Ok, ok - it's pretty hard to ignore the bombshell news that's on front pages everywhere today in Canada. It looks like Nortel is going to seek bankruptcy protection, perhaps as early as today. This may be a minor story in the U.S. business press, but it's a big story in tech/telecom, and a HUGE story here in Canada. You don't need me to tell you what Nortel means to Canada in terms of pride and joy, although that's more of a distant memory these days... more
Spam over Internet Telephony (SPIT) is viewed by many as a daunting threat. SPIT is much more fatal than email spam, for the annoyance and disturbance factor is much higher. Various academic groups and the industry have made some efforts to find ways to mitigate SPIT. Most ideas in that field are leaning on classical IT security concepts such as intrusion detection systems, black-/white-/greylists, Turing tests/computational puzzles, reputation systems, gatekeeper solutions, etc... We identified the lack of a benchmark testbed for SPIT as a serious gap in the current research on the matter, and this motivated us at the to start working on a first tool for that. more
SpaceX has unveiled its new "Starlink Direct to Cell" service, aimed at providing cellular connectivity globally via its Starlink satellite network. The newly launched website promotes the service with the promise of "Seamless access to text, voice, and data for LTE phones across the globe." more
In 2007, Johna Till Johnson, president of Nemertes Research, published a paper that hyped a so-called "Exaflood" - a kooky Discovery Institute idea about how the Internet would drown in its own data. The Nemertes press release on the paper was widely reported in newspapers. It described itself as a "... landmark study ... groundbreaking analysis ... evidence the exaflood is coming... It said: "The findings indicate that by 2010 ... users could increasingly encounter Internet "brownouts" or interruptions to the applications they've become accustomed to using on the internet." more
Virgin Media announced its intention of restricting BitTorrent traffic on its new 50Mbps service according to an article by Chris Williams in The Register. Does this mean that net neutrality is endangered in the UK? The question is important because advocates of an open Internet like me hold the UK up as a positive example of net neutrality achieved through competition rather than through regulation. more
T-Mobile has claimed a new world record in 5G upload speeds, achieving an impressive 2.2 Gbps in tests conducted at California's SoFi Stadium. Partnering with Ericsson and Qualcomm, the telecommunications firm leveraged an emerging technology, 5G Dual Connectivity (5G DC), which combines mid-band and millimeter-wave (mmWave) spectrum bands. more
Images of clouds have been used when discussing networks for quite some time. When traditional telecoms companies were selling point-to-point circuits a drawing of a cloud was sometimes used. The cloud symbol helped indicate the provider?s domain of responsibility, effectively hid the internal complexity of the network and focused on the end user. This was all fine when the product offered was an end-to-end circuit. more
Casey Lide and Thomas B. Magee of Keller & Heckman highlight an issue that anybody building fiber on utility poles should be aware of. A recent article on their website notes that in some cases, an easement obtained for using private land to bring electric service might not automatically allow an easement for bringing fiber. more
The New Jersey Supreme Court has issued an important decision on Internet users' right to privacy. The case involves a dispute about whether an ISP violated a user's privacy rights by turning over subscriber information (name, address, billing details) associated with a particular IP address. It ends up that the subpoena served on the ISP was invalid for a variety of reasons. As the user had a 'reasonable expectation of privacy' in her Internet activities and identifying information, and because the subpoena served on the ISP was invalid, the New Jersey court determined that the ISP should not have turned over the personal data... more
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
The ongoing witch-hunt from the incumbent telcos in the USA against municipalities that are trying to build their own broadband networks is continuing unabated. This is nothing new... With the economic crisis there has been a new focus on regulatory rules and the importance of the common good, next to the free market. However that message has not yet got through to the incumbent players in the USA. more
A friend who read my Creating Sustainable Network Neutrality paper wrote to say, "Help me understand what is so bad about treating different types of communications differently." That's a really good question! If you want to offer vertically integrated services on special purpose networks, such as video entertainment or pager service or telephony, I do not have a problem with that, provided you don't use your market power to impede Internet applications that offer competing services... more
Comcast, the largest broadband provider, largest pay-TV company, and third-largest telephone company in the country, distributes communications services to more than a third of the country. Today Comcast's existing overwhelming market power was on display in major public battles with (1) Level 3 and (2) cable modem manufacturer Zoom. The takeaway from today: No market forces are constraining Comcast -- or any of the other major cable distributors, none of which compete with each other. more
Primary suppliers see sales go up. ADTRAN's sales in the most recent nine months were $445M, up from $399M the year before. Calix sold $372M, up from $327M. At analyst meeting this year, both said demand had picked up. Clearfield, a supplier of fiber optic gear, was up 8%. Pai claimed, "the impact has been particularly serious for smaller Internet service providers." It was a primary justification for his Net Neutrality decision. more
Broadband; we want it, and we all depend on it; but where you live can impact access and adoption of the best that service providers have to offer. The FCC is looking to change both geographic and demographic limitations now plaguing the U.S. in the global race for broadband economic supremacy. Can a combination of a fixed and wireless-mobile strategy improve broadband economic viability by increasing access, adoption, and affordability across the broadband spectrum? more
