Perdonate se ritorno un po' indietro nel tempo per un commento sul Piano Obama sulla Net Neutrality. Nel leggere il documento mi ha colpito l'affermazione "Net neutrality has been built into the fabric of the Internet since its creation". Dato che insegno proprio Reti di Calcolatori, questa affermazione mi ha fatto accendere una lucetta rossa ed ho cercato di capire quanto fosse vera. E mi sono reso conto che è decisamente errata. In primo luogo perchè nei blueprint di Arpanet c'era l'idea di garantire la massima libertà di trattamento dei pacchetti per garantire la sopravvivenza della rete. I pacchetti anche se dalla stessa origine alla stessa destinazione possono essere instradati su percorsi differenti, per esempio. In secondo luogo perchè a partire da IPv4 ci sono diversi meccanismi per differenziare i pacchetti in Internet. Senza contare i meccanismi di IPv6. Ho capito quindi l'affermazione di Cerf in questa intervista al Washington Post http://www.washingtonpost.com/blogs/innovations/wp/2014/10/10/5-insights-fro... : "There's also some argument that says, well you have to treat every packet the same. That's not what any of us said." Qualcun'altro ha fatto una riflessione su questa affermazione di Obama ed in genere sul suo Piano?

*Net Neutrality: President Obama's Plan for a Free and Open Internet*
More than any other invention of our time, the Internet has unlocked possibilities we could just barely imagine a generation ago. And here's a big reason we've seen such incredible growth and innovation: Most Internet providers have treated Internet traffic equally. That's a principle known as "net neutrality" --- and it says that an entrepreneur's fledgling company should have the same chance to succeed as established corporations, and that access to a high school student's blog shouldn't be unfairly slowed down to make way for advertisers with more money.
That's what President Obama believes, and what he means when he says there should be no gatekeepers between you and your favorite online sites and services.
And as the Federal Communications Commission (FCC) considers new rules for how to safeguard competition and user choice, we cannot take that principle of net neutrality for granted. Ensuring a free and open Internet is the only way we can preserve the Internet's power to connect our world. That's why the President has laid out a plan to do it, and is asking the FCC to implement it.
Watch President Obama explain his plan, then read his statement and forward it on.
