A while ago I wrote a plan for a Leraar on Demand (teacher on demand). The idea was that we could record good teachers, while they explained their subjects in class and then put the video online. This way the students could access the teachings even though they might have missed the class, had forgotten it or similar problems. The idea originated during beer nights with a group of friends at Twente University. It had been pitched to the faculty of Eductional Technology there, but didn't receive attention. I tried to pitch the idea to Kennisnet and the Ministry of Education in The Netherlands, but I didn't find anyone who was really interested and as it isn't my main field so I didn't pursue it full force.
I thought about entering the idea into Google's 10100 project as I still think it's a great idea. It would be great for both the First as well as the Third world. In both the First and the Third world we have a huge lack of good qualified teachers (both in numbers as well as quality). Fortunately I did a bit of research tonight and you know what, there are now two initiatives pursuing the same kind of idea. One in Sweden called "Teacher on Demand" (looks very good) and one in the US called Teacher Tube. So I am not going to submit it to Google as I'm hardly original anymore. However I do want to spread the word on these good initiatives and it's nice to see good ideas will find their way.
What I am still missing is that not an entire curriculum has been put online and can be downloaded. That would be cool. It would allow students to really search for the stuff they didn't understand well. Also it would allow third world countries to download these movies and distribute them via DVD's. At 35 dollar for a DVD player, this has become an idea that can be easily realized.

Aftappen in Nederland, Hoofdstuk 13 uitgelegd.
Apologies to my international friends, but this one is in Dutch. I was given the opportunity to give a class at Leiden University on Chapter 13 of the Dutch Telecommunications law. This is the (revised) presentation.
Dit is een presentatie die ik gegeven heb in een gastcollege in Leiden. Erg leuke ervaring. De feedback heb ik gebruikt om vooral de eerste sectie meer uit te breiden. Ik hoop dat de Nederlandse lezers er plezier van hebben en het studiemateriaal waarderen. Mocht je vragen hebben, dan hoor ik het wel. :-)
De centrale stelling is: In Nederland kunnen we tappen omdat we het op orde hebben. Ik had nog wat meer kunnen doen met uitleggen hoe het buitenland werkt, maar daar kan ik later nog wel eens wat tijd aan wijden. Zie anders Stratix en Norton Rose over Aftappen in het Buitenland.
Addendum
Ten aanzien van webhosting bedrijven geldt dat zij veelal niet onder de Telecommunicatiewet vallen. Een ruwe sortering van de branche levert de volgende indeling van de rollen die partijen spelen:
- Pure colocatie - leveren een pand, een rack, stroom. De klant levert zelf de computer, doet het beheer etc.
- Verhuurder van computer rekencapaciteit: Levert een computer (of een deel van een computer) waar de klant mee kan doen wat ie wil. Wordt veelal geleverd met een netwerkverbinding naar het internet. (theoretisch gezien hoeft dit niet)
- Systeembeheer: Voert voor de klant beheer op een computer/netwerk. Klant kan eigenaar zijn van de systemen of deze huren van derden, deze systemen kunnen staan bij de klant of ergens anders.
- Applicatiebeheer: beheert specifieke software voor de klant, levert soms wel en soms niet de licenties voor het gebruik als onderdeel van de dienst. Bv een CMS. De klant doet zelf de content, kan wel of geen eigenaar zijn van de computer etc.
- Content/designbeheer: beheert de content voor de klant.
Dit zijn allemaal rollen die niet zoveel met telecommunicatie van doen hebben. Of het een CMS, mailserver, VoIP server of eCommerce applicatie is, de functies lopen steeds meer in elkaar over. De beheerder routeert het telecommunicatieverkeer niet.
Qua telecommunicatie heb je twee opties.
- Inkopen bij een leverancier van een toegangsdienst. (bv een ISP of andere telecomaanbieder). Geen mogelijkheden om zelf verkeer te routeren. Nog steeds niet tapplichtig.
- Zelf gaan routeren. (vergt in de internetwereld een AS-nummer en eigen IP-space) Pas dan ben je echt een telecommunicatienetwerk of dienst aanbieder.Dit betekent dat je dus ook je eigen aftapverplichting moet regelen. (Andere partijen kunnen de tap niet meer uitvoeren, want je kunt zelf je eigen routering doen dmv BGP)
Disclaimer: Dit is mijn mening, geen uitspraak van de Hoge Raad.

