Akamai Report: The State of the Internet Q1 2008
Akamai is headquartered in Cambrige, Massachusetts with hardware distributed around the world that, according to their Wikipedia definition, transparently mirrors web content (usually media objects such as audio, graphics, animation, video) stored on customer servers. Though the domain name is the same, the IP address points to an Akamai server rather than the customer's server. The Akamai server is automatically picked depending on the type of content and the user's network location. In addition to image caching, Akamai provides services which accelerate dynamic and personalized content, J2EE-compliant applications, and streaming media to the extent that such services frame a localized perspective.
Here's some interesting highlights from the 2008 Q1 report:
- During the first quarter, Akamai observed attack traffic originating from 125 unique countries around the world.
- China and the United States were the two largest attack traffic sources, accounting for some 30% of this traffic in total.
- Akamai observed attack traffic targeted at 23 unique network ports.
- Many of the ports that saw the highest levels of attack traffic were targeted by worms, viruses, and bots that spread across the Internet several years ago.
- From a global perspective, South Korea had the highest measured levels of “high broadband” (>5 Mbps) connectivity.
- In the United States, Delaware topped the list, with over 60% of connections to Akamai occurring at 5 Mbps or greater.
- At the other end of the bandwidth spectrum, Rwanda and the Solomon Islands topped the list of slowest countries, with 95% or more of the connections to Akamai from both countries occurring at below 256 Kbps.
- In the United States, Washington State and Virginia turned in the highest percentages of sub-256 Kbps connections. However, in contrast to the international measurements, these states only saw 21% and 18% of connections below 256 Kbps respectively.
- A number of major network “events” occurred during the first quarter that impacted millions of Internet users.
- Cable cuts in the Mediterranean Sea severed Internet connectivity between the Middle East and Europe, drastically slowing communications.
- Cogent’s de-peering of Telia impacted Internet communications for selected Internet users in the United States and Europe for a two-week period.
- A routing change by Pakistan Telecom that spread across the Internet essentially took YouTube, a popular Internet video sharing site, offline for several hours.

One Billion Web Video Viewers Predicted by 2013
Technologies discusses include content distribution networks that cache content closer to the user, peer-to-peer networks which leverage users’ PCs, and hybrid networks which combine these two approaches. This is serious business for service providers - how should they react? Bachelet recommends the following:
We've seen the Internet flip some industries upside down - the one that first comes to my mind is the newspaper business which has been cut out of significant advertising and classified revenue by sites like Craigslist. We'll see if the Pay-TV people can turn this coming threat into an opportunity.

Run a Speed Test and Support Broadband Reform in the U. S.
For the second year running, the U.S. ranked 15th among the 30 members of the
Organization for Economic Cooperation & Development in terms of broadband availability. Denmark ranked first again in the annual OECD survey, followed by a host of European and Asian nations. Indeed, while the number of Americans with access to broadband service rose 20 percent last year, to nearly 70 million people, the most in the OECD, that amounted to just 23 of every 100 residents. By contrast, the top five countries in the OECD ranking all sport per-capita penetration rates of better than 30 percent.
Lack of modern definition and policy by the FCC, the antiquated Telecommunications Act of 1996, politics, business decisions...... lots of variables have resulted in many of our global competitors like Korea, Sweden, and Japan passing us by. FCC Commissioner Michael J. Copps recently admitted:
So..... what can we as individuals do? Last year SpeedMatters.org published the first-ever state-by-state report on Internet connection speed [PDF] and they are currently collecting data for a 2008 report. You can help by running a short (< 60 seconds) speed test - your data will be included in the SpeedMatters 2008 report. Here's a link to the test:
I'll be writing more about this over the summer.

My Summer 2008 "See How Paperless I Can Become" Project
A quick scan of what's in the picture indicates I could lighten up about 90 percent of the pile - around 9 pounds - if I moved the stuff I've printed out to various electronic forms to read, annotate and file.
If I make an effort could I go without paper? Maybe. I currently carry an iPhone, an Amazon Kindle and a 13 inch MacBook. I think I've got a nice combination that I can conscientiously work with to lighten my paper load.
Here's specs on the three along with how I think I can use each:
- 4.8 ounces.
- Goes in my shirt pocket, not my bag.
- Use for email and web browsing when not near a PC.
- Also on the fly viewing of email attached Word documents, spreadsheets, PDF's, etc.
- 5.1 pounds.
- the power adapter weighs .71 pounds.
- I also carry an optical mouse that weighs 5.2 ounces.
- Use for email, web browsing, document editing, podcasting etc when convenient.
- 10.3 ounces
- Use primarily for for document reading, limited web browsing and I can even check my email using the Kindle in a pinch
- Also use to read my daily subscription to the Boston Globe
I'll write about my project progress every once in a while over the summer and will be sure to include a picture or two.

