It would not crash the network.. The upstream ports would probably be in congestion that is all.

4)As for BT, well, alot you dont know about that 
5)Yes, docsis3 can provide 100Mbit symetrical, providing the network is in good shape, you dont over subscribe AND you have good network link ups, which VM do not, they are only just upgrading to 40G link ups, poor and will need upgrading yet again in the future.
6)50MBit is set to launch with STM, they are just undecided on the limits, are you seriously going to pay a high price for a premium product which your only allowed to use for 20 minutes?
Then there is the poor upload rates which they are going to supply with it, making them have the worst down/up ratio in the whole of the UK! |
1. VM are rolling out EuroDoCSIS 3.0.. It is not pre-DoCSIS 3 at all!
2. AFAIK VM are still within its budget for 50Mb/s rollout. Latest announcement to NASDAQ confirmed this.
3. 50Mb/s will be available to all customers within 12 months. You don't need to overhaul the network to rollout Euro D3.0.. You may need to do work to get the most out of it
5. Core uplinks has nothing to do with ability to provide very fast upstreams.. The requirement will be to support QAM64 in the upstream which as Trax is correct to point out will require large amounts of work in the HFC network.
6. Some people will be quite happy to be able to use 50Mb/s for what ever limit they have during the day/evening just to get 50Mb/s for the overnight downloading
I still think that the initial upload speed will quite rapidly evolve to something more suitable/acceptable, but we will have to see won't we?