Safaricom, M-Pesa is just cool.
This is just cool. Bart de Rijk, a colleague at Logica Management Consulting went to Kenya to help a micro-credit organisation that is supported through Logica's Bloom corporate responsiblity initiative. There he learned about Safaricoms M-Pesa, mobile payment platform. M-pesa allows anyone with a mobile phone to recieve money from a Safaricom customer. In a country where most people don't have a bank account this has become the default bank payment system. It started 15 months ago and currently carries €200 million per month. That's 5% of its GDP. There is a cost involved, at 25-35 eurocents per transaction it is not cheap, but it is still appreciated (by the people, not by competing banks)
My colleague learned about how much it was appreciated when he asked a group of women who formed a micro-credit group if they would prefer to pay their loan via mobile payments. The resounding answer was: YES PLEASE. It saves them from making long walks to meetings, risks of robbers and lions etc. To read about his experiences: Google Translate or the Bloom blog (in Dutch)

WIK report for ECTA on the economic of Next Generation Access released
WIK in Germany has finally released the PDF of the research that ECTA had been PR-ing for months already. The WIK-report on economics of Next Generation Access networks is a very handy overview of a series of research papers on FTTH (including mine). It contains a summary of many research papers and a state of play in various countries, like the US and Australia and it models the roll out of NGA networks in various EU countries. Some interesting tables are:
There is also a presentation available:

How the internet works: Peering and Transit
A while ago I wrote an article here on Peering and Transit and Ars Technica picked it up and wanted to publish it on their site. I reworked it for them and now here it is. Unfortunately I missed that it had been published for a couple of days, but still cool to see how many people have read it. Please follow the link here:

