End Arguments in System Design". This paper, originally published in 1981, encapsulated very clearly the looming tension between the network and the application: "The function in question can completely and correctly be implemented only with the knowledge and help of the application standing at the end points of the communication system. Therefore, providing that questioned function as a feature of the communication system itself is not possible." At the time this end-to-end argument was akin to networking heresy! more

FCC’s Stanford Hearing on Broadband Practices

About 300 people attended to the net neutrality hearing Thursday hearing which began with testimony from Larry Lessig, a Stanford Law School professor and founder of the Center for Internet and Society... The meeting was called by the FCC in reaction to the news that US net firm Comcast had been exposed as managing traffic by stopping some of its 13m customers uploading files to BitTorrent and other peer-to-peer networks. The FCC has started a formal investigation to see if Comcast merits a fine for its actions. more

Does Bell Really Have a P2P Bandwidth Problem?

Bell filed its response to the Canadian Association Of Internet Providers (CAIP) submission to the Canadian Radio-television and Telecommunications Commission (CRTC) on its throttling practices yesterday, unsurprisingly arguing that its actions are justified and that there is no need to deal with the issue on an emergency basis. Several points stand out from the submission including its non-response to the privacy concerns with deep-packet inspection... and its inference that P2P usage could be deemed using a connection as a "server" and therefore outside the boundaries of "fair and proportionate use" under typical ISP terms of use. more

Locking Out Competing Providers is Bad

Today one of the headlines in Computer Sweden was that there is a dispute between Telia and the regulator PTS in Sweden. PTS requires Telia to stop locking out competing TV-distribution companies for IP-TV in the access network (DSL) that Telia runs. Specifically, they lean towards the fact Telia is dominant provider of the copper, and require Telia to competitors give access to the larger frequency band in the copper that they claim is needed for TV distribution. more

Models for Muni WiFi Completely Neglect Technology Evolution

Modern travel means interminable waits, but it's a good time for reading. I finally read Wireless Pittsburgh: Sustainability of Possible Models for a Wireless Metropolitan-Area Network by Jon M. Peha, published in February as a working paper of the New America Foundation. The good news: it's full of interesting cost estimates and projected subscriber take rates based on specific demographics in Pittsburgh, Minneapolis and Philadelphia... The flaws in this study...

Retrograde Inversion of Telecommunications Policy

Going backwards upside down. That's what we're doing with telecommunications policy in the U.S. The Comcast affair should prompt a re-examination of many decisions the FCC, Congress, and the courts have made over the last few years. When the FCC reports on its reactions to Comcast's activities, the right response will be "You're asking the wrong question." "What is reasonable network management" isn't the question we should be asking... more

Overloading the Internet? Recent Media Reports Based on Dangerous Misinformation

The London Times article (and a similar one in the Guardian) are based on dangerous misinformation. The net isn't slowing down, and nearly no technical experts believe major "overload" problems likely on the backhaul, core, or decent local loop... Net traffic per user, as documented by Odlyzko and Cisco, has been growing at about 35-40% the last five years, and that growth rate is flat and possibly down the last two years. The net has been able to handle the increase without price increases, much less overload, because the primary and rate limiting equipment (switches, routers, WDM, etc.) have simultaneously been going down at a similar 35-40%. Moore's Law is bringing costs down and capacity up at a remarkable rate. more

NY Times Grossly Misreads WEF Report

Today's New York Times includes an article by John Markoff entitled "Study Gives High Marks to US Internet." But either John Markoff is fuzzy about exactly what the Internet is or he didn't actually read the report. His title is way off base. He did interview a few people who are quoted in the latter part of the article, so there is some information in the article. But he's done a major disservice for the many who read only the title or perhaps first paragraph... more

Whose Network Is It?

A reader sent me a link last week to a piece that doesn't speak highly of net neutrality. Clyde Wayne Crews wrote an article called "Dumb Pipes, a Dumb Idea: Net Neutrality as 21st Century Socialism" that calls for legislators to reject "nut" neutrality. "Elevating the principle of mandatory net neutrality above the principle of investor ownership and wealth creation in pipes and spectrum deflects market forces away from the infrastructure development that we need..." Did anyone else see a touch of irony in a letter to the editor... more

Who Makes the Any Apps Any Handset Call?

The Wall Street Journal today reported that FCC Chairman Kevin Martin wants to reject a Petition for Declaratory Ruling filed by Skype that would establish a wireless Carterfone policy, i.e., that wireless carriers must allow subscribers to use any compatible handset to access any application, content or software. Chairman Martin has confidence that the marketplace solutions obviate any necessary FCC intervention. Such optimism must derive in part from the apparently newfound willingness of one major wireless carrier, Verizon, to support aspects of open access. Perhaps Chairman Martin has confidence in the marketplace based on the magnanimous offer of most wireless carriers to pro-rate their early termination penalties by $5 a month. But here's the rub... more

F2C: My Opening Remarks

Here are my opening remarks at F2C: Freedom to Connect yesterday: "I am honored to be among so many remarkable people. We have to be remarkable people, because we have a hell of a job to do. The Internet has been given to us. It is a miraculous gift, and a boon to our lives... at least in part because it accidentally matured outside the purview of profit and loss. Now the money has arrived. If you want to see what happens when the money arrives, look at Nigeria or Venezuela or Russia or Iraq..." more

Gaping Hole in Models for Using Spectrum Efficiently

In February, the FCC's Office of Strategic Planning and Policy Analysis published three studies (1, 2, 3) on spectrum licensing and spectrum utilization. Thanks to Nick Ruark for pointing them out... Reading on I was struck by a gaping hole in their assumptions. more

Google and the White Spaces

The white spaces proceeding is the next big opportunity for experiments in alternative ways of providing wireless highspeed internet access... A key advantage of unlicensed spectrum is that experiments in new technology can be carried out without asking the permission of spectrum licensees. To date, we have made very little spectrum available for unlicensed use and experimentation. The FCC has the discretion to decide whether the digital television "white spaces" may be used on an unlicensed basis... more
