[AusNOG] Discussion point: Why aren't the NBNCo tails symmetric in speed?

[Skeeve Stevens]

Hey all,

I am sure this will spurn a healthy discussion... perhaps with conflicting
views...

But I was wondering the other day 'Why aren't NBNCo tails sold as symmetric
speeds?'

Considering:

- The transit the RSP buys is symmetric (nearly always)
- The network core of the RSP is symmetric
- The handoff to either NBNCo or an aggregator (and then NBNCo) is pretty
much always symmetric
- The PoI's core is symmetric
- The fibre to the home is symmetric capable
- The NTU is just ethernet - symmetric
- Anything they plug into the NTU is symmetrical - ethernet

Google Fibre in the US is 1G/1G in speeds...

So... unless I am missing something obvious (always possible)... Why are
NBNCo tails not sold as symmetrical speeds?

I am not sure why there is this artificial design in these products to make
them asymmetric.  There doesn't seem to be any gain by doing this that I
can think of.

Gone are the days of DSL like speeds and unbalanced design... even ATM was
symmetrical.

Keen for peoples opinions.
