Well according to MIT's David D. Clark, it is. In an article in Technology Review, Clark talks about how there is a need to redesign the Internet from scratch, especially since there are so many holes in the architecture and lack of security (with viruses, worms, spam, phishing, security patches, etc.). There is NSF funding for academics and researchers for this, to find new architectures and protocols for building Internet 2.0 I guess (just like we have Web 2.0).
Others argue that the Internet is not broken, that the reason why it is broken is an OS issue (think Microsoft Windows and its' gazillion updates from Windows Update). As well, the Internet hasn't implemented the latest protocols designed to improve security like IPv6 for example. We don't need to redesign the Internet from scratch, and would it be a good idea to. If we would redesign, how would existing protocols and applications work? And how would other people then upgrade to the new infrastructure? IPv6 didn't really take off, even it was designed to improve security and assign more IP addresses, with each device having an IP address. The problem with IPv6 is that it requires installing an IPv6 stack on all the routers and network software. Who really wants to do that? And of course there's backward compatibility problems.
So, what do people think? Does the Internet need a new makeover, a face-lift, an upgrade to progress into its future?
