Just been on DTUs' website, Seems like they are working on a new internet! Well routing system at least.
The reason the net is so slow at times is, as pointed out, bottlenecking. Consider data as a letter, The letter is posted down the wire, but it dont know where to go, so it stops at evey letterbox to check, if not the one its sent to it goes on to the next. Strangly enough, the royal mail figures this one out yonks ago. All the letters, to Lonon just put in a big sack, the whole sack gets sent to London, then gets sorted there! This is what they are trying to do, only with data. Package data going the same way so it gets sent out in big lumps and as the package gets send round, the new router system will pick off the data as it gets to the main ip address, town, if you like, the road then house nr.
So Once they get the super fast network, AND the faster routing system things are really going to fly.
Untill that time I will just have to settle for my 20Gb line and learn to type faster.
