Hi NANOG,

Not so long ago I learned about Open Access Fiber Networks.  I'm quite curious about how these are actually implemented.  I'm able to find boatloads of marketing material and management-targeted boilerplate, but I've not yet been able to find any technical resources.

My first thoughts were:

* Are these just massive VPLS networks?

* Are they just giant L2 networks?

I can't imagine that either of the above would scale particularly well.

I'm looking for any books / papers / config guides / magic tomes / etc on the subject.

Can anyone point me in the right direction?

Thanks,

Mark
