Creating a Backboneless Internet?
Peter Trepan asks: "The Internet is the best thing to happen to the free exchange of ideas since... well... maybe ever. But it can also be used as a tool for media control and universal surveillance, perhaps turning that benefit into a liability. Imagine, for instance, if Senator McCarthy had been able to steam open every letter in the United States. In the age of ubiquitous e-mail and filtering software, budding McCarthys are able and willing to do so. I Am Not A Network Professional, but it seems like all this potential for abuse depends upon bottlenecks at the level of ISPs and backbone providers. Is it possible to create an internet that relies instead on peer-to-peer connectivity? How would the hardware work? How would the information be passed? What would be the incentive for average people to buy into it if it meant they'd have to host someone else's packets on their hard drive? In short, what would have to be done to ensure that at least one internet remains completely free, anonymous, and democratized?"
If Bit Torrent is of any example, this would be a bad idea. One day you may be able to get to Google fast and then the next, it may take forever to load.
Peer to Peer internet would be horrible. Not only would it be unreliable, but at time slow.
Sure some agencies can access our information because it's centralized, but if we don't want them to see something, it's not hard to encrypt it. Hell I'm even working on an encryption application.
It would look an awful lot like the internet we have now.
Except for, you know, the Tier 1 ISPs, on whose networks practically all our traffic passes at some point.
Control them, and you control the net.
May the Maths Be with you!
I think that response may have missed the point of the submitter's original question. I read it as "is there a way to prevent all traffic from traversing predictable routes and hubs, thereby disallowing any entity from collecting all of one's transmitted data and using it against one?"
Essentially what the submitter is interested in is a meshed network, which to my knowledge is the only network topology yet created which does not use hubs, centers, or buses to carry conglomerated traffic. Remember that things like bittorrent, bgp (less so), and other similar protocols are really creating "virtual" meshes, not real ones - all of your traffic (and that of every other person in your segment) is still travelling to your ISP, and that to their backbone. So anyone who sits at those hubs or backbones would be able to see all your torrent traffic, and who it is going to/from - it is only the separation of the ISPs and the RIAA/MPAA/FBI that keeps them from knowing your every move on the Internet! (Encryption and proxies help, but it aren't a foolproof solution, btw.)
Also, TCP is designed to be fault-tolerant, but also semi-optimizing, taking the shortest perceived route to its destination. So unless a backbone is down, most (if not all) traffic from you to a host between which the backbone sits will travel on that backbone, very predictably. TCP is not privacy-sensitive.
The short answer is that in a wired world, there is no feasible way to create a mesh. The strength of the mesh is algorithmically tied to the number of other nodes each node is connected to. So unless you're going to dig up the yard between you and, say, three of your neighbors, and they and two more of theirs, and so on, across the entire country, you will end up with a topology which looks more like what you've already got, with a smaller number of larger rings and stars, each funneling through a central location.
In a wireless environment, the possibilities are much better. Some police precincts in the U.S. have been experimenting with mesh-networked radios, where each radio is a repeater as well as a transceiver. Thus a linear configuration of radios could extend the range from perhaps a 30-mile radius to a 60-mile-per-radio diameter for as long as the chain is unbroken. This isn't the optimum configuration, however, since it is presumed that one would want redundancy, so you would be forced to configure the mesh in such a way that you could talk to at least three other nodes at any given time. This requires a very high density of nodes, so it would work much better in a more densely-populated area than one nodes are scarce.
I hope that answers the question.
