[AusNOG] Netflix, AWS and Softlayer vs. Australia

[Tony]

I fear we're straying wildly off-topic, but aren't they doing a 32-way split on 2.5Gbps of bandwidth ? Even if all of your 15 users are on 100Mbps plans (the max available right now) then they wouldn't be able to saturate the 2.5gbps bandwidth available (ie. 15 * 100 = 1.5gbps) ?
NBN design specs also state that for SDU:
"Extra fibres shall be allocated to provide future capacity. In total the effective allocation on average is three fibres per premises."
And for MDU:
"For the range of MDUs from Small to Large, if contained within the same building or in close vicinity, a ratio of 1.5 fibres per residential dwelling is used."

So maximum number of premises connected right now should in theory only be 23-24 per splitter for MDU (32/1.5) and much less for SDU and hence under the maximum bandwidth for each split.

There isn't that much chance for congestion on the NBN fibre tails.

I'd be surprised if they didn't already monitor per customer volumes 
anyway at some level, knowing how many end users are on which splitter 
and how much data they are pushing at what time would be important to 
balance congestion. IE the case of 15 heavy users all on the one 
splitter, you can shuffle those users onto different splitters in the 
one FDH so they don't tread on each others toes.