My Travels with the iPhone and the Kindle Combination
As usual, I drove early in the morning to New Haven, CT and took the train from New Haven to Grand Central Station . In the past I've lugged a notebook computer with me for work on the train and have brought lots of "hard copy" with me including reports to review, periodicals to read, etc. This trip I decided to ditch the notebook and piles of heavy paper and travel light - carrying just the iPhone and the Kindle.
Prior to leaving I converted a number of documents I needed to review to Amazon Kindle (.azw) format. Amazon provides a free conversion service for registered Kindle users for Microsoft Word (.doc), Web page (.html and .htm) and Adobe Acrobat PDF (.pdf) file formats using a unique email address. Amazon replies by email with a link to each of the the converted azw files and the user pulls the files off and transfers them to their Kindle using a USB cable. Here's a diagram outlining the free conversion service procedure:
My meeting in New York went great - the group I met with had several relevant documents that I asked them to email me as attachments so I could read on the train ride back. They ended up sending me the 4 large Word documents as attachments that I received on my iPhone. I then forwarded the documents to a pay conversion service Amazon provides that delivered converted azw files wirelessly to the Kindle for 10 cents each. Here's a diagram outlining the paid conversion service procedure:
Overall an excellent experience - it was neat to move files around from one device to another while traveling 50-60 miles per hour on the train and then read them on a high resolution E Ink Kindle screen. I ended up getting just as much work done without the laptop with the added bonus of no eye strain.

Microsoft Yahoo Round Two?
According to the New York Times, Microsoft has proposed a complex new collaborative deal with Yahoo that would not involve a full takeover of Yahoo by Microsoft. Microsoft had made an offer of $47.5 billion to outright take over Yahoo that was withdrawn a couple of weeks ago.
From the New York Times piece and in a statement released by Microsoft today - the company said it was “considering and has raised with Yahoo an alternative that would involve a transaction with Yahoo but not an acquisition of all of Yahoo.” Microsoft provided no additional details.
Here's more from the New York Times:
“Microsoft is not proposing to make a new bid to acquire all of Yahoo at this time, but reserves the right to reconsider that alternative depending on future developments and discussions that may take place with Yahoo or discussions with shareholders of Yahoo or Microsoft or with other third parties,” the company said.
It looks like Microsoft is scrambling, trying to head off a partnership deal currently in the works between Yahoo and Google, expected to be announced as early as this week.Read the full New York Times piece here.
Cable Companies Selling More Broadband Than Telcos
- The top broadband providers account for 64.1 million subscribers.
- Cable companies have about 34.7 million broadband subscribers.
- Telephone companies have about 29.5 million subscribers.
And even more interesting:
- The top cable companies added 1.2 million subscribers, representing 54% of the net broadband additions for the quarter versus the top telephone companies
- This is the first quarter since 3Q 2004 that cable added more broadband subscribers than telephone providers.
- Overall, broadband additions in 1Q 2008 amounted to 75% of those in 1Q 2007 – with cable having 84% as many additions as a year ago, and Telcos 67%.
- The top cable broadband providers now have a 54% share of the overall market, with a 5.2 million subscriber advantage over the telephone companies.
Verizon added a net of just 4,000 subscribers to its copper-based DSL service in the first quarter. It gained 262,000 customers for its fiber-based (FiOS) service during the same period.
Is the low hanging ADSL fruit picked over? The ADSL push by the telcos may be coming to an end - at least for some of the providers.
See the Leichtman Research Group study for details.

How The RIAA Catches Campus Music Pirates
Step 3: The Limewire search listing allows the searcher to manually right-click on any song entry and choose "browse host" to see all of the songs that a given file sharer is offering to others for download.
Step 4: The listing also allows the searcher to see the IP address of the listed file sharers.
So, by doing a simple Limewire search, Media Sentry gets a list of all songs being shared by a user at a specific IP address. Here's how the rest of the process works:
Step 5: Media Sentry uses online databases like www.arin.net or www.samspade.org to find out which IP addresses are registered to each Internet-service provider.
Step 6: Using this information, Media Sentry determines which traders are located at colleges or universities.
Step 7: Media Sentry compares digital fingerprints, called hashes, of know copyright song files and those being shared.
- This can be done by Media Sentry without actually downloading the suspected song, it can be done using only a TCP/IP "handshake".
- It is possible to change the hash and in cases where this is suspected, Media Sentry will actually download the song and use Audible Magic software to compare sound waves of the offered audio file against those of the song it may be infringing upon.
Step 7: Media Sentry forwards this information to the RIAA.
The process is so simple it's even something I could do! The advantage companies like Media Sentry provide is automation and speed - fast servers and custom applications can scan large numbers of Limewire traders automatically. How does the RIAA typically continue?
Step 8: A full-time RIAA employee reviews each case to make sure the claim is legitimate and that the alleged pirate is in the United States. If this is the case, the RIAA delivers a Digital Millennium Copyright Act takedown notice, asking the college to remove infringing content from its network.
According to the Chronicle's RIAA source, Media Sentry does not perform these kinds of automated investigations on traders associated with commercial ISP's (like Verizon or Comcast) - all notices received by commercial Internet-service providers are processed manually by the RIAA.

