[AusNOG] Feedback wanted on optical architecture for customer handoff

[John Edwards]

Hi Bevan,

I am not sure that I can speak for any consumer of wave services at
present, but based on past experience as a scrappy operator:

1) I want to demarc as close to the source as possible - as an operator it
gives me more visibility of faults, the opportunity to strategically do
something with the contingency plan, and as a hustler it gives me the
opportunity to resell a fractional service in another datacentre

2) Always get delivery to the MMR if that's an option, otherwise if you can
get a better deal on cross-connects than I can then please deliver it to my
rack

3) Typically the cheaper non-redundant option represents better value for
money, as I can use the savings to buy more bandwidth from a diverse
provider

4) Call me old fashioned, but I prefer the troubleshooting layers of having
expensive services land on a Layer 2 device that is separate to my router.
This has the added benefit of letting me upgrade the Layer 3 device later
with a remote config cutover rather than with a laptop on the floor of a
cold datacentre, and then play router chess with the replaced hardware at
my leisure.

My experience as a telco employee is exactly the opposite of these choices
- choose the gold plated options to minimise having to train an ops or
field team to handle a fault because there are already too many circuits
and faults and the after hours team will just punt it to the day team
anyway.

John