Telecom Cool Wall
Top Gear, the hugely successful BBC car program, has an item called the Cool Wall. Its the most subjective way of dividing cars up from subzero, via cool, uncool to seriously uncool. An Audi TT is seriously uncool a Landrover Defender is subzero.
I thought I do the same for the telecom industry. Being cool or uncool is as subjective here as it is there. Cool is defined as novel, alternative, fun, smart,benefiting the end-user and society. Uncool is benefiting the company and the company alone. I would love to hear readers opinions too
To quote ICON at the end of the Salone Internationale del Mobile 2005 (design): “We also make no apologies for the heavy representation of Dutch designers and brands: Milan once again shows how this small nation continues to produce the most innovative and intelligent design.”
The same goes for the Telecoms industry, though it isn't the best in everything, the climate still is exceptional.
Subzero
Free (France) 30 euro a month buys you 28mbit/s DSL (design their own DSL modems), free calling in France and to fixed numbers in 50+ countries, IP-TV, HD-TV, recorder, TV-Perso + native IPv6 (thanks Jap), etc. It has redefined the French broadband market by teaching marketeers that its not about new services that generate new revenues, but that it's about delivering more for the same money. Delivering something new every month drives churn to 0%. This company is so cool that it actually upped the ante by investing in fibre networks! For 30 euro per month of course. It is the perennial favorite for the fourth French mobile license, sending shivers up the spines of it competitors. Best of all it makes a healthy profit every year.
Internet Exchanges (mostly Europe and Asia) Most internet exchanges are cool. They are the not-for-profit associations (or similar) where ISP's interconnect their networks. The effect of internet exchanges has been massive competition in the European telecoms market. Their stats are flabbergasting (400Gbit/s traffic in Amsterdam). People working for Internet Exchanges are also good for having a beer with that's bonus points. Sub-zero then.
Internet Network Geeks: Beards, T-shirs and Sandals. Most of these men are great to have a beer with. They know why the network works. Because it imposes as little constraints on the end-user as possible. Most of them will not try to sell you a dysfunctional protocol or worse force it unto you by government regulation (though DNSSEC might be an exception)
Cool
Rabo Mobiel (Netherlands) A bank with its own MVNO. Cheap calling included with integration with your bank account. Better even, they've introduced SMS payments for everybody in The Netherlands, regardless of whether they have a bank account with the bank. All you need is a mobile phone number. That is just cool.
Telekom Slovenije (Slovenia): They are an incumbent, so that almost defines them under uncool or seriously uncool, but they have their own FTTH program called F2, without being pushed by anyone, just a general idea that it might be good to the country (I think). Just realizing that dream, makes you Cool in my book.
KPN (Netherlands): The smartest incumbent in Europe and maybe the world. Decided a while ago to invest in an All-IP network, which meant VDSL2 50mbit/s symmetric to every home. Now take that BT, that's what you call a network upgrade... And of course a brilliant way to kill of the competitive DSL-network. On the one hand it was forced by the potential of the cable industry in The Netherlands, but it has done so without the mistakes of fighting over the investment and access to it with the regulator. Much smarter then Deutsche Telekom and BT again. It knows exactly how to appease its shortsighted shareholders and still invest in FTTH. Yup, by investing in Reggefiber for 41%. You just know they will be the reigning incumbent for the next 50 years in The Netherlands, leaving the scraps for others.
FON and Eduroam: Fon and Eduroam are cool. Sharing wireless is cool. It should be mandated by law that all wifi access points should be shared amongst the customers of the ISP. Ofcourse almost no incumbent does it, because it might hurt their mobile data revenues.
Google: Google is cool, but getting less and less so. It used to be you wanted to talk to the Google guy at a party... in the Telco world I'd much rater shake hands with FON, Free, Internet Exchanges etc. Their ideas were once the coolest on the planet. Now they are just part of a larger group. Google is good at ideas, but not always at execution. Their bluffs (Android and White Spaces) in the telecom business are amusing and they are the only thing that really grabs the attention of Telco CEO's, who mistakenly see Google as a competitor. However all their forays in the telco market will result not result in Google becoming a telco, but hopefully scare the telco's into not seeing themselves as application and content providers.
Uncool:
British Telecom: There is much against BT to be listed in the Cool section. Incumbents are not cool. BT's 21CN is not cool, as it's all hype and nothing of substance to the end-user. Only delivering ADSL. Expensive backhaul (Ofcoms fault but still). Whining about the fibre investment (better then Deutsche Telekom), dumb enough to sell mobile branch. Only thing going for it is its cooperation with FON. That's Cool. Fon is cool, but the association is not enough to get BT on the cool list.
Reggefiber: Reggefiber is behind most investements in FTTH in the Netherlands. Therefore it should be cool. The problem with Reggefiber is that I see only calculations and no conviction. They haven't offered novel things in the market, nothing to brag about except connections. My image of someone working for Reggefiber is that of an accountant. Not cool.
Cable companies: I don't know any cool cable company. Some smaller ones like Reka, Kabel Noord and maybe Caiw may come into touching distance of being cool, but the big brothers, Comcast, Virgin, UPC, Telenet, Kabel Deutschland just aren't. They've promised us everything and haven't delivered a thing. Video on Demand anyone? ah yes, that's something iTunes gives us. Cable companies delivering fibre? Only in the advertisements, never to the end-users. Never a front runner, often only a runner on paper. So why are they not on the seriously uncool list.. well they sometimes keep the incumbent honest, like in the Netherlands.
European Commission: Mrs. Reding has many qualities that would list her in the subzero section. Taking on the mobile sector is really cool. However the solutions generally don't lead to permanent competition. The EU way of regulating roaming is a cent at the time. My mobile roaming solution (kind of carrier preselect for roaming) would solve it. The Commission is getting better at working on tough problems like structural separation etc. However it is an undemocratic institution that so often caused the problems it is now trying to solve, including sanctioning the GSMA-cartel. So the good stuff is keeping it from being seriously uncool.
Seriously uncool
Incumbents: Almost by definition they're uncool. Some even seriously uncool. They've been given this great asset and a perennial monopoly, that is impossible to crush. But instead of using it in a benevolent anti-competitive way (the way KPN works) most of them are just plain evil. Worse still almost all of them have cornered both the fixed and wireless market and their steps into the FTTC market will kill of any potential the competition may have.
Mobile companies (and the GSMA): In Europe all of them are money hogging, price fixing, cartel supported, marketing companies. It's not even about telecoms anymore. Most of them wouldn't know why the roaming rules are the way they are, why we're paying outrageous interconnection tariffs etc. The GSMA even argued for increasing traffic charges if internet traffic crosses a border. Hello! It does offer great value to the shareholders. However overcharging is only cool if you know your doing it and the customer doesn't. Mobile are completely the other way round. They have no clue about their business and the customers know that they are being ripped off.
Deutsche Telekom: In 1994 my student room had more bandwidth (10mbit/s) to the internet than all German universities together. The main cause: Deutsche Telekom. In Germany connecting a fax or modem to a phone line was illegal --> Deutsche Telekom. Even today: VDSL2 is a service according to Deutsche Telekom and therefore exempt from EU regulation. Are you kidding, a modulation technology cannot be a service. All this results in an enormous legal fight with the EU. They could have done what BT does. Same thing, different reaction. Oh come on Germany will never improve on a national scale as long as DT is there, seriously hurting its competitive chances.
North American Telco's: Yes Canada that includes you too (except for some bits touched by Bill St. Arnaud) None of them are cool. Most of them are very seriously uncool. Level 3 and Verizon are a bit more on the positive side. All the others are a shame for the industry. Passive collusion is rampant in the industry. All their employees seem to be lawyers. They seem to be clueless about what's going on in the rest of the world and every investment in the network is seen as an unbearable burden. Yuck. Even Munifi and FTTH initiatives in North America have the image of being a miserable failure. About the only thing good in North America is the absence of regulated mobile termination tariffs... unfortunately this is more then offset by all the rest.
I thought I do the same for the telecom industry. Being cool or uncool is as subjective here as it is there. Cool is defined as novel, alternative, fun, smart,benefiting the end-user and society. Uncool is benefiting the company and the company alone. I would love to hear readers opinions too