ICT, Semiconductors, Photonics and The Bats of Austin
MATEC Networks, another National Science Foundation Resource Center like NCTT, is focused on the advancement of semiconductor, automated manufacturing, and electronics education.
OP-TEC (The National Center for Optics and Photonics Education) is a National Science Foundation Center that is building a secondary-to-post-secondary “pipeline” of highly qualified and strongly motivated students and empowering community colleges to meet the urgent need for technicians in optics and photonics.
We'll also have a little time to see Austin in the evenings and will definitely get downtown to see the 1 million (or so) bats come out from under the Congress Bridge at sundown:
We're almost full so - if you want to go - you will have to move fast - register here. Join us in Austin if you can!

Virtual Worlds in the Workplace
We'll formally announce the island on July 28 at our summer conference in Austin. We believe virtual world use will continue to grow - especially as the price of fuel continues to rise and travel costs grow.
Here's a few interesting virtual world quotes from an online Special Report at BUSINESSWEEK.COM:
- IBM uses different virtual worlds for a range of activities, including project collaboration and welcoming new employees.
- On any given day, more than 50% of employees at Sun Microsystems work remotely.
- A group of Xerox researchers from across the globe meets in Second Life each week to explore how they can use virtual worlds in various areas of their business. One idea is to use these spaces to demonstrate new technologies to customers.
- When Cisco held a summit for international partners in Honolulu in April, it wanted to include participants who couldn't be there in person. So it held a virtual summit in conjunction with the physical one.
- Architect Jon Brouchoud has used Second Life for about two years to help clients of his Wisconsin-based firm Crescendo Design visualize what their homes might look like.
- Some health-care professionals see virtual worlds as a way to help train doctors and nurses in a setting that doesn't jeopardize patient safety. The spaces can also be used to train drug salespeople in a realistically busy setting, with patients and nurses bustling about.
- Retailers are using virtual worlds to experiment with different configurations for new or existing stores. The software also lets consumer product manufacturers gauge customer reactions to new promotional displays or to the relocation of their favorite products.
And....... know you read here....... HAPPY MOTHER'S DAY MOM!

WiMax Sprint / Clearwire / Comcast / Time Warner Deal Announced
Back in 2006, Mike Q and I did a podcast on WiMax, Clearwire and Clearwire's Founder Chairman Craig McCaw. Here's what we said about Clearwire back in September 2006:
Craig McCaw is a visionary, who has had an uncanny ability to predict the future of technology. WiMAX has the potential to do for broadband access what cell phones have done for telephony - replacing cable and DSL services, providing universal Internet access just about anywhere - especially for suburban and rural blackout areas.
Just like in the early 1980's Clearwire's Craig O. McCaw has been buying up licensed radio spectrum. You may not have heard of Craig but in the early 80's he recognized local cell permits being sold by the the FCC were greatly undervalued and he started bidding cellular phone licenses. He did his buying under the radar screen of the telcos and, by the time they recognized what he was doing it was basically too late - Craig had already purchased and owned licenses in most of the major markets.
Craig McCaw and Clearwire have the spectrum, the money, the partners, superior wireless broadband technology when compared to services like 3G and the experience to make this work..... think about it..... Intel makes the WiMax radio components for computers, Google creates applications that can use WiMax services, Comcast, Time Warner and Brighthouse bundle WiMax products and services and market to their customers.... ..
According to an AP post yesterday:

Will The Cable Companies Build a Mobile Broadband Network?
We're seeing some interesting customer movement in the industry - another Fortune piece from May 1 describes Comcast's first quarter earnings, here's a couple of interesting quotes from that piece:
- Comcast lost 57,000 basic video subscribers, but added 494,000 digital cable subscribers.
- The company said 65% of video subscribers now have digital service, up from 55% a year ago, and 43% have so-called advanced services like digital video recorders or high-definition TV, up from 38% last year.
- The company also added 492,000 high-speed Internet users and 639,000 Comcast Digital Voice phone customers.
Keep watching - the deal could happen as early as this week.

Corporate Mac Attack
- Mac computer sales have risen 51% over last year. This is three time the PC industry rate.
- Combining Mac, iPod and iPhone, Apple sales have risen from $5.2 billion in 2002 to $24 billion in 2007.
- Apple stock shares have risen 2,300% over the past 5 years
- Apple has predicted a 33% second quarter revenue increase, even in the face of economic slowdown.
- The Yankee Group, after surveying 250 companies, found that 87% have at least one Apple computer in their office. This compares to 48% two years ago.
- The average price of a Mac is $1,526.
- The average price of a PC is $963.
- Consumer Clout - more business people are looking at a Mac as a PC alternative.
- Snazzy Software - Mac's operating system, OS X, is (according to many) superior to Microsoft Windows in lots of ways. Many also believe OS X is less vulnerable to hackers and viruses.
- Web Computing - many believe (including myself) that desktop applications installed on hard drives (like Microsoft Office) will eventually be replaced by applications that run on the web.
- Vista Debacle - Only 10% of the corporate world has adopted Windows Vista. This has created an opportunity for Apple.
- Recruitment - Mac popularity on campus is rising. 42% of students surveyed by the Student Monitor say they want a Mac. This is up from 8% in 2003.
Pick up the latest copy of Business Week Magazine and read the entire article. For all of us in the academic world..... if we haven't yet...... it's time to start looking at including Macs in our curriculum.
