Grand Challenges in Networks for the Next 15 Years 90
jameshowison writes "Some of the researchers responsible for the Internet, including Bob Branden of ISI and David D Clark from MIT, have outlined what they see as the grand challenges for internetworking and computation in the next 10-15 years (PDF). The report from the IRTF's 'End-to-End Research Group' discussed the question, 'How might the computing and communications world be materially different in 10 to 15 years' and how do we get there? From a universal system for location, to small-area networks, to operation in time of crisis, software radio and an agenda to reduce the energy required for communications this document tries to imagine what will be like packet-switching was for the past 15 years."

It only takes one person or company to implement things wrong, break protocol and then you have a mess. That is the grand challenge.

I've got a LAN setup running 200x as fast as the fastest WAN/Internet connection readily available (minus a special order and uber expensive DS3). And at the pace we're going, the US is getting slower and slower as far as the Internet connections go.
Right now I can completely rewire my office and home for $5k with state of the art, high end network components and have it done in less than a week. I can't get close to those speeds with my net connection for 4x that price ($20k/year).

If I look five years ahead, I worry about how to design networks and protocols that are defensible against MPAA, RIAA and generic lawsuits.
A lot of the adhoc stuff in the PDF look a bit like this something that must terrify the {MPA.RIA}A lawyers who would like to make DRM a requirement of all future network topologies and protocols.
TCP was an implicit political statement. It said "we don't need telcos to make us pay for every second of a virtual ciruit", the way the OSI architecture was designed.

Right. At one point the article mentions "a range of anti-social behavior, including spam, spyware and adware, and phishing." I personally think vigilante-style copyright enforcement should be at the top of the list of anti-social behaviors. DRM issues are probably going to have more impact on network design

You say that like there's no difference between a LAN and a WAN. The reason your LAN setup is so much cheaper is that none of your cable runs are THREE MILES LONG. You think teh intarweb runs over 100BTX Ethernet cable everywhere?

As far "teh intarweb" you speak of... nope, I don't think it runs on "100BTX Ethernet cable".. I've been in the ISP business for 10 years now and I'm pretty familiar with both ends of the Internet. The first being the provider end. The second, being the customer's end. Considering the customers pay my bills, I'm more worried about providing them with what they want.

The idea of having a GPS type device which operates everywhere is a great idea, however the problem with the current system is the need for the receiver device to be able to see satellites (i.e. the signal is line of sight only), and that buildings do a fairly good job of blocking the satellite signal.

Major change happens when an intelligent person solves a very real problem in a way that seems obvious once it's completed but that few others would have come up with.
This paper starts by dissing incremental improvements and then goes on to rehash... wait for it... incremental improvements. How can you compare "better security" to Packet Switching in terms of revolutionary technology?
In my opinion major advances in the next 10-15 years will be driven by content-based applications. Technology is cheap and is becomming a commodity. It will not make any more major leaps until there is a content driver and industry to take it there.
For example, when we can all print flat panels for wall paper what will we have to display on them? An entirely new content and distribution industry will emerge to fill these and other voids and THEN technology will again stride ahead.