Say no to streaming video (there is no use for it and it hurts net neutrality)
Andrew Odlyzko has written a very insightful paper called "The delusion of net neutrality". The title is a bit of a misnomer as he is not arguing that net neutrality is a delusion. Instead he picks on network providers who argue that there shouldn't be/cannot be net neutrality. The technologies used for Deep Packet Inspection are used to enable streaming and real-time communications. Real-time communications may be sensitive to jitter, latency etc. and may benefit from QoS mechanisms on an overloaded link, but any communication that is not realtime (most streaming and near-realtime) communication shouldn't have that problem. Andrew Odlyzko'sargument is very true and well worded.
Video shouldn't be streamed it should be send via "faster than real time"-download. If it is send in this way their will always be way more in the buffer, so that temporary hickups will not harm the download and once the entire movie or a section of a movie has been downloaded there is no problem at all anymore even if the network goes down. The advocates of streaming video can't bring anything against this idea, except that it doesn't allow them to sell very expensive streaming kit. A big online video farm like Youtube always makes use of faster than real time downloads for exactly those reasons. Highest Quality of Experience for the end-user and lower costs for Youtube are a killer combination. So needing to enable streaming video is not a good argument in favor of non-net neutral networks.
One argument I did miss is that "Faster than realtime" also frees up resources later on in time, allowing better overall quality of experience to end-users. I've argued this in the OECD report on Broadband I wrote. Let's say a streaming movie takes 10% of line capacity. If there are 10 parallel streaming movies at the same time, the link is full. If you allow for faster than real time downloads, if there are two users they can download the movie to the buffer five times faster than they need it from buffer. When later on in time more people come online to watch a movie, the earlier downloaders either may have finished the download already, or may be able to stop the download of the movie for a time, freeing up resources to allow an eleventh or twelveth downloade in at the same time. (for other arguments, see my rants on QoS and flow based routing)

KPN launches FTTH €65-€110/month
As of last Friday KPN launched FTTH. On their website http://www.kpnglasvezel.nl there is some information. Initially there are only 5 locations where the service can be had.
The Bronze package has 30mbit/s down for €65 and 3 up, Silver 50/5 €80 and Gold 60/6mbit for €110 . All offer a triple play including unlimited national calls to fixed lines and a minimum of 50 tv-channels with a harddisk recorder. There is VoD available, but no mention of HD-TV. http://www.kpnglasvezel.nl/nederland/?id=20
I think the bandwidth is a bit disappointing especially upstream. But hey, that's life. Hopefully competition will cure that (except, noone is competing at the moment)

The Bronze package has 30mbit/s down for €65 and 3 up, Silver 50/5 €80 and Gold 60/6mbit for €110 . All offer a triple play including unlimited national calls to fixed lines and a minimum of 50 tv-channels with a harddisk recorder. There is VoD available, but no mention of HD-TV. http://www.kpnglasvezel.nl/nederland/?id=20
I think the bandwidth is a bit disappointing especially upstream. But hey, that's life. Hopefully competition will cure that (except, noone is competing at the moment)

Interview with Benoit and with me on FTTH in Draka Nexst
Draka recently interviewed me on my FTTH report for the OECD. In the same issue of Nexst you can find an interview with Benoit Felten of Fiberevoluiton and an article on Reggefiber.
