The media is filled with hyperbolic claims that "Our network is the fastest!" And there are many so-called "Speed Test" tools available on the Internet. Most are easily run in a web browser. Should you trust those tools? Not really. The popular speed testing tools provide a very narrow and limited measure of network "speed." It is quite possible that a network that is rated as "fast" could actually deliver poor results to many applications. Why is this so? more
I posted reviews of important LEO-satellite Internet service developments during 2017, 2018 and 2019. I've updated those posts during the years and have 18 new posts for 2020. In 2020 we saw increased effort from China, OneWeb's bankruptcy and restructuring with new ownership and prospects, Amazon investng in space-related infrastructure, Telesat making steady progress, SpaceX making rapid progress and satellite and debris tracking and collision-avoidsnce service startups. The following are brief summaries of and links to the 2020 posts. more
Earlier this year, at the CES show in January, the big cable companies discussed their vision for the future. They introduced the concept that cable networks would be able to deliver 10-gigabit broadband in the future. They labeled the promotion at the show as 10G. I didn't write about it at the time because I assumed this was a gimmick to give some buzz to this show in the middle of the pandemic. But lately, I've seen that they are still talking about the 10G initiative. more
I believe Mobile Information and Communications Technologies (ICTs) are and very well remain powerful and best-suited technologies that will help provide connectivity and digital access in a much faster and cheaper way for developing countries of the globe. Thus, they are to be leveraged within their most strategic and profitable functional or usage contexts. Mobile access technologies along with relevant innovations have formed a powerful springboard for the Internet to be significantly accelerated in terms of access, usage and penetration. 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
Inspired by expansion announcements from companies such as Netflix and Airbnb into Cuba, Fabián E. Bustamante, professor of electrical engineering and computer science in the McCormick School of Engineering, and his graduate student Zachary Bischof, conducted research examining feasibility of the business ideas given the region's notoriously weak network infrastructure. more
The end of the year is approaching which seems to be a harbinger of Internet disasters. Four years ago (on 24 Dec. 2004), TTNet significantly disrupted Internet traffic by leaking over 100,000 networks that were globally routed for about an hour. Two years ago (on 26 Dec. 2006), large earthquakes hit the Luzon Strait, south of Taiwan, severing several underwater cables and wreaking havoc on communications in the region. Last year there was a small delay. On 30 Jan. 2008, more underwater cables were severed in the Mediterranean, severely disrupting communications in the Middle East, Africa, and the Indian subcontinent. Calamity returned to its customary end-of-year schedule this year, when early today (19 Dec. 2008) several communications cables were severed, affecting traffic in the Middle East and Indian subcontinent. more
The success of the internet demonstrates that we now depend on network operators to assure that services like telephony work. The carriers are pushing back on neutrality because their business model is threatened by a level playing field. We should be encouraging innovative internet-native business models rather than working to preserve an industry threatened by innovation. 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
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
I've been having arguments about Network Neutrality with a lawyer. My position is that you can't adequately regulate ISPs to be neutral, because there's no agreement what "neutral" means in practice. He points out that the courts aren't interested in technical details like what packets are dropped, it's that all traffic has to be treated the same, and ISPs should just figure out how to do that. So I contemplated a city with Plumbing Neutrality with the simple rule that all people must be treated the same... 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
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
In June 2009 we mused in these columns about Long Term Evolution standing for Short Term Evolution as wireless networks started to drown in a data deluge. It is January 2012 and we keep our heads above the mobile data deluge, even if barely, thanks to a gathering avalanche of LTE networks. Even the wildest prognoses proved conservative as the GSMA was betting on a more 'managed' progression... more
Someone asked me a question today about Google's new partnership with Sprint. Sprint/Nextel is the third largest wireless carrier in the U.S., falling far behind Verizon and AT&T -- who together control 51% of the wireless market. (Sprint services are also resold by Comcast and Time Warner as part of their packages.) Sprint has announced it won't bid in the 700 MHz auction. Sprint has other plans... more
