Re: Cable Company Network Upgrade

2014-07-19 Thread Ben Hatton
I don't think there are any 'budget' routers that would move the amount of
data you are looking at trying to do.

35k subs @ 240Mb is 8.4Tb/s at 100% utilization, even at a somewhat high
100:1 oversubsctiption you are looking at over 80Gb/s

While our DOCSIS network is only 4000 subs, we peak at around 1.8gb/s on
10Mb packages, while oversubscription can increase with higher speed
packages, as many users would never use that much bandwidth, some will, and
even 1% of your customer base capping out a 240Mb would take most of a 10Gb
pipe, and you still would have 34000 other subs to handle.

I can't see offering 240Mb service to over 35k subs on anything less than a
100g core, and even that would be pushing it.

Re: Evaluating Tier 1 Internet providers

So much This...  You don't realize how important this is until your
nationwide provider takes 8 WEEKS to add one network to your (already set
up and working for 20 other networks) peering.  Then decides to charge you
a fee for the change.
