I'm not advocating a wild west every man for himself, but, I think that solving end-node oriented problems at the transport layer is equally absurd.
That's not what was being suggested. The article suggested that ISPs, the providers of the transport layer service, should consider branching out and offering other value added services in addition to the transport layer, because customers want to buy value-added services and not just the raw, unfiltered transport layer. It's up to the ISP as to how they configure and manage those services. The company that I work for decided to build a separate global IP network in 20 countries to connect about 150 providers of application and data services to their customers, currently just under 11,000 of them. This IP network provides vastly higher levels of security than the public Internet and that is part of our contracts and SLAs. There is no technical reason why other ISPs could not offer similar value-add services other than a failure of the imagination. And we all know what "failure of the imagination" buys you. In the telecom industry it led to the rise of the ISP and the Internet because the incumbents could not imagine what we have today. In the U.S. political arena it led to 9/11 because the people charged with protecting the country could not imagine that a small group of people based in one of the most backward countries on earth could pose a threat to American soil. The report of the 911 commission makes interesting reading if one is able to see the abstract lessons that it draws. Many of those lessons relate to failure of imagination and failure to move on and change with the changing times.
ISPs transport packets. That's what they do.
You're wrong there. ISPs provide Internet services. That's what they have always done. In the early days they ran mail servers and web servers and news servers and terminal servers and many other things. We have gone through a period of specialization where ISPs have been differentiated into providing a subset of all possible Internet services. Some do indeed specialise in pure packet transport, but that is rare and they are usually part of a larger company that provides other services. In any case, it's time to move on and change some more, perhaps by adding new value-added services on that last mile connection.
I haven't actually seen a lot of consumers asking for protected internet.
That's because you don't work for Yahoo email or for AOL.
Do you really want an internet where everything has to run over ports 80 and 443 because those are all that's left that ISPs don't filter?
No. But I want an Internet in which different ISPs are free to offer different services rather than have a regulated environment that says that ISPs MUST offer a specific service in a specific way. I want choices. --Michael Dillon
