Is Google boosting IPv6 adoption ?

13 April 2011 by Ch. Tronche | Comments Off | Filed in Divers

This is part of my series on (Trying to) foresee IPv6 deployment.

Google is doing a lot of things for IPv6 adoption with its IPv6 program. First, it brings credibility to IPv6. When Google talks, the world listens. They have hosted a workshop about IPv6 adoption, where at least two important points where made:

about 0.5 % of internet users have a broken IPv6 connectivity, that is their computer thinks it has IPv6 connectivity, if presented with an IPv6 address, the computer will try to use it, but it will ultimately fail. Depending on your view, 0.5% may be acceptable or not (not acceptable from the point of view of Google)
T-mobile USA brought steam to the NAT64 approach by saying this was their way, and by putting some hard figures about NAT64 brokenness on the table.

However, as an ISP, for your clients to use Google (and affiliated sites like Youtube) over IPv6 by default, you need to have a special agreement with Google. This is because of the 0.5% that Google doesn’t want to lose. The point is that, for now, most ISPs still have a stock of IPv4 addresses, so their new customers have a dedicated IPv4 address to get the best possible connectivity. For these ISPs, there’s absolutely no incentive to enter into the agreement with Google. On the other hand, if IPv6 access was enabled by default, it would move large amounts of traffic to IPv6 for the ISP customers that have IPv6 enabled, pushing the ISPs towards IPv6.

All in all, I think the current Google policy of “IPv6 on agreement” restrains rather than encourages IPv6 adoption.

HADOPI (and others) and IPv6

26 January 2010 by Ch. Tronche | 1 Comment | Filed in French politics, techtalk

Tracking of internet users on the basis of their IP address seems to have some traction theses days (cf. for exemple the HADOPI law), at least in France.

With the coming exhaustion of IPv4 adresses, Internet Service Providers are putting together “transition” (permanent ?) mechanisms to make IPv6 works (when such a service do exist), with as little disturbance as possible for the existing users.

Part of these mechanisms may be to NAT IPv6 addresses distributed to their users to IPv4 adresses to keep the existing IPv4 services working. In order to do this, the ISPs will have to get the already distributed addresses back to feed the NAT mechanism.

The result: an IPv4 address will be used in succession by various users at different moments. The IP address (v4) alone won’t be enough to identify the user any more, only a set of dozens of clients.

Of course, there is a solution: to identify the user, the source port will have to be noted together with the IP address. This implies the ISP will store this information, a heavy and costly process, since the NAT associations are changed much more often than the IP addresses.

Simple technical difficulty or yet another risk of error ?

Timing can also be called into question: putting an authority like HADOPI in motion can take years, while the IP address exhaustion is predicted around 2012, forcing ISP into quick action.

Another groundless patent leads to plaintiff sanctions.

Commentaire sur "Les petits télégraphistes" de Pascal Rogard

Le billet de Pascal Rogard.

Telegraph Pole HDRImage by alexkess via FlickrSi la commission ne veut pas prêter le flanc aux accusations d’opacité, il suffit qu’elle publie le détail de ses calculs.

L’UFC peut s’agiter tant qu’elle veut, les ayant droits ont la majorité absolue dans la commission dont la composition (collège) est fixée à l’avance. Difficile de voir alors dans le siège réservé à l’UFC autre chose qu’un alibi et, dans ces conditions, la politique de la chaise vide ne semble pas si bête.

Ne pas se méprendre sur mon discours: il faut bien que des artistes touchent quelque chose de leur art (non pas les artistes, sinon le moindre guignol artiste auto-proclamé va demander à l’état d’obtenir  une rente à vie), et le principe d’une vignette sur les disques durs pour rémunérer les artistes ne me choque pas, pas plus qu’une vignette sur les voitures pour améliorer le sort des retraités.

Mais je n’arrive pas à imaginer qu’un système aussi outrageusement anti-démocratique que cette commission, dont la légitimité ne tient guère plus que du discours de ceux qui en tirent profit, pourrait perdurer bien longtemps. Si on veut une taxe, qu’elle soit votée par l’Assemblée ou décrétée par le gouvernement.

Il est vrai que ce discours est peut-être difficile à accepter pour des héritiers de Chateaubriand…

A propos de la crise

23 October 2008 by Ch. Tronche | Comments Off | Filed in Divers

J’aimerais me livrer ici à l’exercice périlleux de la prédiction.

Le choc en retour de la crise actuelle va continuer à se dérouler dans les années qui viennent de façon épisodique pour une raison que je vais maintenant un peu développer.

La plupart des parts dans des fonds de placement vendues ces dernières années par les institutions (banques et autres) aux individus, le sont généralement à capital garanti, les particuliers acceptant rarement le risque de perdre les économies de leur vie. Les fonds ont donc souscrit des assurances pour adosser cette garantie. La valeur des actions sous-jacentes auront fortement baissées dans la tourmente actuelle, et déclencheront des appels de liquidités vers les assurances déjà exsangues au fur et à mesure que les fonds arriveront à maturité.

Voilà qui nous promet une vie intéressante dans les années qui viennent…

I'm back to Firefox

13 September 2008 by Ch. Tronche | Comments Off | Filed in Divers

I’ve been using Chrome for two weeks now, and I’m back to Firefox.

Chrome is good, but it doesn’t bring anything new to me.

I’m not sure the “one process per tab” gives as much performance as Google claims. It seems slow to me when Windows must bring things back into memory.

My opinion is that Chrome lags behind Firefox for now, so I’m back.

Will Google succeed in the market with Chrome or not ? I don’t know. Google guys are smart. But Microsoft never got out the OS+office software ghetto, in spite of having some smart  guys too.

This cool site let you manage a simulated portfolio using real-world stocks and quotes, exchange analysis and even win real money ! Your goal is to out-perform the S&P 500. I’m waiting for the one with futures and the french stocks.

The server’s overloaded today, which may  be a good sign (or not).

Their ultimate goal is to leverage “collective intelligence” to make money on real investments. Will it work or not, I’m not sure (you don’t behave the same when you know it’s a game), but the idea’s cool anyway.
