Tomorrow's Networks

Robert Cringely writes:

"what network technology will be dominant, say, five to seven years from now? I can say with some assurance that it will be IP-based and that it will have the capability to appear to legacy devices just like the analog network being replaced. But on the network level, will it be DSL, digital cable, WiMax, Broadband-over Power Line (BPL), Ultra-Wide Band (UWB), WiFi, or something behind Door Number Three? On the application level will it be unicast, multicast, edge-caching, peer-to-peer, or yet something else from behind Door Number Three? The answers are "yes" and "yes," but the details vary depending on who is your ISP."

It is always a challenge making previews about the near future.
Certainly tomorrow's network will still be a mixture of the actual one, unless something else proves to be better and cheaper.
Wimax and BPL have looked for some time like a good perspective, but it is very silent now, and for what I saw they promised much more than what they could fulfil.
DSL looks to me the network with the best chances, providing that we go on, on the road of shrinking video and music files and using in a more rational way the banwidth.
I guess the Future of the Netwok is more a matter of content than a matter of bandwidth.
Without an alluring content all the bandwidth of this world is for nothing.
The request for broadband came from the Mass Market with the widespreading of P2P and exchanging of files (Music and Video).
When there was an alluring content there was also the request for more and more banwidth.

It will also be a matter of new habits and new lifestyle.

We will watch movies on the big screen, downloaded on our computer.
We will mostly call VoIP.
We will be able to connect to our home, when we'll go on holidays.
We will do a million other things. Whatever the Network will be, it will need to be: Cheap, Reliable, Available, Open.

And most of all YOU will need to be ready to run a network, being it your personal one (connecting more devices in your home) or your office's.
Because a Network needs somebody who knows how it works and how it must be handled.
From this the importance to know everything about networks.
